Spout Dust Collector
OPERATION LOGIC: Input power is applied to the timer control circuit board, which is in parallel with the low voltage (120/60/1) coil of the fan magnetic starter. Upon fan start power is supplied to the control board, and “preset” off time is initiated. At the end of the “off” time, the control energizes a solenoid that provides the cleaning pulse for the filter tubes, and then steps to the next segment. This cycle is continuous unless an auxiliary control, such as a pressure switch, is used to control the timer.
