Abstract
PURPOSE: Ventilating system such as dust collector is provided with an electric damper and a controller for the revolving number of blower motor which sends air in the ventilating system, thereby effecting free air control according to load.
CONSTITUTION: The degree of opening of the electric damper 17a is controlled through the pressure controller 18 and the pressure detector 16 which detects the pressure of the point 12a in the dust collector 12. The degree of opening of the electric damper 17b in the bypass duct 19 is controlled through the flow controller 21 and the flow rate detector 20 in the exhaust duct 13. The revolving number of the driving motor 14 for the blower 10 is controlled to the desired value by the speed controller 22 to thereby effect desirable control of air flow rate.
