The Vevor air compressor filter regulator combines 2-stage precision filtration, stable pressure regulation, and a desiccant dryer to deliver clean, dry compressed air. It uses a 5 μm brass filter element, 0.3 μm sponge filter, and 0.1 μm desiccant drying stage to help remove moisture, particles, and impurities. An auto drainage system with built-in float switch helps reduce maintenance and the risk of missed draining. Its durable aluminum alloy body is built for home and industrial applications including auto repair, spray painting, and general shop use. The 3/4" NPT connection fits most compatible air compressor setups.
