2. NorthStar Portable Gas-Powered Air Compressor

Some people swear with electric air compressors because they’re affordable and suitable for light and heavy-duty projects. But as good as electric models are, you can’t bring them just about anywhere and expect them to get the job done.

In fact, when you have projects that you want done from any location, a gas-powered model is the best solution. 

NorthStar Portable Air Compressor is one such great example. It’s a gas-powered model that you can take anywhere with you to get the most demanding jobs completed within a short time. 

It’s made of 100% cast iron for strength, durability, and proper heat dissipation. It delivers guarantees a maximum 4.8 HP, which is quite impressive for a gas-powered machine. With such a powerful motor, you can expect the machine to produce 13.7 CFM at 90 PSI.

The 163cc Honda engine that powers this air compressor includes a lower vibration technology, which is why it has the potential to deliver a higher CFM unlike electric models of the same size.

Gas-powered air compressors are often expensive, and this model isn’t an exception. But the biggest advantage of such a model over electric or battery-operated ones is that you do get incredibly high power output that’s also more consistent.

Going for under $600, the NorthStar Drive is a good deal for those who are interested in an air compressor that doesn’t take too much space in a garage, commercial facility, or workshop.

NorthStar Drive is one of the models with American Society of Mechanical Engineers certification. It includes components such as heat-resistant regulator valves, integrated regulators, performance optimized air filters, and dual crankshaft.

From a design standpoint, we think NorthStar has done a great job to make this as sturdy and strong as possible. The cylinder is made of cast iron for strength and durability.

The material also ensures there’s proper transfer of heat, thus keeping the pump in the best condition possible.

Thanks to the belt driving mechanism and the oil lubed pump, this machine never make loud noise when it’s in use. Your neighbor on the other side of the door won’t hear it, making it one of the best options to consider if noise is an issue where you come from.
