Technical Data Sheet Page 1 of 3 Filter Housing HD High Pressure The HD high pressure filter housings are designed for the purification of compressed air and gases. Due to the modular design of the housings different filter elements can be used. Product description: HD high pressure housings are designed for the purification of compressed air and gases in an industrial operation. The housings made out of two parts offer, due to an optimized construction, low differential pressures at high flow rates. A multitude of housings with different connections, allow to match the requirements of the application, e. g. the compressor size. In this product series are 8 different housings available ranging from a volume flow of 30 m3/h to 720 m3/h, in the pressure stages PN 25 to PN 400 (related to 7 bar (g) and 20°C). The HD high pressure housings conforms to the requirements of the European directive 97/23/EC for pressure vessels.
