The Rolair 2 HP (115V), 4.2 CFM@90PSI, 3.2 Gallon, Quiet Cart Compressor with Tool Box (VT20TB) is a conveniently lightweight tool that is capable of powering heavy duty tasks. It boasts a cast-iron cylinder, along with stainless steel reed valves and splash lubrication that ensure longer life. This is the first ROLAIR model to combine a low-noise and low-speed pump with a higher CFM output. This 4.2 CFM compressor delivers as much air as most high-speed pumps, while running at only 1700 RPM it drastically reduces the noise commonly associated with jobsite air compressors. For added benefit, it comes with a built-in tool box for convenient on the job storage.
