The piston cylinder type is used on large and slow speed stationary engines, but their use is
limited since they are bulkier, more expensive and less dependable than the rotary type blowers.
Centrifugal blowers are used both on low speed and high-speed engines. Centrifugal blowers
driven by exhaust gas turbine are small and light and are used for stationary, locomotive, and marine and
aircraft engine. The speed of the centrifugal type of blowers is high about 10000 to 15000 rev/min for
low speed engines and 15000 to 30000 rev/min for high-speed engines such as aircraft engines.
