Gas Filter Separator

The GFS Series Gas Filter Separator removes moisture, liquid mists, aerosol and contaminants from hydrocarbon gases, including natural gas, propane, butane and methane, using a three-stage design. The first stage removes gross water by impingement on cartridge stools. The second stage coalesces water using cartridges, with particulate removal down to 0.5 micron. During the third stage, a stainless steel vane mist eliminator removes any remaining moisture. Water collects in the sump to be purged from the system, and clean, dry gas passes through the outlet. The GFS is ideal for use in a wide range of applications, including chemical/petrochemical/natural gas plants, pipelines, refineries, compressor and metering/regulation stations, and power generation plants.
