Superior Design for Industry-Leading Pumps

Low Vibration and Durability

The last thing you want to worry about is your compressor breaking down in the middle of a job. The NorthStar® 3-Cylinder Air Compressor Pump has been engineered with superior technology to keep you working without interruption. Innovative Low Vibration Technology (LVT) gives you a dynamically balanced pump for smooth operation and long service life. Bearings are placed on both ends of the pump’s crankshaft for superior support and less wear and tear. The result is reliable, dependable operation of your NorthStar® air compressor pump, year after year.

Longer Pump Life

Heat can be a powerful enemy to the longevity of your air compressor pump. That’s why this NorthStar® 3-Cylinder Air Compressor Pump has been engineered with a W-style cylinder orientation to eliminate hotspots and provide consistent cooling, resulting in longer pump life. The pump cylinders, heads and crankcase are made of cast iron for extra-long service life. And the pump utilizes premium-quality floating-type Swedish steel valves for trouble-free performance. Thanks to this excellent technology, you can count on your NorthStar® air compressor pump to perform flawlessly for many years.
