increases service life of downstream fittings and equipment
high flow rate - owing to flow maximising design
especially for O2 with bronze filter, meets all requirements of EIGA guidelines
with condensate drain
change of filter possible while installed
every gas filter 100% tested
72 X 205 mm, approx. 3 kg
WITT gas filter for GOX : Best practices in Safety, with maximum Operability.
In addition to removing contaminants, WITT’s Filter 77 – O2 drains out condensate, protects downstream
equipment and extends service life. All designed to meet the Best practices in Safety, with maximum Operability.
Description :
Bronze (Cu89/Sn11) 50μ filter element
O-Ring Elastomer FKM (FKM 938)
-30 °C to +60 °C
Up to 40 barg
Connections G 3/4 F
Length 205 mm, diameter 72 mm, mass 3.03 kg
Type 077-010
Meeting the Best Practices in Safety :
Meets all the requirements of EIGA Guideline IGC Doc 13/12/E “Oxygen Pipeline and Piping Systems“
Certification by BAM (German Federal Institute for Materials Research and Testing) for O2 service
Pre-cleaned to EIGA Guideline IGC Doc 13/12/E, and ready for O2
Withstands maximum line pressure (40 barg) even if it becomes clogged
No velocity limitation, including during commissioning “blow-out” testing
Not subject to a minimum thickness requirement (per Appendix D of EIGA Guideline IGC Doc 13/12/E).
With maximum Operability :
Reliable filtering performance increases service life of downstream fittings and equipment
Condensate can be collected and removed using condensate drain
Change of filter element possible while installed, due to user-friendly design
High flowrates owing to its flow maximising design (please see flow curves overleaf)
Easy to install
Easy to maintain - the condensate should be drained at regular intervals, and the filter element should be checked regularly and replaced if necessary in accordance with Appendix F of EIGA Guideline IGC Doc 13/12/E.
