Intended Use
The NorthStar 30-Gallon Electric Air Compressor provides compressed air for air tools and pressurized
objects that require high air pressure. It features:
•Maximum Efficiency: Heavy-duty induction motor for maximum performance and efficiency.
•Long Lasting Operation: Cast iron oil-lubricated pump for long service life.
•Versatile Operation: Dual voltage motor is wired for standard 120V outlets but can be converted to
240V applications.
Note: Do not use for low-pressure objects such as balloons, air mattresses, and sport balls, which can
explode quickly and easily. Special precautions are necessary when used for cleaning to prevent flying
debris hazards. It is not to be used to supply breathing air.
