6. Operation
Before operating the central safety filters, make sure all mechanical installations are
complete.
Make sure all electrical and compressed air connections are complete and correct.
Make sure that no leaks are present in the filter chamber housing. Check clamps for
proper adjustment.
6.1. Adjusting the Blowback Air Pulse Timing
The length of the air pulses and the time between air pulses require adjusting to match up with
dusting characteristics of the material being conveyed. If more dusting occurs, then quicker and
more frequent compressed air pulses are required to clean the filter element.
Central Conveying Control. To adjust the blowback air pulse timing, refer to the manual for the
central conveying controller.
Compressed Air Blowback with Integrated Control. Locate the timer inside the control
enclosure on the circuit board. With the unit operating, turn the potentiometer counterclockwise
to speed up the timing (shortening the air pulse duration and time between air pulses); turn
clockwise to slow down the timing (lengthening the air pulse duration and time between air
pulses).
