FST-Compressed air filters – durable, versatile, economical

Whether it is coarse filters, fine filters or ultra-fine filters: compressed air filters are an elementary component in compressed air treatment. Step by step, they remove all kinds of contaminants, both solid and liquid. According to the motto "As much as necessary, as little as possible", our experts design economical and safe systems. Several filter elements at the same time ensure the necessary compressed air quality along the treatment chain – for all purity classes according to ISO 8573-1.

Our products

FST compressed air filters ensure the purity of your compressed air - reliably and highly efficiently. In our standard portfolio you will find volume flows up to 30,000 m³/h and operating pressures up to 350 bar. These include threaded filters, flange filters, high-pressure filters, process filters, or even activated carbon filters.

A wide range of compressed air filters step by step remove all kinds of solid and liquid contaminants: from coarse contaminants, such as rust and abrasion, to oil droplets and dust particles, through to the finest oil mist and micro dust. In addition, filter units with activated carbon remove unpleasant odours and oil vapors. Specialised sterile filters even clean the compressed air of viruses and bacteria.

Filter housings for larger volume flows, made of the highest quality stainless steel or with other connections can be manufactured individually on request. Our specialists for compressed air filtration and filter units will advise you competently and in a solution-oriented manner.

6 advantages that are distinctive for FST compressed air filters


Easy maintenance

The FST "1-person-simple-service-concept" applies to all filter housings. What does this mean? A complete service, even on the largest compressed air filter, can be carried out by a single person - without special tools and without additional help.



High-quality compressed air filter elements

Before we ship our filter housings, each one is thoroughly inspected and pressure tested. In this way, we can ensure that the housing is tight and that our filter elements have a reliably high retention capacity at low differential pressure.


Certified to European & International Standards

Each of our filter housings is certified in accordance with the Pressure Equipment Directive (PED) 2014/68/EU. In addition, our compressed air filters and filter elements are approved according to other international standards and are therefore 100 % safe to use.


Long service life

We use only high-quality materials for our robust filter housing. Double surface protection on the inside and outside as well as seamless passivation on the inside ensure a long service life as standard.


Universal use

Each of our compressed air filter housings is equipped with a standardised connection for condensate drainage. We supply the FCA, FWS, FMA, and FMS series with connections for differential pressure monitoring as standard.


Wide range of accessories

We offer a wide range of accessories and numerous retrofit solutions for all FST filter housings. These include, among others, differential pressure gauges with potential-free contact, humidity or oil vapor indicators.
