The two-stage splash lubricated QT piston air compressor models are designed to deliver higher volumes of air while also consuming less energy. The special valve design provides the highest possible volumetric efficiency and features super-strong stainless steel valves. The balanced counter-weighted crankshaft ensures smooth operation and fewer maintenance headaches. The cast iron construction also assures a long compressor lifespan. As with the QP line, the QT is available in Pro Unit and Max Unit options.
