The Vevor air compressor filter regulator combo is designed to deliver cleaner, drier compressed air with stable pressure regulation for demanding shop and garage use. Its 3-stage filtration system combines 25 μm, 5 μm, and 0.3 μm filter elements with oil-water separation to help remove moisture, particles, and impurities. A semi-auto drain design automatically discharges collected water after shutdown to reduce maintenance issues. The aluminum alloy body provides durable resistance to pressure, corrosion, and impact. This unit is well suited for auto repair, spray painting, home improvement, and other compressed air applications.
