Comparing pumps, compressors, blowers and fans
Significant differences between pumps, compressors, blowers and fans are summarized below
Pumps
- A
pump is a machine for raising a liquid - a relatively
incompressible fluid - to a higher level of pressure or head.
Compressors
- A
compressor is a machine for raising a gas - a
compressible fluid - to a higher level of pressure.
Blowers
- A blower is a machine for moving volumes of a gas with moderate increase of pressure.
Fans
- A fan moves large amounts of gas with low increase in pressure.
