The AirCat 1in. Heavy-Duty Aluminum Impact Wrench delivers all the power with half the noise! This twin hammer wrench is designed for light-to-medium duty applications. Patented tuned exhaust muffler technology allows discharged air to pass without developing back pressure, thus retaining more power, while significantly reducing noise. Through-the-handle exhaust uses patented internal muffler/filter which reduces hazards from breathing exhausted air particulates, eliminates blow-by into operators eyes and lungs, as well as reducing noise. Ergonomically engineered handle relieves stress and fatigue on operators hands, wrists and arms. Handle offers better overall distribution of weight for a balanced tool and provides a comfortable grip that makes it easier to use for prolonged periods of time.
