Multi-stage centrifugal blower is widely used in sewage aeration treatment, flue gas desulfurization, denitration, vacuum drying, powder and granular body transportation, coal preparation and coal washing, nitrogen boosting, biogas boosting, negative pressure dust removal, high temperature circulation and other fields

Operating Principle

Blowers are dynamic radial compressors. They build up a pressure by accelerating the fluid  in a set of impellers and then decelerating

the fluid by means of long-radius and high- efficiency diffusers.

By activating a valve located on the suction side, RH blowers’ special design allows for modulation of airflow while maintaining a constant pressure. The power consumption is thus in direct proportion to the required mass flow rate.

Applications

Designed to handle air or gas, RH blowers are used in the following applications:

• water treatment

• waste water treatment

• biogas recovering

• combustion air

• central vacuum cleaning

• fluidization and homogenization of silos

• liquids or baths aeration and agitation

• air knife drying

• galvanizing process
