An air preparation unit works by filtering, regulating, and lubricating compressed air before it enters a pneumatic system, ensuring clean, properly pressurized, and lubricated air for reliable operation.
Air system treatment(FRL) refers to the process of filtering, regulating, and lubricating compressed air to ensure it meets the required quality for pneumatic applications. FRL removes contaminants, controls pressure, and provides necessary lubrication to extend the lifespan of pneumatic components.
Compressed air coming directly from an air compressor is typically unclean, humid, and unstable, making it unsuitable for direct use in pneumatic equipment.
The compressed air directly from the air compressor is very unclean and unstable, and cannot be directly used in pneumatic equipment.The air source treatment unit is the control mechanism for compressed air entering downstream control and execution components. The air source treatment unit regulates and prepares compressed air before it enters downstream valves, actuators, and cylinders. Without proper air preparation, the following issues may occur:
◆ Accelerated wear of seals and piston rods
◆ Valve sticking or sluggish operation
◆ Significantly shortened cylinder life
◆ Unstable cylinder thrust
To ensure reliable pneumatic system performance, an air source treatment system is essential.
An Air Source Treatment Unit, also known as an FRL unit, is a combined pneumatic device used for compressed air filtration, regulation, and lubrication. It receives air from the compressor and performs the following preparation steps:
Filtration – removing particles, moisture, and contaminants.
Regulation – stabilizing air pressure.
Lubrication – providing micro-oil mist for smooth component operation.
Pneumatic Air Filter (F)
Air Pressure Regulator (R)
Air Lubricator (L)
Because they are standardly used as a combined unit, the system is called an FRL (Filter + Regulator + Lubricator).
An air preparation unit works by filtering, regulating, and lubricating compressed air before it enters a pneumatic system, ensuring clean, properly pressurized, and lubricated air for reliable operation.
Air preparation combination unit plays an extremely important role in pneumatic systems by ensuring the compressed air meets the cleanliness, pressure stability, and lubrication requirements needed for cylinders and valves to operate efficiently.
◆ Pneumatic Filter(F)
This pneumatic filter removes solid particles, moisture, and impurities from compressed air. A built-in oil-water separator and automatic drain valve prevent water from entering the pneumatic circuit, thus protecting valves, cylinders, and actuators.
◆ Air Pressure Regulator(R)
This unit is primarily responsible for maintaining a stable and precise output pressure for the system, ensuring consistent cylinder thrust, and preventing damage caused by pressure fluctuations.
◆ Lubricator(L)
This last component primarily sprays a controlled amount of lubrication oil into the air stream to reduce friction and increase the service life of pneumatic components.
The air treatment unit FRL reduces installation space, simplifies piping,and improves reliability by combining three essential elements into one compact system.
