It's very important to know if the air compressor you plan to purchase will properly drive the air tool you're going to use for your project. For example, smaller air nailers run on 2 to 5 CFM (Cubic Feet per Minute — units in which air flow is measured) at 70 to 90 PSI (Pounds per Square Inch) mostly due to intermittent quick bursts of air for shooting nails, while larger grinders, sanders and polishers require up to 10 or more CFM and 100 to 120 PSI because of the constant air load for continuously spinning the wheel/abrasive/pad. Below you'll find the types of air compressors, features, and how to find the right air compressor for your needs.
Compressed air power tools, also known as "pneumatic” power tools, can dramatically decrease the amount of time spent on a project. Many homeowners and DIYers prefer smaller, more portable units (either hand-carried or wheeled) that move easily from the garage to the house, yard or roof. Common household applications include inflating sporting goods and toys, tires and running air tools that don’t have large air requirements like nailers and staplers.
Air compressors used for business, professional or commercial applications are often classified “industrial grade” compressors. They're packed with features and higher specs that let you take on more heavy duty jobs with more horsepower, more CFM, more PSI and longer run times. Though some commercial compressors are portable, many are stationary units with a large tank capacity, ASME certified air tanks (up to 120 gallons), higher HP, more CFM (air volume) and faster recovery times to run a huge array of air tools for as long as you need.
Finding Out Your CFM Requirements
The chart below shows some common air tools and their average CFM air volume measurements. Use this chart to determine what continuous CFM rating is required of your air compressor. Air tools are often rated as “Average CFM.” “Average CFM” is usually based on a 25% duty cycle (15 seconds out of a minute.). Tools that require continuous power output (ex. orbital sanders, angle grinders, etc) may run into the problem of requiring a greater CFM to run continuously. Nailers, staplers and impact wrenches typically do not have the same problem since by their nature are used more intermittently.
*Note - If you plan on using an air tool on a continuous basis, it is a good idea to multiply the “Average CFM” x 4 to get a continuous CFM rating for the tool.

Two-Stage Compressors versus Single-Stage Compressors
Single-Stage compressors have one piston that compresses and pushes air to the storage tank. The single-stage system is normally found on light-duty compressors with a maximum rating below 150 pounds of pressure per square inch (PSI). Single-stage compressors are adequate for most home users and small DYI projects.
Two-Stage compressors have two pistons that compress and deliver air to the storage tank. The first piston compresses the air and pushes it through a check valve to the second piston. The second piston further compresses the air and delivers it to the storage tank. A two-stage system is usually found on commercial heavy-duty compressors with maximum ratings above 150 PSI. Two-stage compressors are good choices for continuous use or shop environments.
Things to Consider
Horsepower Ratings are a measurement of the horsepower (HP) the compressor motor produces. Compressor motors generally range from 1.5 HP to 6.5 HP. More powerful units are available for industrial applications. Higher horsepower motors generally have greater psi and are capable of carrying a heavier workload.
Compressor Storage Tank Size is rated in gallons. Larger tanks store more compressed air at higher pressures. The amount of air a compressor delivers is measured in CFM (cubic feet per minute). Do note that the CFM a compressor delivers changes at varying psi. Most air tools have very specific running requirements for volume and pressure. These requirements must be met for the tool to function properly and effectivly. When choosing a compressor, consider the tools you want it to operate. Select the tool that requires the highest CFM at the highest psi, and add 50% to the required CFM for a margin of safety. For example, if a tool requires 3 CFM at 90 psi, select a compressor that delivers at least 4.5 CFM at 90 psi. Use this formula to be sure that the tool receives enough air to function the way it was intended.
Oil-Free Compressors have sealed bearings and require less maintenance than oil-lubricated compressors. Oil-free compressors have plenty of power for most non-commercial/home uses.
Oil-Lubricated Compressors require the user to change the oil regularly. (Consult the owner's manual for specific intervals and oil type). Most industrial/commercial compressors are oil-lubricated.
Electric-Powered Compressors are the most common and are easy to use in any area with a ready electrical supply.
Gas-Powered Air Compressors are a good choice for areas where electricity is limited or unavailable. Don't use gas-powered compressors in confined or unventilated areas.
