5.0 out of 5 starsPowerful even at low air pressure

I bought this to help in replacing the axle, struts, and control arms of a 2009 Mazda 3. I have a Fini 150psi, six gallon compressor. I used a ten foot, 3/8" hose with high flow (type V) fittings. Pressure at the gun was 60psi (measured with a gauge), but the 1150 easiliy loosened the 200 ft/lb axle nut (admittedly, the threads were clean and rust free). The compressor did not have to restart. Theorizing that the regulator was restrictive, I used a tee (1/4" npt) to add an outlet at the safety valve to bypass the regulator. At 150psi tank pressure, I get 100psi at the gun with the ten foot 3/8" hose. This is just above the 90psi gun rating. I believe that you don't necessarily need a big compressor for intermittent work, but I would recommend a 150psi or higher compressor if is a low cfm model. Keep the hose short. Fifty feet of 1/4" hose dropped the gun pressure to 40psi. The 1150 still loosened the axle nut, but more slowly.
The 1150 seems well made and is well balanced. An impact gun saves so much time spinning out even lower torque bolts such as for the caliper and control arms (50 ft/lbs and 100 ft/lbs). You'll be glad you bought one.
