40u Air Filter Regulator With Drain Cup

Compact air treatment unit sized at 21 x 7.3 x 6.4 cm (8.27 x 2.87 x 2.52 inches), weight 446 g. Features G1/4" ports, G1/8" gauge port, 40 µm filter accuracy, and a 60 cc transparent drain cup for visual oil monitoring. Pressure regulation range: 0.15–0.9 MPa (max 1.0 MPa); proof pressure: 15 kgf/cm²; operating temperature: 5–60 °C. Designed specifically for compressed air — not for gases or liquids. Its self-locking pressure-entry design ensures set-point stability, while low-pressure-loss internals support system efficiency. High-efficiency water separation protects downstream components. The small horizontal footprint makes it suitable for dense control cabinets or inline mounting on narrow piping runs. Frequently applied in printing press air controls, textile loom actuators, pharmaceutical packaging machines and vocational training rigs — all requiring visible diagnostics, space efficiency and stable air delivery.
