Elektrogas Cartridge Gas Filter FG Series

Features:

  • The filters are made of aluminum alloy die-cast, with a wide range for inlet/outlet connections from DN15 up to DN 300.
  • Suitable for natural gas, town gas, LPG (gaseous) and air. On request the filters can be provided with special seals suitable for aggressive gases.
  • The incorporated filtering cartridge is a steel support frame covered with a double-layer high performance nonwoven made of polyolefine fibers, which satisfy the stringent requirements of Fire Class F1 according to DIN 53438 and are thus self-extinguishing.
  • Considering the same connection, the FGS are smaller models of FG filters: the body is more compact with a reduced filtering surface.
  • FGS1-FGS2 models are provided with a mesh filter cartridge.
  • FG98-FG910-FG912 models are provided with a 2-stage single-layer filtering cartridge.
  • Provided with pressure gauges for both inlet and outlet chamber (optional for threaded models).
  • All components are designed to withstand any mechanical, chemical and thermal condition occurring during typical service. Effective impregnation and surface treatments have been used to improve mechanical sturdiness, sealing and resistance to corrosion of the components.
  • Filters are 100% tested by computerized testing machineries and are fully warranted.
