Is it Right for Your Shop?

Whether or not this Northstar compressor is right for your shop mainly boils down to your air delivery needs. The 230V, 7.5 horsepower motor fills an 80-gallon tank to a maximum 175 PSI.

If that sounds like a win for you, durability is the next key. Northstar goes with a full cast iron pump that is the standard for heavy-use compressors that’s rated for 20,000 hours of use. There’s V-twin cylinder design that helps it cool more efficiently.

That’s great, but what does it translate to?

The Northstar 80-gallon compressor has a 100% duty rating – meaning it’s designed to be able to run all day.
