Dust Control/DustGuard™ Systems
Functional Description
Overview
The dust control system pulls air through the hopper and through a filter to trap the dust from the hopper.
The optional DustGuard
™
system sprays a fine stream of water in front of each side broom to minimize the
dust created by the main broom.
Dust Control System
The
Impeller Assembly
, mounted in the
Hopper Cover
, pulls
air from the
Upper Hopper
through the
Filter
which traps
the dust generated by the sweep system. The
Impeller
Assembly
exhausts the filtered air through vents in the
Hopper Cover
.
An optional dust control filter switch will shut off the
vacuum motor in the
Impeller Assembly
if the vacuum on
the clean side of the filter gets too high as a result of a
clogged
Filter
. When the switch is activated, the LCD will
display an icon to the operator.
The removable
Filter Shaker Assembly
vibrates the
Filter
when the filter shaker switch is pressed to shake large
particles from the input side of the
Filter
back into the
hopper. This reduces
Filter
maintenance and helps
maintain adequate airflow through the
Filter
. The
Filter
Shaker Assembly
will automatically switch on when the
sweep system is turned off.
