Axial industrial fan FDA-4E-400STM with grille, supply voltage 230 VAC with power 180 W, working opening 400 mm and flow 4800 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.
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 thermal protection will work, preventing damage to the fan.
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.
