Dust Control/DustGuard™ Systems
Functional Description
Overview
The dust control system pulls air through the hopper and through a lter to trap the dust from the hopper.
The optional DustGuard
™
system sprays a ne 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 ltered air through vents in the
Hopper Cover.
An optional dust control lter switch will shut off the
vacuum motor in the Impeller Assembly if the vacuum on
the clean side of the lter 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 lter 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 airow through the Filter. The Filter
Shaker Assembly
will automatically switch on when the
sweep system is turned off.
