Combustion Blower

Major types are centrifugal blower and positive-displacement blower.Centrifugal blowers look more like centrifugal pumps than fans. The impeller is typically gear-driven and rotates as fast as 2900 rpm. In multi-stage blowers, air is accelerated as it passes through each impeller.In single-stage blower, air does not take many turns, and hence it is more efficient. Centrifugal blowers can achieve higher pressures up to 1500 mmWC
