Product Description

The ARO Super Duty Series Coalescing Filter (MPN F45581-311) is a compressed air filter with 1 1/2 in NPT ports, a 0.01 micron filtration rating, a maximum flow capacity of 1,400 cfm, and a maximum operating pressure of 250 psi.

Frequently Asked Questions

What is the ARO Super Duty Series Coalescing Filter used for?

The ARO Super Duty Series Coalescing Filter (F45581-311) removes oil aerosols, water droplets, and solid particles down to 0.01 micron from compressed air systems. It is used in industrial pneumatic circuits, spray painting, instrumentation, and food processing where high-purity air is required to protect downstream equipment and product quality.

What are the specifications of the ARO F45581-311 coalescing filter?

The ARO F45581-311 is a Super Duty Series coalescing filter with 1 1/2 in NPT ports, a 0.01 micron filtration rating, a maximum flow capacity of 1,400 cfm, and a maximum operating pressure of 250 psi. It is designed for high-flow compressed air systems requiring fine particulate and aerosol removal.

Where to buy the ARO F45581-311 coalescing filter worldwide?
