WEH® Filter TSF4 Gas, for mounting into gas mixing plants, for inert/flammable gases, 40 micron, max. 420 bar


Filter for use with inert gases and for mounting into gas mixing plants

Clean, filtered gases are a basic requirement in order to ensure the proper functioning of individual components in gas mixing plants.

Specifically, seals can be damaged by dirt particles in the media flow. The WEH® TSF4 particle filter has been developed to clean the media flows from these components. The TSF4 protects the downstream components of your systems safely and reliably.

The WEH® Gas Filters TSF4 is particularly useful in gas filling systems for inert gases like argon and nitrogen. The gas flows through the filter and the filter retains any dirt particles contained in the gas.

The TSF4 is suitable for high pressure applications and is particularly easy to maintain. The wire filter insert can be removed for cleaning purposes without removing the media lines.
