Permanent magnet variable frequency multistage centrifugal blower

Product range：

Flow to 15 000 m³/h

Press to 1.5 barg

The international standard multi-stage centrifugal blower using modern design and manufacturing process because the impeller is cast in aluminum alloy, not only the rotor is light, but also high efficiency, the bearing can use simple ball bearings, full air-cooled design, has an incomparable advantage over the traditional welded impeller manufactured multi-stage centrifugal blower. Especially in the flow of more than 15000m³/h models, the efficiency of this multi-stage centrifugal blower in many conditions, the efficiency of the whole machine is not lower than the suspension blower and the traditional integral gear growth blower. However, on small flow models, the efficiency of this fan is lower than that of the suspension fan now developed.

Multistage centrifugal blower is an efficient blower integrating modern fluid machinery and motor technology, aluminum alloy casting high efficiency closed three-way flow impeller, specially designed step seal between the teeth and high efficiency permanent magnet variable frequency motor and control technology, the efficiency of the whole machine in many common conditions is higher than the standardized suspension fan. Due to the use of ordinary ball bearings, the reliability and maintainability are also much higher than the suspension fan.

Product characteristics：

Three dimensional flow closed impeller, efficiency up to 93%.

The efficiency of permanent magnet variable frequency motor is as high as 97%, which has excellent characteristics unmatched by general motors.

High performance frequency converter is used to control the speed, and a variety of control modes can be selected.

Direct drive without speed box, no oil lubrication, no water cooling (water-cooled bearing seat can be optional for large flow models).

Using ordinary deep groove ball bearing, reliable operation, easy maintenance.

The fully enclosed air cooling system is used to dissipate heat from the motor to ensure that the fan is in a stable and efficient running state.

Modular design, easy and fast maintenance.

Intelligent control system monitors the running status of the fan in real time, adjusts the flow pressure on demand in time, and integrates anti-surge system to ensure safe and stable operation.
