The gas transported by the fan should be non-corrosive, non-flammable, non-explosive and non-sticky.
Operating conditions: the ambient temperature range should be:-40℃---+60℃, the relative humidity should be less than 90%, the altitude should be less than 1000 meters.
Put simply, DC motors are around 30% more efficient than AC motors because the secondary magnetic field comes from permanent magnets rather than copper windings.
An AC motor consumes additional energy solely to create a magnetic field by inducing a current in the rotor. But this is only half the story. The use of modern electronics in controlling the motor has opened up many other possibilities which contribute to using less power
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.
Can be pre-configured to suit specific sensors and applications, and are supplied standard with 0-10V control input.
A full range of sensors are available including differential pressure, humidity, temperature, air velocity and pollutant.
