Envelope
Shaker dust collectors are small, stand alone systems used for localized dust
control. Like the Tube-Type
Shaker System, the Envelope Shaker System and Cabinet Collector have
been around for a long time. This
design includes a series of cloth or felt envelopes which are closed at
the bottom and attached to a tubesheet at the top.
Air filters from the outside in, with clean air passing out of
the bag’s top. Dust is
shaken free after the fan is shut down and drops into a hopper, drum,
or tray. The shaker is
operated manually by pulling a bar or stepping on a pedal.
This system is typically used for grinding, sawing, wood-working, and
other small indoor applications. Usually
the dust collector is attached to a single machine, but multiple ducts
can be run from the larger units. |
