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 TSF1 CNG filter is used for fueling stations and dispensers as well as onboard CNG powered vehicles. The filter is mainly installed as prefilter in the media inlet between fueling nozzle and filling hose.
