Backward curved centrifugal fans-Products-Schnirofan

Axial fans

Backward curved centrifugal fans

Forward curved centrifugal fans

Project fans

EC motor driven fans

High air volume and efficiency

The centrifugal fan with backward blades is designed as a free-rotating fan without the need for a volute,
For centrifugal fans with Schniro outer rotor motors,
The motor is located in the impeller,
In addition to optimizing motor cooling, a particularly compact design has also been achieved.
