VAKUTEC® - Rohrradialventilatoren SRN3, SRM4, SRH4

Sizes and performance range:

The centrifugal tube fans in the above series are available in various sizes. The sizes are graded in standardised steps and enable the controlled extraction of atmospheres. The volume flow-pressure diagrams on the following pages are used for more precise dimensioning. The use of frequency controllers makes it possible to realise any speed, regardless of the nominal speed of the motors, so that the extraction performance can be adapted to the actual requirements. The maximum speed is limited by the material properties.

Drives and motors:

The impeller is driven directly by a motor built into the fan hub. This design means that the motor is completely separated from the aggressive exhaust air. The drive is an externally cooled three-phase squirrel cage motor with protection class IP55. On request, the fans can also be supplied with explosion-proof three-phase motors.
