NTA AF Filter is a filter unit, it is an ecnomic replacement of SMC A series FRL AF 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 A series FRL. AF 2000 to AF5000 have a metal bow guard, port thread M5, 1/8'', 1/4'', 3/8'', 1/2'', 3/4'', 1''. Working pressure from 0.05MPa to 1.0MPa, max input air pressure at 1.5MPa. Grade of filtration 40 µm and 5 µm optional. Manual 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.
