Axial industrial fan BDRAX-250-4K with grille, supply voltage 230 VAC with power 60 W, working opening 250 mm and flow 870 m3/h. It is possible to reduce the fan flow rate with a properly selected frequency controller.
Axial fans are the most common type of fans and are widely used in both the household and the industry. Among their advantages are high flow, low noise and reliability. For installation in industrial, public buildings and laboratory ventilation systems
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 50%. The fan can not be powered by a DC / AC inverter with a modified sinewave - this will cause it to malfunction.
