WEH® Coalescing Filter TSF2 CNG - Product family

for CNG fueling stations / vehicles (ECE) 

Clean, filtered gases are essential to guarantee the proper function of components for vehicles and fueling stations when refueling with natural gas.

The WEH® TSF2 CNG coalescing filter was developed to remove particles from the gas flow.

When filtering the gas flow, the coalescing filter reliably removes contaminants such as oil, water and dirt particles which are contained in the gas. This contamination is isolated by the coalescing filter.

Natural gas flows through the filter, whereas contaminants such as oil, water and other aerosols coalesce, and drop into the sump of the filter, where they are separated into a drain port.

The filters are easy to maintain and can be installed onboard vehicles and in fueling stations at any time.
