This guide provides a technical overview of the WAALPC AF Series Air Filters, models AF1500 (G1/8) and AF2000 (G1/4). The AF Series removes moisture, oil, and solid particles from compressed air using a two-stage process: centrifugal separation and precision mechanical filtration. It features a transparent PE bowl for easy monitoring, a die-cast aluminum body, and a filter cup capacity of 15 CC. Available in 5μm, 25μm, and 40μm filtration grades, the AF Series operates at a maximum pressure of 0.95 MPa and a temperature range of 5–60°C. Applications include general manufacturing, automotive, electronics, and packaging. Installation and maintenance tips are also provided to ensure optimal performance and longevity. Read More

This guide provides a comprehensive overview of the WAALPC AFR Series Filter Regulators, including models AFR1500 (G1/8) and AFR2000 (G1/4). The AFR Series combines high-efficiency filtration and precise pressure regulation into a single, compact unit, saving installation space and reducing leak points. It explains the two-stage working principle: centrifugal separation and filter element capture for contaminant removal, followed by a diaphragm force-balance mechanism for stable pressure control. Key features include a press-in self-locking adjustment knob, a transparent PE bowl for easy monitoring, an integrated pressure gauge port, and multiple filtration options (5μm, 25μm, 40μm). Technical specifications cover a pressure regulating range of 0.05–0.85 MPa (with a low-pressure 0.02–0.83 MPa option), maximum operating pressure of 0.95 MPa, and an operating temperature range of 5–60°C. The guide also covers application scenarios in electronics, packaging, food processing. Read More
