Dust Collectors - Series CPV
OPERATION
Principle of operation
Filtering operation (fig. 4a)
With the collector mounted on the silo or storage container, dust-laden air enters
the collector through the aperture at the bottom of the collector. Airflow is directed
upwards through the PowerCore filter packs, removing the fine particulate (heavier
particulate falls back into the process). The clean, filtered air passes through the
collector via the fan (if fitted) and is discharged through the cleaned air outlet.
Cleaning operation (fig. 4b)
At regular intervals, governed by the controller, each PowerCore filter pack receives
a short burst of compressed air from an adjacent air diaphragm valve. This causes
a brief, powerful reversal of airflow through the PowerCore filter pack, effectively
dislodging the dust layer which then falls back into the process.
