Description
WFIT welded stainless steel filters with threaded connections are designed for protection of the downstream compressed air system and equipment against defects and other failures. They are used for filtration of compressed air as well as many other gasses where the risk for corrosion is very high or where stainless steel housing is required. To meet the required gas quality appropriate filter element must be installed into filter housing. Required compressed air quality according to standard ISO 8571-1 can be achieved with 8 different grades of filter elements (PI, PIW, PN, PP, PR, PM, PS and PA). Optional external condensate drains should be used for efficient condensate draining from filter housing.
Operating Pressure: 16 (12) bar
