A centrifugal
fan has a central hub with several blades at a right angle. Sometimes
called a blower, a scroll-shaped structure houses the fan assembly. It
increases the incoming pressure of the air or gas and forces it in
another direction. The flow rates of centrifugal fans are lower than
axial fans, but the pressures are higher. We can alter the design to
change the performance of the centrifugal fan, creating different
pressures and airflow.
Centrifugal
blowers with various types of radial impellers are commonly
built as AIR HANDLER and
MATERIAL HANDLER.
- 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.
- Material handling fans are designed for
use in air containing fibers, stringy and granular materials, as well
as dust.
- 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.
