20 Gallon Oil-Free Air Compressor, Compact & Lightweight Design, Hassle-Free Operation, DOBA-AC20L

DOBA-AC20L delivers reliable, high-capacity performance for a wide range of pneumatic applications. Powered by a 3 kW oil-free motor running at 1680 r/min, it generates up to 10.6 SCFM at 90 PSI—ideal for operating nail guns, impact wrenches, spray guns, pneumatic screwdrivers, tire inflation, auto repair tasks, spray painting, and wood-working nailers. Its 20-gallon tank ensures consistent air delivery and minimizes run-cycles, making it a workhorse for both DIY enthusiasts and professional workshops.

Equipped with a tube-and-cylinder intake system, the DOBA-AC20L speeds up pressurization while reducing wear. The intake pipe features high-temperature-resistant silicone reinforced with stainless-steel braided mesh, offering dual protection against damage and corrosion. Despite its powerful output, the compressor maintains a remarkably low noise level of 78 dB thanks to a three-piece silencer assembly—thickened muffler cover, rubber muffler pipe, and filter cotton—to dampen sound and prevent fine dust ingress. Safety features include a large cooling fan, automatic overheat protection to guard against motor damage, and automatic shutoff or pressure relief if current or tank pressure exceeds safe limits.

Built for durability, the DOBA-AC20L’s 20-gallon tank and frame are constructed using a three-layer process: a rust- and wear-resistant base layer, a plastic powder coating, and a Q235B structural-steel core to withstand high bearing pressure while preventing leaks and corrosion. Seamless welding ensures a robust, explosion-resistant structure. Whether you’re a contractor running nailers on-site, a mechanic inflating tires and powering impact wrenches, or a woodworker using spray guns and pneumatic tools, this compressor combines quiet operation, advanced safety protections, and rugged construction to meet demanding workshop and job-site needs.
