Collector Body
The combination of the Dirty and Clean Air plenums along with the hopper represents the total collector body.
Leg Pack
The leg structure supports the collector body at an elevation to accommodate various dust disposal devices and systems which
can be configured to meet customer needs.
Clean Air Plenum (CAP)
Air passes through the filters and into the Clean Air Plenum(CAP) where it exists through the Clean Air Outlet.
Tubesheet
The tubesheet is the metal panel the filters are sealed against to separate the Dirty Air and Clean Air Plenums of the collector.
Through holes are cut to mount filters.
Clean Air Plenum (CAP) Door
The Clean Air Plenum (VAP) door allows access into the Clean Air Plenum for service and inspection.
Dirty Air Plenum (DAP)
Dust laden process air enters the Dirty Air Plenum via the involute scroll inlet. As air enters it goes through a preseparation stage
and then airflow straightening before it reaches the filters. This allows the majority of the dust to drop out into the hopper and the
airflow to be evened out before it gets to the filters.
Hopper
The hopper, located at the bottom of the collector body, is the discharge point for dust that has been preseparated and pulsed off
of the filters.
Arm Drive
The arm drive consists of a gearbox, motor, tensioner, sprockets, and chain. This rotates the arm around the centerline of the
collector to distribute the cleaning air.
Sweep Arm Assembly
The sweep arm assembly is a “Tee” or “L” shaped assembly with nozzles along the bottom to distribute the cleaning air into the
filter bags. The arm assembly rotates around the centerline of the collector.
H Frame
An “H” shaped structure that supports the reverse air cleaing system.
Hopper Outlet
The hopper outlet is a singular outlet at the bottom of the hopper where the separated dust exits the collector and is routed to
be disposed of via bin, pneumatic conveyor, screw conveyor, or other means. A rotary airlock is typically used to isolate the dust
collection system from the dust disposal system.
