Cast Iron Industrial Centrifugal Air Blowers

A centrifugal blower is an air moving device that uses an impeller to pull air into a tube like structure and release it at a 90o angle. The impeller is a set of blades inside the blower that rotates at a high rate to pressurize and move air.The property that distinguishes a centrifugal fan from a blower is the pressure ratio it can achieve. In general, a blower can produce a higher pressure ratio.
