DF Filter is a filter unit, it is an ecnomic replacement of FESTO D series FRL LF filter made in China, it saves space and require less piping. it is a reliable compressed air preparation for applications in uncritical environments, freely combinable within the NTA D series FRL. DF 200 to DF600 have a metal bow guard, port thread M5, 1/8'', 1/4'', 3/8'', 1/2'', 3/4'', 1''. Working pressure from 0.15MPa to 1.2MPa, max input air pressure at 1.6MPa. Max flowrate from 500L/min to 11500L/min. Grade of filtration 40 µm and 5 µm optional. Differential pressure drain and auto drain are available, special guide structure makes the flowing gas spin properly to seperate the water from compressed air and filter solid particals efficiently.
