On the one hand, oil-lubricated pumps like you’ll find on the Makita Big Bore Sir Compressor keep the air compressor going longer and avoid overheating by keeping operating temperatures low.

Portable air compressors can go through some tough challenges, especially if you’ll be tossing them in the back of your truck to take to job sites.Unlike the California Air Tools Steel Tank Air Compressor, the Makita Big Bore Sir Compressor is small enough to remain out of the way when not in use. The Makita Big Bore Sir Compressor is 81 pounds with no wheels, although you could put it on a cart with wheels. Its massive 18.7-inch X 16.2-inch X 29.6-inch size would hardly make it inconspicuous when you aren’t using it, though. Although it’s a whopping 90 pounds, the California Air Tools Steel Tank Air Compressor has wheels, so you can easily move it around if you plan to keep it in the same area. The PORTER-CABLE Pancake Compressor comes close, at only 34 pounds. The DEWALT Pancake Compressor is the lightest, at only 30 pounds. If you’re shopping for a portable air compressor, chances are you want it to be portable.That not only means lower electric bills, but also less worrying about tripping a breaker during your next project. Although it’s powerful, the 2.5 HP motor in the Makita Big Bore Sir Compressor is built specifically to minimize draw on your power supply.

All that power can push your utility bills up a little, though, so consider power usage when you’re shopping.For instance, if a tool says it needs 5.0 CFM at 90 PSI, you’re going to need an air compressor that outputs 6.25 to 7.5 CFM at 90 PSI. You’ll need more air output than the tool states. It’s important to pay attention to this number because some power tools have a minimum PSI per CFM. Compare this to the PORTER-CABLE Pancake Compressor, which outputs 90 PSI at 2.6 CFM. The California Air Tools Steel Tank Air Compressor handles up to 5.60 cubic feet per minute at 40 PSI and 4.40 CFM at 90 PSI. It’s also important to consider output, not only for effectiveness but also recovery time.The Makita Big Bore Sir Compressor maintains an operating pressure of 130 PSI, and the California Air Tools Steel Tank Air Compressor also impresses, maxing out at 125 PSI. The DEWALT Pancake Compressor and PORTER-CABLE Pancake Compressor are the leaders in this area, sustaining an operating pressure of up to 165 PSI and 150 PSI, respectively.


Chances are, you’ll want it out of the way when it’s not in use, but some can be massive, especially for an air compressor billing itself as “portable.” Take a look at where you’ll store your air compressor, and pay close attention to dimensions to make sure you don’t end up with a space hog. You should also consider size when choosing an air compressor. If you opt for a larger air compressor without wheels, consider purchasing a cart with wheels or casters if you need to even occasionally move it around. Some air compressors come with wheels, but that won’t help while taking it up and down stairs. In a portable air compressor, it’s important to take weight and size into consideration. You can also use a portable air compressor to quickly clear debris from a work area, boosting its versatility. But perhaps the biggest reason to buy an air compressor is to power tools like nail guns, air impact wrenches and air hammers. You can use an air compressor for everything from spray painting a wall to doing minor car repair work. Even if you only ever use it to make sure your vehicle tires stay properly inflated, it’s handy to have around. An air compressor is a must-have tool for any DIYer.
