Things to Consider When Picking an Air Compressor

• 

  Size

  A compressor that’s too small will need time to recharge its pressure after a few uses, which can be frustrating to wait for. One that is too big will use an unnecessary amount of energy, increasing operating costs.

• 

  Airflow

  A compressor’s airflow is measured in cubic feet per minute (CFM) and should be greater than its operational requirement but less than its maximum output. Calculate the CFM of all tools you’ll be using on a regular basis, then add a buffer of 30 percent to ensure you won’t run out of air pressure and have to wait.

• 

  Electric vs Gas

  There are two ways to power a compressor: electricity or gasoline. Electric motors are lower maintenance and less expensive, while gas motors offer portability and manoeuvrability.

• 

  Additional Features

  Look for the little extras that can make life and maintenance easier, like stainless steel finger valves to eliminate corrosion, oil-monitoring devices to prevent damage caused by low oil levels, one-piece connecting rods for fewer internal adjustments, and more.

• 

  Tools

  Using an air compressor for pneumatic tools means you can get the job done faster, more efficiently, and more powerfully. Some tools that use an air compressor include: nail guns, orbital sanders, reciprocating saws, socket and ratchet wrenches, drills and drivers, air hammers, paint sprayers, tire inflators, and more.
