Centrifugal type "snail" industrial fan BDRS 120-60, supply voltage 230 VAC with power 85 W, working opening 80x70 mm and flow 275 m3/h. It is possible to reduce the fan flow rate with a properly selected frequency regulator.
The fan is not allowed to operate under vacuum conditions (for example, the blower can take air out of a room that can not get enough air otherwise). This will result in insufficient airflow to cool the motor and the fan will be damaged.
It is possible to adjust the fan speed by means of a frequency inverter or by phase adjustment with a reduction of the speed up to 75%. The fan can not be powered by a DC / AC inverter with a modified sinewave - this will cause it to malfunction.
