Cam GT Box Type Green
for turbo machinery

CamGT Box Type Green Filter

Application Areas

  • Air inlets for turbine equipment
  • Axial/reciprocating compressors
  • Off-shore and coastal installations
  • Installations with recurrent high humidity

Patent Pending Construction

Cam GT Box Type Green's large filter surface is based on Camfil Farr's patent pending construction featuring vertical pleats, hot melt separators and polyurethane seal. The filter media packs are reinforced with a strong backing screen and enclosed in a robust plastic frame to withstand severe pressure fluctuations encountered in turbo machinery applications. With the backing screen and the moulded polyurethane gasket permanently fixed to the filter frame, the filter installation simplified with limited risk for filter media damage and leakages.

High Humidity Conditions

Cam GT Box Type Green's unique construction allows trapped water to drain freely from the filter during operation, thus avoiding re-entry of dissolved impurities and maintaining low pressure drop under high humidity conditions.

Key Features

  • Offers optimum engine protection
  • low pressure drop also in ”wet” conditions
  • improves overall filter economy
  • increases service life
  • heavy duty, compact construction
  • easy mounting
  • completely incinerable
  • excellent burst pressure performance
Camfil Farr ́s gas turbine filters are tested at VTT*, in accordance with CEN EN 779. Burst pressure drop tests have been conducted at VTT with excellent results. * independent test institute
