Gas filters for protection against condensation

Witt Gas markets a range of gas filters to provide protection against flammable and non-flammable gas contamination and condensation, with BAM approval for use with acetylene in many heavy industries

Witt Gas Techniques, the Warrington based gas safety, control, mixing and analysis equipment supplier, now markets a range of gas filters to provide protection against flammable and non-flammable gas contamination and condensation, with BAM approval for use with acetylene in many industries - including shipbuilding, large fabrication shops, steel mills and other heavy industries.

The 77 and 625 filters are designed for use in gas supply pipelines and the 622 filter is designed for use at outlet points in gas pipelines.

Features include ultrafine filtering of mechanical impurities using nickel chromium steel filter inserts: the filters can be changed whilst in situ, they all have high flow rates, and condensation can be collected and removed using a condensation drain on the 77 and 625 filters.

With acetylene, the maximum working pressure on all three filters is 1.5 bar, for other fuel gases it is 16 bar.

For compressed air using the 622 and 625 filters it is 16 bar.

On the 77 filter the maximum working pressure using compressed air or pure oxygen is 40 bar.

These filters are easy to install as they are can be ordered with a large choice of connections, whilst their filtering performance will improve the service life of downstream fittings and equipment.

Witt Gas recommend to users that the condensation should be drained at regular intervals and the filter inserts should be checked in rotation and replaced if necessary.
