Axial industrial fan FDA-2E-250S with grille Φ250 mm, supply voltage 220 VAC. Rated power 130 W and flow rate 1850 m3 / h. Suitable for refrigeration units and evaporators.
Axial fans are used when a big air flow is needed. Thanks to their low noise level they can be placed in ventilation shafts and air ducts in industrial halls and public buildings. When you choose a fan, it’s important that its characteristics correspond to the fan’s application.
The fan shouldn’t work in places where a vacuum may occur (for example if the fan suctions the air into a room without enough incoming air flow). Thus the air won’t be sufficient for the electric motor cooling and the fan will be damaged.
The fan speed can be adjusted with frequency inverter or phase controller. Please, have in mind that the speed decrease should be no more than ¼ from the nominal speed. If the speed drops off under 75%, the noise level decreases slightly but the fan motor cooling drops and that can lead to its damage. The fan can’t be powered by a DC/AC inverter with modified sine wave as this will damage it.
