Air Compressor Basics
An air compressor is a powerful tool that converts power into potential energy stored in pressurized air. Understanding its basics helps you use it safely and effectively. This section explains how air compressors work, the types available, and their common uses.
How Air Compressors Work
An air compressor pulls in air and squeezes it into a smaller space. This process increases the air pressure inside a tank. The compressed air stays stored until needed. When turned on, the compressor pushes air out with force. This air can power tools or inflate tires.
Types Of Air Compressors
There are two main types: piston and rotary screw compressors. Piston compressors use a piston inside a cylinder to compress air. They are common for home and small workshop use. Rotary screw compressors use two screws that turn to compress air. They are often used in large industrial settings. Some compressors are portable, while others are fixed in place.
Common Uses
Air compressors serve many purposes. They inflate tires, sports equipment, and air mattresses. They power nail guns, spray painters, and impact wrenches. In workshops, they clean surfaces and operate machinery. Compressed air also helps in construction, automotive repair, and home DIY projects.

- Test the tool briefly to confirm the pressure feels correct.
Pressure For Specific Tools
- Nail guns usually need 70 to 120 PSI for proper firing.
- Impact wrenches work well between 90 and 120 PSI.
- Paint sprayers require lower pressure, around 30 to 50 PSI.
- Blow guns use low pressure, often below 30 PSI.
- Check each tool’s manual for exact pressure recommendations.
Recommended Psi For Tires
- Passenger car tires usually require 30 to 35 PSI.
- Light trucks may need 35 to 45 PSI.
- Check the tire sidewall or vehicle manual for exact PSI.
- Use the air compressor’s gauge to avoid overinflating.
- Stop inflating once the recommended pressure is reached.
Connecting Tools And Accessories
Connecting tools and accessories to an air compressor is a key step for smooth operation. Proper connections ensure air flows efficiently and safely. This section explains how to attach tools and accessories correctly.
