AR High-Flow Pilot-Operated Air Regulator for Large Compressed-Air Systems 2026-07-10
The WAALPC AR Series is a high-flow, pilot-operated air pressure regulator designed for large industrial compressed-air systems. Available in AR825-15, AR925-20 and AR1200-30 models, the series provides G1½, G2 and G3 port sizes with rated flow capacities of 12,000, 20,000 and 28,000 L/min. Its internal pilot-operated relieving design helps maintain stable downstream pressure when air demand changes, making it suitable for central compressed-air lines, automated production equipment, large pneumatic cylinders, packaging machinery, painting systems, blow-off applications and industrial air-distribution networks. The standard regulating range is 0.05–0.85 MPa, with a maximum operating pressure of 1.0 MPa and an operating temperature range of –5°C to 60°C. A 1/4-inch pressure-gauge port allows convenient monitoring and adjustment of outlet pressure.
