AW16000 - Instruction Manual
Dust Collectors are dry, reverse pulse jet cartridge collectors, used to ventilate abrasive blast cabinets and remove
dust from exhausting air.
The exhauster is mounted on the clean-air side of the filter cartridges, and provides «pull-through» (pulls air
through the reclaimer) air flow rated at 600 to 1800 cfm depending on the exhauster size. Dust and particles are
drawn through the reclaimer into the dust collector, trapping dust before discharging clean air.
Filter cartridges are cleaned by a pulse of high velocity compressed air expanding against the inner surface of
the cartridges. The expanding air momentarily reverses air flow through the cartridge, releasing dust that has
accumulated on the outer surface. The dust particles fall away from the cartridges and into the dust drawer.
The pulse interval are controlled by a sequencer located in front of the dust in the plastic electrical box. The timer
controls the «on» time (the length of time for each pulse) and «off» time (the length of time between each pulse).
The «on» time should never be adjusted. The lower the setting for the «off» time, the shorter the length of time
between pulses.
CAUTIOn : do not pulse new dust collectors or replacement cartridges until the cartridges are
properly seasoned. See page 13 pulsing unseasoned cartridges could cause premature cartridge
failure or decrease the efficiency of dust collector.
The differential pressure gauge shows the pressure difference between the dust side and clean side of the
cartridges. The led indicator helps determine the proper pulse pressure and timer «off» time setting. See page 11.
Position the collector in a convenient location that complies with OSHa and local safety codes. allow access to
the differential pressure sequencer and exhaust damper. Provide ample space at the top and at the front to open
the cover to access pulsating air jet system and the cartridges.
Shorting electrical components could result in serious electrical shocks, or equipment damage. All
electrical work must be performed by a qualified electrician, and comply with applicable codes.
Connect electrical power
NOTE : a schematic for ISTblast cabinets is supplied with the cabinet. after wiring completed, keep the schematics
and manuals together for future reference and electrical replacement parts. Wiring from the user’s disconnect
to the cabinet controls must be provided by the user. Conduit and wiring from the control box (or starter) to the
exhauster motor and 115 volts to the RPC Control Panel (Pulse Sequence Panel), must also be provided by the
user. If the dust Collector replaces an existing «push through» collector or dust bag, the exhauster may be wired
into the control box, to the terminal strip or starter where the conduit from the old reclaimer motor is attached.
Electrical requirements depend on the size and phase of the motor. Standard dust collectors are supplied as
follows:
16000 CFM collectors, 7.5 hp, 230/450 V, 3 Ph, 60 Hz.
WARnInG : Electrical power must be locked out and tagged out before continuing.
