Consumer-grade air compressors can be described as a pancake or single-stage model. They’re used for household tasks like inflating tires and inflatable products and low-load air tools like staplers and brad guns.

Professional-grade air compressors provide more power and higher pressurized air. They could be two-stage reciprocating models or rotary screw models and can provide more power to run several air tools at once with intermittent use.

A standard air compressor works on the same principle as a water pump. It has one or more piston cylinders, which draw air in from the atmosphere on the upstroke and push it out to the gun on the downstroke. This generates a constant supply of compressed air, which flows through a hose into the gun's air reservoir.

Compressor safety:


Electrical dangers: If an outlet isn’t grounded correctly, it can result in electrical shocks for your operators or irreparable damage for the machine. Also, be sure to follow the instructions in the owner’s manual for extension cord use.

 

Flying particles and debris: Highly pressurized air and pneumatic tools can cause flying debris. If it strikes an operator, the pieces can cause bodily injury, or they can become lodged in the machine, causing damage.

 

High pressures: If high-pressure air is injected into the body, dangerous conditions and injuries, such as air embolism, ruptured eardrums and ruptured organs, can result.

Noise: The noise from the compressor machine can also cause hearing loss so be sure to use hearing protection. 

Drain the air from the compressor when finished.
