Installed a sensor on my girl so i know when
#Funy jokey#I've become addicted to cheap zigbee switches and sensors#I set this up so the air conditioner in our bedroom will stop running when the bucket is almost full theres something wrong with me#It works too and i love it :')#Next up is a small switched pump that will pump the water out for a set amount of time#Directly to the balcony plants#Our windowsill is too high up to run the condensed water out with gravity sadly so some kind of reservoir with sensor and pump has to do#Also planning a dedicated channel for outside air directly to the compressor with some kind of blowback valve#I hate mobile acs for how they are designed but there are no good high capacity mobile acs on the market yet#This should mitigate most of the issues though#The main issue is the lack of separation of compression and expansion stages which is why you should use outside air for the former#AND i have an hourly energy price contract which means i should switch the ac on/of on a set of preset conditions#I love tinkering and this is both pretty cheap and actually rewarding us with much better sleep during heat waves & less fuss#Also electricity savings#I put a bunch of stuff on this kind of sensing/logic already and its so nice to see your expenses go down with little to no impact#I feel like such a dad even though i dont have any kids#All of this is completely local and relatively cheap to set up but you have to like tinkering a little#Hmu if you want some advice i can point you away from large cloud based nonsense & help with initial startup#The two investments are a raspberry pi and a zigbee dongle#Possibly also a p1 reader or similar if you want data directly from your utilities#And after that most investments should be 10 dollars max per sensor or switch and most of the ali ones will work#And even have fancy features like somewhat accurately displaying power usage and current#Sorry for extremely rambly long tags i just get excited sometimes

Stray flashlight sucked by F-35 engine caused $4 million in damage
Fernando Valduga By Fernando Valduga 01/19/2024 - 20:18in Incidents, Military
The F-35's ALIS system should soon be replaced by a new cloud-based platform.
A portable flashlight left inside the engine inlet of a USAF F-35 fighter was sucked into the engine during a maintenance operation at Luke Air Base, Arizona, in March 2023, causing almost $4 million in damage, according to a new accident investigation report.
The investigation, released on January 18, blamed the maintainer for not following the joint and U.S. Air Force guidelines as the main cause of the accident, which damaged the $14 million engine enough so that it could not be repaired locally.
However, the researchers also cited problems with the Autonomous Logistics Information System (ALIS) of the F-35 as a factor that contributed substantially. ALIS is intended to integrate operations, maintenance, forecasts, supply chain, customer support services, training and technical data, but the system has struggled with the lack of real-time connectivity, clumsy interfaces and much more.
As a result, the report states, “the substantial number of checklists and the difficulty in accessing the corrections cause complacency when users consult the necessary maintenance procedures”.
Tumblr media
The accident in question occurred on March 15, when a three-person maintenance team was completing a Time Compliance Technical Directive on the F-35 to “install a measurement buffer on the engine fuel line and perform a leak check on the new measurement buffer while the engine was running,” according to the report.
After the plug was installed, a maintainer conducted a tool inventory check, before another maintainer performed a "Before maintenance operations" inspection of the engine. For this, the maintainer used a flashlight to inspect the engine inlet and left it on the edge of the entrance.
The maintainer who performed the engine inspection then operated the engine for five minutes to check for fuel leaks. During this time, the cabin showed no indication of damage from foreign objects to the engine, but when the engine was turned off, the team reported hearing abnormal noises. The maintainer who conducted the engine operation performed another inspection and identified the damage, while the maintainer who completed the first check of the tool inventory performed another and noticed the lack of a flashlight.
Finally, the engine suffered damage to the second stage rotor, the third stage rotor, the fifth stage rotor, the sixth stage rotor, the fuel nozzle, the bypass duct, the high pressure compressor (HPC), the high pressure turbine (HPT) and the variable fan input vane, valued at US$ 3,933,106.
Tumblr media
Investigators found that the maintainer who conducted the inspection before the engine ran did not follow the Joint Technical Data warnings to remove all loose items before entering the aircraft entrance and to ensure that all engine inlets and exhausts were free of foreign and loose objects. The aviator also did not follow the instructions of the Air Force Department to "perform a visual inventory" of the toolkit after completing each task.
Finally, the report also concluded that the local practice of the 62ª Aircraft Maintenance Unit did not fully follow the instructions of the DAF, which require the individual who signed the toolkit to perform visual checks of the inventory. Instead, the practice of the unit was to make the individual who performed the operation of the engine conduct the inventory check. As a result, the two aviators involved in the accident thought that the flashlight had been found.
The ALIS factor in the accident marks another problem for the problematic F-35 support venture. The program has been affected by high costs and technical problems, and lawmakers have expressed frustration with ALIS before. The Joint Office of the Program is in the process of moving to a new "Integrated Operational Data Network", but the authorities have described it as a gradual effort - it has already been under construction for four years.

What Are Industrial Air Compressors? Exploring Different Types and Uses
Industrial air compressors are integral to modern manufacturing and industrial processes, providing the power needed for various applications such as construction, automotive repair, and heavy machinery operation. Their ability to compress air into a stored energy form makes them valuable tools in industries requiring consistent and reliable power sources. This blog will explore what industrial air compressors are, delve into the different types, and examine their varied uses across sectors.
What Is an Industrial Air Compressor?
At its core, an industrial air compressor is a mechanical device that converts power into potential energy stored in pressurized air. The compressor takes air from the atmosphere, compresses it to a higher pressure, and then stores this energy in a tank or releases it to power various tools and machinery. The stored compressed air can be used to generate mechanical force, such as running pneumatic drills, driving motors, or operating equipment.
Air compressors come in different sizes and capacities, from small portable units for smaller jobs to large industrial machines designed for continuous use. The type and size of the compressor depend on the specific needs of the industry, ranging from light to heavy-duty applications.
How Industrial Air Compressors Work
The basic working principle of an industrial air compressor revolves around drawing air from the atmosphere, compressing it through mechanical action, and storing the compressed air in a tank or cylinder for future use. Compressing air increases its pressure, converting the kinetic energy into stored potential energy. This energy can then be released when needed to power various tools and equipment.
Different air compressors achieve this compression using various mechanisms, such as pistons, rotary screws, or centrifugal force, leading to the different types of compressors available today.
Types of Industrial Air Compressors
There are several types of industrial air compressors, each offering specific benefits and designed for different applications. The main types include:
1. Reciprocating (Piston) Air Compressors
Reciprocating air compressors, also known as piston compressors, are one of the most commonly used types in industrial applications. They work by using a piston in a cylinder to compress air. As the piston moves down, air is drawn into the cylinder. On the upward stroke, the air is compressed and stored in a tank.
Single-stage compressors are typically used for lower pressure applications and consist of one piston compressing air in a single stroke.
Two-stage compressors compress air in two stages for higher pressure, making them ideal for more demanding industrial tasks.
Applications: Reciprocating compressors are widely used in manufacturing, automotive repair, and small-scale industries where compressed air is needed in short bursts.
2. Rotary Screw Air Compressors
Rotary screw compressors use two interlocking helical screws (rotors) to compress air. As the rotors rotate, air gets trapped between the screws, and as the space reduces, the air is compressed. These compressors are known for their reliability, continuous operation, and ability to deliver large volumes of air.
Rotary screw compressors are available in oil-lubricated and oil-free variants. Oil-free compressors are preferred in industries like food processing, pharmaceuticals, and electronics, where contamination by oil is unacceptable.
Applications: Rotary screw compressors are commonly used in large-scale industrial settings, such as manufacturing plants, automotive production, and construction sites, where a continuous supply of compressed air is required.
3. Centrifugal Air Compressors
Centrifugal air compressors work on the principle of dynamic compression, using a rotating impeller to accelerate the air and convert kinetic energy into pressure. These compressors are ideal for high-volume applications, where a continuous and high-pressure air supply is needed.
Due to their complex design and larger size, centrifugal compressors are usually found in large industrial plants that require high power and constant operation. They also tend to be more expensive and require precise maintenance, making them suitable for high-end industrial applications.
Applications: Centrifugal compressors are used in large manufacturing plants, petrochemical industries, and HVAC systems where high-pressure air is needed.
4. Scroll Air Compressors
Scroll air compressors use two spiral-shaped elements, one fixed and the other orbiting, to compress air. As the movable scroll orbits, it compresses air into smaller spaces, resulting in high-pressure output. Scroll compressors are highly efficient, quieter than other compressors, and deliver consistent pressure.
They are typically used in applications requiring lower pressure and where noise reduction is essential, such as in medical, pharmaceutical, and electronics industries.
Applications: Scroll air compressors are widely used in hospitals, dental offices, laboratories, and cleanrooms, where noise, efficiency, and air purity are critical.
Uses of Industrial Air Compressors
Industrial air compressors are used across a wide array of industries, thanks to their versatility and power. Here are some of the most common uses:
1. Manufacturing
Manufacturing industries heavily rely on air compressors for powering pneumatic tools, spray painting, clamping, and actuating automation equipment. In metal fabrication and machining, compressors provide the necessary force to operate machinery like grinders, drills, and hammers.
2. Construction
In construction, air compressors are essential for running air-powered tools like nail guns, jackhammers, and compactors. The portability and reliability of compressors make them a key asset on construction sites, where continuous power and mobility are needed.
3. Automotive
The automotive industry uses air compressors for various tasks, including tire inflation, painting cars, and powering pneumatic tools. In auto repair shops, compressed air is vital for running impact wrenches, drills, and sanders, providing the precision and power required to perform complex tasks.
4. Energy Sector
In oil refineries, gas processing, and power generation plants, centrifugal compressors are widely used to compress gas for transportation and storage. They are also used in turbine systems for power generation and pipeline operations, where the continuous flow of compressed air is essential.
5. Healthcare
Scroll and oil-free rotary screw compressors are critical in the healthcare industry, providing clean, oil-free air to operate medical equipment such as ventilators, dental tools, and surgical instruments. Hospitals also rely on compressed air for air filtration systems, anaesthesia delivery, and sterilization processes.
6. Food and Beverage
In the food and beverage industry, compressed air plays a crucial role in packaging, bottle filling, and product handling. Oil-free compressors are commonly used to ensure that no oil contaminants are present in the production process, keeping products safe and hygienic.
7. Aerospace
In aerospace, compressed air is used for testing hydraulic and pneumatic systems, cleaning aircraft parts, and assisting in manufacturing components. The precision and power of air compressors help streamline production and maintenance processes in this high-tech industry.
Conclusion
Industrial air compressors are an essential tool across various industries, providing reliable, powerful, and efficient compressed air for numerous applications. Whether it's a small workshop or a large industrial plant, air compressors can significantly enhance productivity, reduce downtime, and offer versatile solutions for different operational needs. By understanding the different types of air compressors—reciprocating, rotary screw, centrifugal, and scroll—industries can make informed choices about the most suitable equipment for their specific tasks, ensuring optimized performance and efficiency.

A two-stage air compressor is a type of compressor that uses two cylinders to compress air to higher pressures. The first stage compresses the air to an intermediate pressure, which is then fed into the second stage where it is further compressed to the final pressure. Two-stage compressors are commonly used in industrial settings where high-pressure air is required for tools, machinery, and processes.

From Ground-up to the Skies ELGI Compressed Air System
Case Studies | ELGi
Tumblr media
In aerospace manufacturing, tiny details matter most. For instance, if proper torque is not applied to the screws and bolts fastening an aircraft fuselage, catastrophic failures can result. Compressed air is used to power the tools needed to apply that torque, making the compressed air system a critical part of the facility, though it largely stays behind the scene.
“Compressed air is our lifeline. Everything here runs on air,” explained Curtis Wood, facilities team supervisor at HAECO Americas (HAECO). “The pneumatic tools, the rivet guns — all of those things are run by compressed air. We need high-volume, quick, very clean air, and we need it to be very stable.”
HAECO Americas Airframe Services provides aircraft maintenance, repair and overhaul (MRO) services to major commercial and military clients. On any given day, one of the multiple hangars at the Greensboro, North Carolina, facility might harbour an aircraft from large commercial airlines, private operators, or the U.S. government. The Greensboro complex is nearly 1,000,000 square feet, with each hangar sprawling over 2 acres under roof.
The rigors and demands of the applications, in conjunction with the sheer scale of the facility, make the compressed air system at HAECO’s Greensboro facility a challenge just to maintain — let alone improve upon. However, Curtis Wood and his team at HAECO managed to do just that, with the help of Patton’s, Inc., a compressed air equipment supplier, and ELGi USA. In an on-going modernization project, the team of engineers has gradually improved reliability of the system and its energy efficiency — all the while adding sophisticated control and data-logging capabilities.
Compressed air is used to power nearly every application. “When you walk around in this place, you hear [compressed] air everywhere,” Wood explained. “It’s all around you.” And, since the mechanics work in confined spaces, the compressed air needs to be treated for contaminants, such as water vapor and oil, making the supply of clean and reliable compressed air paramount for HAECO.
Each of HAECO’s hangars has its own compressed air system, which are under the process of modernization. Ultimately, the final systems will include two ELGi air compressors, an air dryer, a mist eliminator, a storage tank, and a flow controller. While each hangar is unique and demands fluctuate consistently, target pressures remain around 90 psi (8.27 bar), and compressed air flow requirements do not exceed 350 cfm for any hangar.
Tumblr media
Impact of Aerospace Applications on System Dynamics
Compressed air demand fluctuates dramatically at HAECO’s Greensboro plant, largely due to the nature of applications that are unique to aerospace maintenance. For instance, what Wood describes as “blowing down the fuel tank” is a venting procedure that requires about 125 cfm for extended periods of time. When aircraft first arrive at HAECO, their fuel tanks need to be inspected, requiring mechanics to go inside the tank. However, fumes from the tank are toxic and filled with volatile organic compounds (VOCs). To vent the jet fuel fumes out of the tank, compressed air is used to create a Venturi effect that evacuates the tank. Operators use a one-inch air hose to draw off the fumes. The process causes large spikes in compressed air demand for days at a time, and it may occur in multiple hangars simultaneously.
Unique workflows also impact the system dynamics of the compressed air system at HAECO. Air travel increases tremendously around the holidays, making for a temporary lull in work at HAECO. Demand comes surging back immediately afterwards as airplane manufacturers look to get routine maintenance completed during less busy times of the year.
“During the holidays, if you have a plane — it better be in the air,” Wood said. “So we’re really slow the week before Christmas. We run a real low cfm. But the day after Christmas, our cfm will skyrocket when those planes start cycling back in here. We’ll peak out at around January 5, and we’ll be near maximum capacity going forward.”
Workflow also differs hangar to hangar. Although seemingly contradictory, some large aircraft require less compressed air, as the work can move more slowly. Hangars handling other aircraft, such as narrow-body jets, will have much higher compressed air demands over prolonged periods of time.
Tumblr media
Configuration of the Original Compressed Air System
Under consultation with ELGi, the engineers at HAECO have wisely implemented adequate storage and 50-hp variable frequency drive (VFD) air compressors from ELGi to handle the highly fluctuating demand in each hangar. Prior to that, however, the system was quite different.
“Everything here was 75-hp air compressors, and they were set up as load/unload. Then you ran through a dryer, and you had very little storage,” Wood said of the original compressed air system. “Basically, it was a run-all-the-time system. After we studied it with ELGi, we learned a lot about compressed air. We determined that 75 hp was way too much.”
In total, the Greensboro facility had eleven 75-hp air compressors running in load/unload mode. Whenever compressed air demand spiked — due to the fuel venting application or increased workflow — compressors would kick in, and continue running inefficiently for prolonged periods of time.
“One compressor would take the load, and when there was a small spike in demand, another one would kick in but carry very little load, nearly running unloaded,” Wood explained. “And these things would run unloaded for days. They didn’t have VFDs on them, so they weren’t running at brake horsepower proportional to the load. That meant that it’s the same whether it’s running at full load or idling.”
Leveraging Compressed Air Storage to Handle Demand Spikes
With ELGi’s help, HAECO redesigned the system to make better use of compressed air storage, helping each hangar respond to compressed air demand spikes better. Each hangar is a little different in system configuration, but the premise, or the mode of operation, remains the same.
“We’ve basically doubled the number of receivers to handle that [fluctuation] in the system, and then we put flow controllers in there,” Wood explained. “We let the air compressors work to 125 psi (8.6 bar), and then we use a flow controller to modulate the pressure. Each hangar is a little different, but at our most remote point we deliver 90 psi (6.2 bar). Some hangars need 102 psi (8.27 bar) to get 90 psi at the remote end — it just depends on the setup. Then we monitor the cfm that is used, not what is created.”
As Wood explained, each hangar’s compressed air system is a little different: Hangar 1 has about 1900 gallons (254 cubic feet) of storage; Hangar 2 has 1300 gallons (173.7 cubic feet); and Hangar 3 will ultimately have 2000 gallons (267.3 cubic feet) of storage. The goal, according to Wood, is to have 1800 to 2000 gallons of storage in each hangar.
The major difference between each hangar was ceiling height. Hangar 4, for instance, only had enough headroom to install 400-gallon (53.4 cubic feet) receivers. Where Hangars 1, 2 and 3 used dry tanks, Hangar 4 required a wet tank with zero-loss drains. The team at ELGi was helpful in designing that system in particular.
“ELGi actually helped design the system in Hangar 4 because it was very tight,” Wood said. “They were able to help us out with totally different setups and systems. Even though it’s the same concept and design, there are differences in the way we’re delivering compressed air in each building.”
Enhanced Energy Efficiency with ELGi Air Compressors
In conjunction with installing appropriate storage capacity, HAECO is also in the process of replacing each pair of 75-hp air compressors with two 50-hp ELGi air compressors.
“We didn’t need these bigger air compressors, so we were able to downsize to a 50-hp machine,” Wood said. “We found it best to install a 50-hp fixed-speed air compressor, and then put a 50-hp VFD with it. We let the VFD handle the low load, and let the fixed-speed machine do the high load. And probably 25 percent of the time we are running both.”
ELGi at Haeco
In conjunction with installing appropriate storage capacity, HAECO is also in the process of replacing each pair of 75-hp air compressors with two 50-hp ELGi air compressors.
With these changes the electrical load of the plant has dropped substantially. To date, HAECO has retrofitted the compressed air system of two hangars, effectively eliminating 100 hp. Additionally, with proper storage and VFDs, the compressed air system runs much more efficiently: Inclusively, the new VFD machines cost a maximum of $29.39 per hour at full load, and can throttle down to run at $5.87 per hour. In contrast, the original system’s 75-hp air compressors required about $48.00 per hour.
“Basically, by trading two [Brand Xs] for two 50-hp ELGi air compressors, it saved us about $128,000 per year — on the low end,” Wood explained. “That’s easy for our corporate controllers to understand. I can pay for two of these air compressors in the first year.”
Handling Compressor Data
Every hangar has its own Building Management System (BMS), and the new compressed air systems are each tied to their respective BMS. Integrating the new installations into the BMS had its own suite of challenges, but the capabilities to monitor and dictate air compressor performance is quite valuable. One particular challenge was writing the code to convert the air compressor standard values to the metric system used by the BMS.
“That was one of the biggest challenges — converting the data,” Wood said of the air compressor integration. “What that compressor actually shoots out is this huge fraction. We wanted it to read in a standard format. Our programmers went in there, took the data coming out of the ELGi compressor, and learned how to convert it by working with the programmers at ELGi. They helped convert it to data we could use.”
Once the BMS receives and converts the air compressor data, it stores the information at several locations. The metrics are stored on the controller for a week before being sent to the server, where they are stored indefinitely. The record keeping is yielding major operational benefits for HAECO.
“We’re storing that data indefinitely so we can see how things change,” Wood explained. “As we change aircraft, layouts or configurations, we put notes in there. From a business pricing aspect, this is helping us understand what the demand is. Larger aircraft actually require less [compressed air]. The smaller, older airplanes require the most.”
Education from ELGi
Designing an efficient and reliable compressed air system suited for a specific facility is a long and challenging process. Compound that effort with multiple hangars supporting different work requirements, and the process becomes even more difficult. Despite the daunting task, ELGi USA has successfully collaborated with HAECO Americas to dramatically improve the compressed air system at the Greensboro plant.
“The ELGi team helped us overcome some setup issues,” Wood commented. “They were actually able to educate us. We went down to Charlotte, and they broke one of these machines down for us. We learned how to take one of these apart. We knew we were going to do our own service, so we needed to know the same thing the service guys would know — very specific details about how to take these things apart.”
The HAECO plant was one of ELGi’s first customers. The partnership has proved valuable to HAECO from an educational standpoint, and the facilities team is quite pleased with the equipment.
“We’re slowly but surely switching them all to ELGi air compressors,” Wood said. “We like ELGi air compressors because they’re easy to work on. Inside, they’re made in a way that it is easy to maintain. It’s all stainless steel or aluminium. The thing’s going to last a long time, and it can take a lot of abuse.”
HAECO Americas has allotted budgetary resources for more air compressor upgrades in the coming year. Through a partnership with ELGi USA, the compressed air system at the Greensboro plant will continue its modernization process, improving the energy efficiency and putting insightful performance trends on record.

Working Principle of a 20 HP Screw Air Compressor: Uses and Benefits
Tumblr media
A screw air compressor is an essential equipment in various industrial sectors due to its durability, reliability, and efficiency. The 20 hp screw air compressor of reputable screw compressor manufacturers supplies excellent power and performance for medium to large industrial applications. A screw air compressor is a type of rotary compressor air compressor that uses a pair of helical rotors to compress air, providing a constant supply of pressurised air for various tasks. In this article, we will explore how the 20 hp screw air compressors works, its various applications across industries, and the multiple benefits it offers.
How a 20 hp screw air compressor works
The working principle of a screw air compressor is simple and effective. The core components include two helical rotors (screws), an intake valve, a discharge valve, a motor, and a cooling system.
Air intake
The process begins as air enters the compressor through the intake valve. The compression process starts as the air fills the gap between the male and female rotors.
Compression stage
Powered by a 20-horsepower motor, the rotors rotate in opposite directions. As they rotate, the air is trapped between the rotor teeth. The continuous rotation reduces the air volume and compresses it. This compression happens smoothly and evenly due to the precision of the rotors, which minimises energy loss during the process.
Air discharge
Once the air is compressed, it is forced through a discharge valve into a storage tank or directly into the system, depending on the requirement. The relief valve controls compressed air flow, ensuring optimal pressure and backflow control.
Cooling and lubrication
Compression develops heat, which must be controlled to ensure the longevity and efficiency of the compressor. In oil-lubricated screw compressors, oil cools and lubricates the system while providing a minimal gap between the rotors. After compression, the oil is separated from the compressed air before it exits the unit. Oil-free screw compressors are also available for industries requiring contamination-free air.
Applications of a 20 hp screw air compressor
The screw air compressor of reliable screw compressor manufacturers is powered by a 20-horsepower motor, making it suitable for medium to large industrial applications where a constant supply of compressed air is required. These compressors are designed to operate efficiently for long hours and can handle high workloads, making them a popular choice in manufacturing, food processing, automotive, and more. Here are some of its critical applications:
Manufacturing
In manufacturing plants, a 20 hp screw air compressor powers machinery, conveyors, and air tools. Screw compressor manufacturers ensure that air pressure is for assembly, cutting, and finishing, helping maintain product quality and efficiency.
Automotive industry
Screw compressors are essential in automotive plants, where they operate air-powered tools such as wrenches, spray guns, and lifting equipment. They also play a crucial role in tire inflation and assembly line operations.
Food and beverage industry
In food processing, a rotary screw air compressor is used for packaging, filling, and bottling. Reputable screw compressor manufacturers offer oil-free screw compressors to prevent contamination and maintain product purity.
Construction
