Direct answer
Air preparation units help pneumatic systems run consistently by filtering compressed air, regulating pressure and providing lubrication where the circuit requires it.
Protect downstream components
Filtered and regulated air can reduce contamination and pressure fluctuation before solenoid valves, cylinders and actuators.
Match the system size
Port size, flow rate, pressure range, filtration grade, drain type and bowl type should match the equipment layout.
Use with complete pneumatic circuits
Air preparation units are often purchased together with solenoid valves, cylinders, tubing and fittings.
