  • There are no clumsy belts to re-tension/replace!

These benefits translate into easier maintenance and reduced cost of ownership.

In addition, this features a unique pump design with a 2-piece cooling system that helps the unit cool more efficiently while extending the lifespan of the pump.

It’s also credited with the highest C.F.M output among direct-drive type compressors and has a running HP (horsepower) of 1.9.

The long-lasting induction motor means unbeatable performances all the time and reliability.

NorthStar Portable Gas-Powered Air Compressor 30-Gallon Horizontal Tank- Best air compressor 30 gallon for the money.

30 gallon air compressor lowes

This extremely heavy-duty air compressor also performs great and is also a lot quieter than other 30-gallon air compressors in the market.

It’s a true workhorse- it builds air pressure real quick (the approximated fill time is about 1 minute) and more importantly, keeps up with tons of air tools without issues.

In fact, it won’t run out of reserve air even when running heavy-duty accessories such as air impact wrench guns and like tools on general repair/maintenance jobs.

The 2 stage tool is quite easy to set up and the engine starts with just one pull every time.

And because of the fast recovery time, this works nearly continuously.

Plus, it features the Honda GX390 OHV engine, renowned for its amazing fuel economies.


  • PSI-175
  • Horsepower-12
  • CFM @ 175 PSI-18.7

We were absolutely blown away by the product and we are sure you’ll too.


2nd Runners up:

Ingersoll-Rand SS3F2-GM 30-Gallon Oiled Garage Mate -excellent for both professionals and enthusiastic do-it-yourselfers

Quietest 30 gallon air compressor

Engineered for situations where noise emissions should be kept low such as garages (hence the nickname Garage Mate), this is quiet enough for homes, shops, and various other job sites.

Belt-driven air compressors are quieter and this doesn’t disappoint (the dB is 75-80 when measured from a reasonable distance).

To be honest, this single stage unit is as quiet as they come for its size- it’s so quiet you easily forget its running.

It fills fairly fast as well, runs uninterrupted (it’s another outstanding 100% duty cycle air compressor), and operates more efficiently while remaining cooler than similar models.

The pre-installed semi-pneumatic tires make it easy to transport around job sites.

The portable air compressor is equipped with handy extras such as a safety valve and an auto start/stop pressure switch control.

In general, this is a great corded electric compressor to consider if you’re running pneumatic tools- nailing guns, ratchets,  grinders, drills, sanders, jack hammers, riveting guns, wrenches, etc.


  • Running Horsepower-2
  • Max PSI-135
  • NPT Outlet– 3/8 inch
  • SCFM @ 90 PSI– 5.7
  • Voltage- 115 V
  • Tool Weight– 185 Lbs
  • Decibel– 75 to 80 Db


  • Durable cast-iron construction
  • Protective enclosed belt guard
  • Manual over-load motor protection
  • 100% continuous duty
  • Also notable: A pressure switch, Regulator, 6-foot power cord, Pressure gauge , Manual drain


  • Good air capacity.
  • No annoying leaks.
  • Keeps pressure steady.


  • The ergonomic handle is a little difficult to install.
  • Doesn’t come with oil – you have to buy it separately.


This air compressor unit is, in our opinion, equal to similar brands (for the same specs) that cost way more.

It’s a first-class product that is reliable and friendly to use for professional or hobby applications.
