FS 641

Gas filter separator FS 641

The FS 641 is a two-stage filter separator, where the first stage is an axial cyclone or a multicyclone bundle and the second stage consists of filter elements. Cellulose or glass fiber filter elements are usually employed, but other filtering media are also available. Depending on the size of the filter separator, one or more filter columns can be present.
The FS 641 filter separators can be used in the natural gas regulating and metering stations, gas delivery stations, gas dehydration units, compressor stations, etc., providing the separation of liquid fractions and solid contaminants for the protection of pipelines, equipment and devices which could be damaged because of particle-contaminated gas
