Title: The Three Types of Air Compressors


1
The Three Types of Air Compressors
  • COMPRESSOR WORLD

2
Measuring Air Pressure
  • 1. Air pressure is usually measured in psi
    (pounds per square inch).
  • 2. Air pressure measured above atmospheric
    pressure is measured in gage pressure (psig),
    while pressure measured against vacuum is
    measured in (psia).

3
Three Main Types of Air Compressors
  • Reciprocating Compressors
  • Rotary Screw Compressors
  • Centrifugal Compressors

4
Pros and Cons of Reciprocating Compressors
  • CONS
  • Maintenance is problematic.
  • Creates a lot of noise.
  • Cant be used for bigger applications.
  • Replacement of oil-free parts can be expensive.
  • PROS
  • Better for homes where smaller applications are
    required.
  • Uses very little power.
  • Is extremely affordable.
  • Is operable under a wide range of pressure.

5
Pros and Cons of Rotary Screw Compressors
  • CONS
  • Is good only for medium loads.
  • At the time it is unloaded it can use 50to90 of
    the power.
  • PROS
  • Continuous Intercooling and excellent efficiency.
  • Extremely low cost of maintenance.
  • No noise.
  • Can be operated for a long period of time.

6
Pros and Cons of Centrifugal Compressor
  • PROS
  • Is the best for heavy pressure applications.
  • Requires very less maintenance.
  • Is beneficial in applications when the load is
    greater than 200 hp.
  • CONS
  • Cannot give as much efficiency as a rotary screw
    compressor.
  • Intercooling should be provided in case being
    used for applications that need higher pressure.
