Air Filters

Cleaner Compressed Air for Reliable Pneumatic Equipment

Inline compressed air filters remove solid contamination and entrained material before it reaches valves, cylinders, regulators and other pneumatic equipment. The NAF series can be installed as a standalone filter or close-coupled with a pressure regulator and lubricator to form a modular FRL assembly.

A quick-connect bowl arrangement helps simplify filter-element service. The source range lists a 25 micron element with 5 and 40 micron options, available in sintered bronze or polyethylene depending on the required configuration.

Frequently Asked Questions

What does an inline compressed air filter do?

It removes particulate contamination and entrained material from the air stream before the air reaches downstream pneumatic equipment.

Can the NAF filter be used by itself?

Yes. The source description states that the filter can be installed alone or used with a regulator and lubricator.

What micron elements are listed?

The source range lists 25 micron, with 5 and 40 micron options.

What filter-element materials are available?

The source description lists sintered bronze and polyethylene element options.

Can this filter be assembled into an FRL?

Yes. It can be close-coupled with compatible pressure regulators and airline lubricators using the appropriate assembly hardware.

Why is compressed air filtration important?

Filtration helps reduce contamination reaching valves, cylinders, seals and instrumentation, supporting more reliable pneumatic operation.

When should a filter element be replaced?

Inspect the element routinely and replace it when contamination, damage or excessive pressure drop indicates service is required.

How do I choose the correct air filter?

Consider port size, flow demand, filtration grade, operating pressure, bowl configuration and acceptable pressure drop.
