Multistage centrifugal blowers (AIR/GAS)

Operating principle: One stage of a MAPRO® multistage centrifugal blower is generally made of:

• an intake duct conveying the gas to the impeller inlet,

which is coaxial to the shaft;

• a closed impeller with axial flow inlet and radial flow exit;a radial diffuser, whose aim is to convert kinetic energy
• into static pressure at the impeller exit;Note: The system can be customized according to client requirements, and competitive pricing is offered.

  a discharge volute. Actually, a centrifugal blower is always used in the multistage configuration. The gas is sucked into the first stage through an inlet volute, every next single stage is linked to the former one through a return channel, and a discharge volute collects the gas from the exit of the last stage delivering it to the outlet pipe. The impellers are built with radial exit blades or backward facing blades. The radial blades allow the achievement of a higher compression ratio, whilst the impellers with backward facing blades, at fixed speed of rotation and for the same differential pressure, produce a characteristic curve with a much wider stable range.
