Promotion Wholesale Ventilation Hot Air Blower/Industrial Centrifugal Blower Fan

Centrifugal fans use the kinetic energy of the impellers to increase the volume of the air stream, which in turn moves against the resistance caused by ducts, dampers and other components. Centrifugal fans displace air radially, changing the direction (typically by 90°) of the airflow.
Centrifugal fans with forward curved blades always require a spiral housing. Their characteristic features are a low noise level, relatively small air flow with a high increase in static pressure, and space-saving application.

Product Features:

Air-conditioning fan is a new kind of variable speed, enerousaving, high efficincy, and low noise Type centrifugal fan, thefan, compact structure, easy installation, small volume, windhigh pressure, large amount of small vibration, with three-phasevoltage regulator or inverter, can carry out Strict control speed.especially suitable for noise, big air volume range of ventilatedtake a breath Place, is air conditioning, purification, and otherdustries the ideal accessory products.

1.Structure: The new outer rotor fan's impeller is mounted directly on a rotating outer rotor's excircle ,impeller rotates together with the external rotor motor, motor's main shaft is stationary.
2.Stability: impeller and external rotor are fasten to the outer rotor's excircle by soldering or press fitting to form a whole. No secondary assembly errors, greater reliability and stability, less vibration.
3.Performance: more energy efficient, the national energy efficient products.
4.Noise: impellers after aerodynamic design again to ensure that the premise of wind capacity, lower noise, high efficiency, energy saving effect is more obvious.
5.Cooling: The motor is mounted in the middle of the fan impeller, better thermal performance, The motor itself has reached the maximum cooling effect and longer life.
