The Q3 Pro™ model turbine is powered by a high-performance, 3-stage double ball bearing, single speed, bypass motor that produces over 100cfm (unrestricted) at 5psi. This motor is a real workhorse and is the most powerful in its class. Three stage means that 3 fans are used to develop air propulsion. The Q3 Pro™ is designed for spraying all types of coatings including lacquers, enamels, oil-based paints, water-based coatings and occasional latex spraying. The system is perfect for cabinetmakers, furniture refinishers and most trades. Spray cabinets, furniture, autos, pianos – in fact, anything wood or metal.
