Operation
Dust enters through the cabinet inlet and passes through
a fine mesh pre-filter on the outside of the filter. The
pre-filter is spaced 1-in from the filter cartridge and is
designed to catch fibrous dust while fine particulate
passes through to collect on the outside surfaces of the
filter cartridge. Clean, filtered air flows up through the
center of the filter cartridge to the blower, through the
silencer, and exits through the top clean-air outlet.
Model VS 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
60-seconds after the fan is turned OFF for the VS-550,
VS-1200, and VS-1500 and 180-seconds for Models
VS-2400 and VS-3000. This is the fan run-down time.
Power to controls must remain ON to operate cleaning
mechanism.
The vibration motor starts and filter cleaning begins for
a preset time of 30-, 60- or 90-seconds. A diaphragm at
the bottom of the filter cartridge opens when the fan is
turned OFF which allows fine dust particles to fall into the
dust drawer or optional hopper for disposal.
