High filtering capacity gas filters

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

The filter cartridge is a self-extinguishing, steel-supported frame covered with a high-performance nonwoven made of polypropylene fibers, satisfying the requirements of Fire Class F1 according to DIN 53438.

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

Replace the filter when the dust storage is at capacity. FGS1-2 models come with a washable mesh filter cartridge.
