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. Read More

This comprehensive guide provides an in-depth overview of the WAALPC HDA Series modular air source treatment units — a family of pneumatic components designed to deliver clean, regulated, and well-lubricated compressed air for demanding industrial applications. The HDA Series includes HDAW modular filter-regulators for oil-free FR configurations, HDAR standalone pressure regulators for precise pressure control, HDAL oil mist lubricators for efficient component lubrication, and HDAF standalone filters. All models feature modular design with compact structure, good shock resistance, and transparent polycarbonate covers for 360° visual confirmation of internal conditions. Technical specifications cover maximum working pressure (1.0 MPa), temperature range (5–60°C), filtration precision (25μm standard, 5μm and 40μm optional), port sizes (1/8" to 1/2"), and pressure regulating range (0.05–0.85 MPa). The article explains working principles including centrifugal filtration, diaphragm-based pr Read More
