DUST CONTROL SYSTEM

FUNCTIONAL OVERVIEW

Dust Control System
A dust control system is used to contain and filter the dust that is created when sweeping. In general, the dust control should always
be on when sweeping except when there is water on the surface being swept. A hydraulic impeller motor with a fan mounted on it is
used to create airflow through the hopper system. As the air moves through the hopper the dust is lifted and then trapped in the filter.
The filter assembly has a shaker motor mounted on it that is used by the operator to clean the filter when the machine is in use.
Hydraulic oil flows to the impeller motor from the front gear pump of the auxiliary pump. The dust control/shaker switch S7 is used to
energize the dust control solenoid L2 in the on position or the shaker relay K2 in the momentary position. There is an optional hopper
temperature switch S6, which will open if the hopper temperature exceeds 140° F, and break the circuit to L2 while lighting the
temperature indicator H5. The shaker motor has an optional timer E1 that will keep the coil of K2 energized for fifteen seconds when
S7 is turned off.
