Compressed air filtration
Products · Compressed air

Compressed air,
to the class you need.

Water, oil aerosol, oil vapour, particulate — out, down to ISO 8573-1 Class 1 and on to sterile. Tell us what has to come out and we'll point you at the grade. No catalogue to wade through.

The selector

What do you need to remove?

Pick the contaminant — it takes you straight to the right element. The bar runs coarsest on the left to finest on the right.

Got the grade?
Now size the train.

Enter your flow and pressure — the tool returns the housing, how many elements, and the pressure drop across the train. It even sequences the stages (FF → MF → SMF → AK) for the class you set.
