During normal operation, dust-laden air is drawn into the collector through a duct connected to the inlet box, near the top of the

collector. The dust-laden air is then directed downward through the collector body where heavier dust falls directly into the hopper.

air passes into the clean-air plenum where it is drawn through the fan and is discharged through the clean-air outlet.

Dust and fume reaching the base of the collector is directed into a dust bin where it can be removed easily without the need for

tools.
