Product Description

Ec Centrifugal Fans With Ventilating Units Pa66 Fresh Air System 225mm



If two motors are producing the same output but one has a greater power input then you can be sure that the surplus energy is being dissipated as heat. If an application is designed to remove heat then it will have to do extra work just to remove the heat produced by the fan motor itself, so EC fans will improve the efficiency of the whole system
