Modern compressors for gas recovery and compression are equipped with gas seals. These seals work with a sealing gas that isolates the chamber between the compressor oil or the working chamber from the outside atmosphere. The higher the operational pressure the higher the demands are on the dimensional tolerances and surface smoothness of all the components involved. In addition to these criteria, the requirements on the seal gas quality with regard to any particles it might carry also increase. Our filters ensure the functionality and durability of gas seals even at high operational pressures. This also applies to the use of gas seals for isolating the contents of storage tanks from the atmosphere. Particle separation also includes separation of water and oil droplets, which is also an important precondition for further gas drying.
