Able to generate a substantial volume of air with minimal vibration in a limited space, centrifugal blowers are used in a wide range of air conditioning, ventilation, heating and clean room applications. A centrifugal blower intakes air through its center and directs it through a perpendicular opening in the housing. Unlike many other blowers, this is accomplished through an impeller, which is a vaned disk that increases pressure and flow of the gas being moved.

Centrifugal blowers find use in certain automotive applications; a centrifugal supercharger or turbocharger is basically a modified centrifugal blower. The boost generated from the supercharger is based on the speed of the blower, although care should be taken not to exceed the capacity of the engine, as this can lead to engine damage. Generally, when a turbo is not used, other blower types are preferred.

Both single and multi-stage centrifugal blowers are produced by manufacturers. Single stage blowers are effective in applications that call for uniform air flow across a full volume, including ventilation and conveying operations. Multi-stage blowers are useful in situations that require variable flow at a steady pressure, such as convection drying, water treatment and chemical gas compression. Often, single stage compressors use aluminum impellers, while multi-stage devices employ impellers made from steel, cast iron or aluminum.

When installing a blower system, take care to include appropriate space for effective maintenance as well as the proper filtration. Manufacturers will provide specifications on the flow rate and pressure capacity, and the cutoff S.P., as well as the horsepower of the unit. Centrifugal blower repair services are also available through select businesses; typically blower repair includes the replacement of seals, rings and other hardware, plus complete performance calibration.
