Gas filters

Filters for gas pipelines with very high holding capacity of dust and impurities, suitable for protection of devices installed downstream.

The filter cartridge is a steel supported frame covered with a high performance nonwoven made of polypropylene fibres, which satisfy the stringent requirements of Fire Class F1 according to DIN 53438 and thus are self-extinguishing.

Inlet and outlet pressure chambers can be provided with gauges, to connect a gas differential pressure switch to monitor the pressure difference.

When the dust storage capacity is exceeded, the filter element must be replaced.

FGS1-2 models are provided with a washable mesh filter cartridge.
