FAQs about Air Compressors

How big of an air compressor do I need?

• The tank size needed for a job depends on the amount of air you need to store. A benefit to larger tanked air compressors is that the motor will not start and stop as often as a smaller tanked compressor. However, if you do not believe your project will require much air, it may be more cost-effective to use a smaller tank.

Can I use motor oil in an air compressor?

• Motor oil has a specific weight for designated uses. Only use the oil the manufacturer recommends for that distinct compressor. Each pneumatic air tool has its own individual CFM requirement that can be found in the owner’s manual.

What size air compressor do I need?

• To find out the size of air flow needed, you have to determine the PSI and CFM requirements of your air tools first. An easy way to select the correct air compressor size is by basing it on the highest-rated air tool you'll be using. Then, you'll never be under-powered and can maintain efficiency.
