This model provides the most reserve air available in an electric wheelbarrow, with a 20 Gallon ASME tank--more than twice the storage capacity of the standard twin tank. Capable of running on a 20 Amp breaker, this unit will deliver 7.3 CFM, doubling the output of many direct-drive units. Additionally, the low RPM pump and motor combine for quiet operation. Battle tested contractor tough? There's only one way to find out. Get it dirty, run it hot and don't let up - just like a contractor. That's how they're used, so that's how they're tested. Engines, pumps, motors, switches - every component of every ROLAIR compressor is battle-tested both in the field and at our Wisconsin factory. You have our guarantee that your ROLAIR compressor is ready to roll on day one, no excuses.
