Centrifugal blowers with various types of radial impellers are commonly built as AIR HANDLER and MATERIAL HANDLER.

1. Air-handling fans are designed to move air or gas at high pressure. Application of these fans are in the areas of pollution control and other special equipment.
2. Material handling fans are designed for use in air containing fibers, stringy and granular materials, as well as dust.
3. High pressure blowers are used in the applications requiring low or moderate air volume at pressure ranging up to 150 inches of water column. Typical applications include industrial combustion, pneumatic conveying, blast furnaces, air scrubbers, and many other special applications.
