Weighing in at a little over 200-pounds, the vertical NorthStar 25653 model air compressor is quite heavy. The unit includes two wheels located at the base to allow for easy portability.


The 2-horsepower dual voltage induction motor with a single-stage pump delivers 6.0 CFM at 40 PSI and 5.0 CFM at 90 PSI. It is powerful enough to use for many projects and use with many air tool accessories. It includes a 6-foot cord and plug and wired for 115-volt operation. The unit provides a lifetime of 20,000 hours of use and includes reed valves that are made of heat-resistant alloy steel, heavy-duty paper element filters, and is ASME certified. The double ringed-style piston consumes very little oil and helps to extend the lifetime of the piston head. In addition, the motor is designed to easily start in hot and cold weather.
