[SMC] — AF20-D Modular Air Filter
Family ID: SMC-AF20-D
SMC modular pneumatic air filter (clean/low-particle spec). Body size 20, port size: 1/8, 1/4. Filter rating: 5 μm. Max working pressure 1.0 MPa, proof pressure 1.5 MPa. Operating temperature: -5 to 60°C. Mass: 0.10 kg. Threads: Rc / NPT / G. Drain options: manual or N.C. auto drain (N.O. not supported on size 20 due to risk of leakage). Mounting option: bracket. Polycarbonate case (case guard standard on size 30+). Other options (alternative case materials including metal/nylon/level-gauge variants, clogging indicator L on size 40, drain port variants J/W, reverse flow direction, psi units) available on request.
