Centrifugal duct industrial fan VR-2E-100, supply voltage 230 VAC with power 60 W, working opening 100 mm and flow 350 m3/h. It is possible to reduce the fan flow rate with a properly selected frequency controller.
For air suction in indoor premises. This centrfugal pipe fan is intended to be built in walls, ceilings, air shafts, etc. in order to provide a good ventilation with direct air suction outside or through an air duct.
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.
