Gas Filter 77

WITT gas filters for reliable protection against contamination and condensate.

Benefits:

• ultra-fine filtering out of mechanical impurities through bronze or stainless steel filter inserts
• broad range of uses – compatible with many technical gases
• filter inserts in stainless steel with a filtering fineness of approx. 0,5 µm, approx. 10 µm or approx. 40 mµ
• filter inserts in bronze especially for O2 with a filtering fineness of 5 µm or 50 mµ, according to EIGA
• 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
• easy to install thanks to large choice of connections
• reliable filtering performance increases service life of downstream fittings and equipment
• withstands maximum line pressure (50 bar) even if it becomes clogged

Operation / Usage:

• particularly well suited to use in laser systems
• Gas filter model 77 is designed for installation in pipelines
• 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 regularly and replaced if necessary
