How It Works
During normal operation:
- During normal operation, the dust laden air from the plant travels down the extract duct.
- A standard baffle is mounted at the inlet of the filter to break up the air flow and direct the dust downward into the hopper section while protecting the filter media from abrasive dusts.
- The lighter dust collects on the inside of the filter bag as clean air passes through. Finally, the clean air travels up through the air handling fan where it could be returned to the plant or exhausted outdoors.
- The heavier dust settles in the hopper section where it is discharged into a metal bin.
While Cleaning:
- Each time the filter unit is turned off, there is a 2 minute delay and then the automatic timer activates the shaking motor.
NOTE: The cleaning cycle is set to 8 seconds. - The shaft of the shaker motor is attached to a simple cam which, in turn is attached to the shaking mechanism. The shaking mechanism pivots vigorously which causes the dust to break free from the inside of the filter bag.
- The dust then falls into the quick-release metal collection bin located at the bottom of the filter unit.
