CKD M-Series standard white oil mist filters for circuits requiring oil-free or odorless air — instrumentation, measurement, precision manufacturing, food, and pharmaceutical applications. Available in three mantle types: M-type (0.01 μm nominal, ≤0.01 mg/m³ residual oil), S-type (0.3 μm, ≤0.5 mg/m³), and X-type (activated charcoal deodorization, ≤0.003 mg/m³). Port sizes from Rc1/8 to Rc1 across M1000 through M8000-W models. Options include differential pressure indicator, differential pressure switch, auto-drain, and metal bowls.
