Radial fans

  • The radial fans are adjustable in the complete voltage range.
  • The winding is carried out on IP 44, on request also in IP 54 as well as with isolation for tropical climate.
The input area covers all conceivable inputs for the promotion of dust-free air and little aggressive, non-reactive gasses or vapours.
  • The exact temperature range is gathered from the ending eloquent data sheet in the axial list, however, can be set flatly approximately at a maximum duration temperature of 50 to 80 degrees Celsius.

The asynchronous motors of Kaiser Ventilatorenbau are especially developed motors for fans. The motors are completely closed into themselves. The external surface of the motors is provided with cooling fins. Because the motor is in the stream of air of the fan, a good heat transfer is given just at speed control. Further special mechanical design measures ensure a 100 per cent speed control without the motor being able to overheat themselves.

 

 

For different input purposes also different fans are needed so that different forms are offered:
