Contaminants in the gas flow can enter the vehicle‘s storage tank during refueling. These dirt particles in the natural gas fuel may cause damage to the sealing components.
WEH, therefore, offers CNG filter for clean natural gas. Solid particles are captured reliably.
The filter element can be removed and is re-usable after having been cleaned.
The TSF4 CNG filter is mainly used for onboard CNG powered vehicles, but can also be used for fueling stations and dispensers.
The TSF4 CNG round filter is available with double ferrule fitting or female thread on both sides or external and female thread. TSF4 CNG T-filter has been specially designed for use in CNG buses and trucks. The filter can be removed for cleaning purposes without tedious unscrewing of the media lines.
