Designed for complete system protection in low - pressure oxygen distribution lines. Service experience has shown that the biggest cause of component failure is attributable to particulate contamination. The entrance of these contaminates is primarily due to poor plumbing practices and failure to purge the lines once installed. Complete system protection with flow rates up to 400 LPM is possible with these units. Pore size versions in 11 and 30 micron (nominal) are available in various fitting types for 5/16 O.D. tube sizes (oxygen standard). The filter element is a woven stainless steel sintered wire cloth, which is replaceable. The filters when installed should be at or near the end of hard plumbed lines.
