20 Gallon Air Compressor
Our 3KW oil-free motor drives the compressor up to a speed of 1680 r/min and delivers 10.6 SCFM @ 90 PSI. Ideal for supporting a variety of pneumatic and air tools—such as nail guns, impact wrenches, spray guns, pneumatic screwdrivers—and perfect for tire inflation, auto repair, spray painting, and woodwork nailing.
Fast and Efficient Inflation
This oil-free air compressor adopts a tube-and-cylinder intake design, effectively saving time and effort. The intake pipe is made of high-temperature–resistant silicone with a stainless-steel braided mesh overlay, providing double protection to reduce damage and corrosion.
All the Power, Without the Noise
Our ultra-quiet air compressor operates at just 78 dB, thanks to a high-quality silencer. Each muffler consists of a thickened muffler cover, a rubber muffler pipe, and filter cotton. This combination not only reduces noise but also prevents fine dust from entering the system.
Designed to Withstand
The electrical air compressor features a three-layer construction: a rust- and wear-resistant outer layer, a plastic powder adhesion layer, and a Q235B structural steel core, ensuring durability and ultimate rust resistance. Its large bearing pressure and seamless welding construction provide the strength needed to withstand explosions and prevent leakages.
Security Comes First
The air compressor tank is equipped with a large cooling fan and automatic overheating protection to prevent damage. Additionally, if the current or storage pressure becomes too high, the compressor will automatically shut off or engage pressure relief protection.

Product Description
Product Description
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.
