and are pulsed automatically by the dust collector timer controller during operation. For more
information on diaphragm valves, refer to the manufacturer data in the associated cut sheet. For
maintenance, see
Section 6.14.1
MULTI PLEATED DUST COLLECTION FILTER PACK
The dust collection filters are mounted between the tub and the plenum and can be reached via the
access panels on the plenum. Filters remove product from the airstream before it enters the plenum,
allowing air to be routed directly out of the plenum into the atmosphere without further need for
processing. Each filter can accommodate a volume flow rate of 500 CFM. Manufacturer data can be
found in the associated cut sheet; for filter inspection and replacement, see
Section 6.13
ENCLOSURE CONTAINING THE DUST COLLECTOR TIMER CONTROLLER
The dust collector timer controller is located inside an enclosure on the side of the unit. The timer
controller regulates the purge sequence by signaling the pilot valve connected to each diaphragm
valve, controlling both the time between each purge and the duration of each purge. The controller
also monitors the pressure differential across the filters for maintenance purposes. Manufacturer
data can be found in the associated cut sheet.
SOLENOID DRAIN VALVE
The drain valve is connected to each header and serves to remove condensation accumulated in the
headers. After each purge cycle, the dust collector timer controller opens the drain valve, which
evacuates the water from the system. Manufacturer data can be found in the associated cut sheet.
For maintenance, see
Section 6.14.3
EXHAUST FAN
The exhaust fan is mounted to the top of the plenum and serves to drive air from the spout and the
container being loaded through the filters and out into the atmosphere. In some cases, air may be
ducted from the outlet of the exhaust fan; however, this is usually not necessary. Do not duct the
outlet air unless the system was originally designed with this specification in mind, as ducting the
outlet air induces a higher load on the exhaust fan. The volume flow rate is controlled by means of a
damper on the outlet of the fan. Use care when adjusting the volume flow rate to ensure that the
maximum flow rate for the filters and the maximum load on the exhaust fan motor is not exceeded.
See the manufacturer’s component data in the associated cut sheet for more information; for
exhaust fan burn-in instructions, see
Section 4.3.4
