PZ Series 150-250-500-1000 Shaker Cleaner
Operation
During normal operation, dust-laden air enters the
collector through the dirty-air inlet. The velocity is
reduced and natural pre-separation, caused by the
effects of gravity, takes place and heavier particulate
falls directly into the collection bin or hopper. Fine
particles collect on the outside surface of the filter bag
and filtered air passes to the center of the bag and
discharges through the clean-air outlet.
The Unimaster is an intermittent-duty collector, which
means that cleaning starts when the fan is turned OFF
and the appropriate fan run-down time is complete.
The solid-state timer automatically starts the cleaning
sequence 75-seconds after the fan is turned OFF. This is
the fan run-down time. Power to controls must remain
ON to operate the cleaning mechanism. The vibration
motor starts and filter cleaning begins for a preset time
of 30-seconds.
