VARIABLE EXHAUST CONTROL FOR SPRAY BOOTHS

摘要

An exhaust control system for a spray booth having at least one fan motor. The exhaust control system comprises a spraying activity detector and a speed control circuit for an electrical motor. The speed control circuit is connected to the fan motor and is linked to the detector so as to adjust the speed of the motor in a variable manner as a function of at least the spraying activity. A method for controlling an exhaust system of a spray booth having at least one fan motor comprising the steps of detecting a spraying activity and, upon detection of the spraying activity, increasing an air volume exhaust rate of the exhaust system.
