Equipped with a ULTRA-QUIET 1HP 6.3 Gallon Tank, this air compressor and tire inflator runs at a lower RPM (1500) for extended motor and pump life. The Brushless motor and Oil-free dual-piston pump design ensure maintenance-free operation, while the 1/4" inch NPT Quick Connect Coupler and Mechanical Pressure Gauge allow for easy monitoring of the PSI range (MAX 135psi). With a high efficient Electric Motor System and a mere 60dB of sound during peak operation, this unit provides consistent performance and fast inflation. Safety features include a Safety Valve for quick depressurization and a Drain Valve to prevent moisture build up and corrosion. The commercial-grade rubber suction cups and Ergonomic Grip Carry Handle make it easy to move and transport, but it is not suitable for heavy-duty truck tires.
