Technology comparison of magnetic suspension centrifugal blower with gear speed increase and air suspension blower:

Gear booster blower

-General Motors (50Hz) and gears increase the speed of the impeller.

-Use the inlet guid vane (IGV) or the diffuser vane to adjust the flow.

-Oil bearing (tilting pad) and cooling system were used.

Multistage centrifugal blower

-The compression efficiency is about 65-75%, which is generally used in the site with large flow.

With the exhaust pressure, the power also changes (compression stage).

-The compression efficiency is reduced because the multi-stage compression method is used for compression.

Magnetic bearing blower

-Turbine machinery design technology.

-High speed permanent magnet synchronous motor and impeller are coupled to drive.

-No loss, short after-sales maintenance period and low cost.

-Active control of magnetic bearing, high overall efficiency.

-ABS HST, Hoffman, Atlas Copco (zb-vsd), piller, Tianjin Yisheng, etc.

Air suspension blower

-The intelligent DC speed control system changes the shaft speed and the air volume.

-The flow pressure can be adjusted greatly and the rotation speed can be controlled.

-The air cleanliness is extremely high and it is not easy to maintain.
