compressed - air system

1. what is an air compressor?
2. define quick disconnect couplings.
3. what is the usual air pressure in a shop’s compressed - air system?
4. a(n) ____ is used to set a specific pressure in the compressed - air system.
5. identify the components of the compressed - air system illustrated below.

Explanation:

1. An air - compressor is a device that increases the pressure of air by reducing its volume.
2. Quick - disconnect couplings are fittings that allow for easy and rapid connection and disconnection of hoses in a compressed - air system without tools.
3. The usual air pressure in a shop's compressed - air system is around 90 - 120 pounds per square inch (psi).
4. A pressure regulator is used to set a specific pressure in the compressed - air system.
5. (A) Air tool; (B) Quick - disconnect coupling; (C) Hose; (D) Filter; (E) Regulator; (F) Lubricator; (G) Pressure gauge; (H) Compressor motor; (I) Air tank.
