WITT Gas Filter 77

The WITT Gas Filter 77 is designed to be suitable for the filtration of process gases used in the food industry.

Even with high-purity gases, particle ingress cannot be completely ruled out in practical operation — particles may originate, for example, from molecular sieve materials in air separation plants, from corrosion residues in gas cylinders, and from pipework, valves and fittings that release particles during installation or operation.

Gas Filter 77 is designed to remove such particles from the gas supply and protects downstream components such as valves, pressure regulators and gas mixers from malfunctions and premature wear.

For use in food industry applications, WITT can provide a declaration of conformity in accordance with EU Framework Regulation (EC) No 1935/2004. The gas filters are manufactured to stringent cleanliness requirements and are also subjected to particle testing. In addition, WITT is certified to DIN EN ISO 22000 for food safety management systems.

The gas filter is suitable for a wide range of technical gases and is available in various versions. All versions are cleaned for O2 service, per EIGA, AIGA und CGA requirements. Different filter fineness grades and variants made from bronze or stainless steel allow the filter to be tailored to specific applications and requirements.
