Product Highlights

Further data

Gram cyclone filters of the type ACF-A in all versions is an energy-optimized, compressed-air cleaned filter units.

  • Inlet with downflow, preseparation by cyclone effect as well as optimized filter cleaning ensure lower differential pressure above the filter cartridge.
  • By this longer operating times with less shutdowns as well as lower operating costs (filter material, electricity and compressed-air consumption) are achieved.
  • The air is filtered through vertical standing cartrdige filters with internal core, which optimizes the cleaning effect.

The models are delivered completely assemblied, are raised and connected. All units are equipped with explosion membrane for relief.

Filter sizes:
Type ACF-A is delivered for zone 21/22 and 21/21 in the sizes up to 468m² filter area (filter material G113) and 18 filter cartridges/jet valves.Max. vacuum: 5,000Pa. Is available in the version ACF-T-A with outlet in the top.

Type ACF-V-A is delivered for zone 21/22 and 21/21 in the sizes up to 130m² filter area (filter material G113) and 5 filter cartridges/jet valves. Max. vacuum: 40,000Pa. Is available in the version ACF-T-V-A with outlet in the top.

Type ACF-A-HO prepared for Hôrbiger-valve is delivered for zone 21/22 and 21/21 in the sizes up to 234m² filter area (filter material G113) and 9 filter cartridges/jet valves. Max. vacuum: 5,000Pa. Is available in the version ACF-T-A-HO with outlet in the top.
