Donaldson Company, Inc.
Operation
During normal operation, dust-laden air enters the
DB-800 through the slotted-steel work surface. Heavy
particulate falls into the dust drawers and fine particulate
collects on the outside surface of the filter bags. Clean,
filtered air passes through the center of the EZ Filter
Pack™ into the clean-air chamber, and discharges
through the clean-air outlet.
The DB-800 is an intermittent-duty collector, which
means that filter cleaning cannot start until the fan is
turned OFF and fan rotation has stopped. Pushing down
on the hand- or foot-operated shaker pedal and releasing
rapidly six times completes manual filter cleaning. The
releasing action causes the dust cake to fracture and fall
into the dust storage area.
