WITT gas filters for reliable protection against contamination and condensate

Advantages

• ultra fine filtering out of mechanical impurities through nickel chromium steel filter inserts

• broad range of uses - compatible with many technical gases (e.g. BAM approval for acetylene)

• change of filter possible while installed due to user-friendly design

• high flowrate thanks to flow maximising design

• condensate can be collected and removed using condensate drain (models 77 and 625)

• easy to install thanks to large choice of connections

• reliable filtering performance increases service life of downstream fittings and equipment

Use

Gas filter models 77 and 625 are designed for installation in pipelines. Model 622 is used at outlet points.

The gas purifiers with condensate drain must be installed vertically.

Maintenance

The condensate should be drained at regular intervals; the filter inserts must be checked in rotation and replaced if necessary.
