Plug Fan

Plug fans are the centrifugal blower / industrial blower which generally don't have the housing, it is also known as open type fan. It is majorly used for hot air circulation, autoclave vessels or in the dust collector where they are fitted directly on the body.Electrically commutated (EC) plug fans use a brushless EC motor in a backward curved motorized impeller (plug fan). An EC motor is actually a DC motor that can be connected to an AC supply line, due to a rectifier internal to the motor drive. Speed control is achieved by varying the control voltage from zero to 10 VDC.
