50 - Dust Control System
Functional Description
The dust raised in the compartment of the main broom, is collected in the rear cargo area by a flow of air
generated by the dust control system
The filter located between the vacuum system and the hopper, retains dirt which is then conveyed through a
feedbox into the hopper itself
The operation of the system depends on the activation of the main broom
By deactivating the main broom, the dust control system turns off automatically
The vacuum system is composed of the vacuum system motor (M1) which is powered by the Main Machine
Controller (EB1)
The vacuum system function is activated automatically when the main broom is lowered with the
corresponding One-Touch button
, it can, however, be turned on or off independently with the vacuum
button
, it turns off when the machine is stopped, when the hopper is lifted and during activation the
electric filter shaker.
The electric filter shaker system is composed of two motors (M2) connected in parallel, which are powered by
the Main Machine Controller (EB1)
When the filter-shaker button
is pressed, the system is activated for a cycle of 20 seconds during
which the motors are powered 0 5 sec ON and 0 5 sec OFF to continuously modulate the number of
revolutions and the resulting vibration frequencies of the filter.
The vibrating motors shake the filter allowing dirt trapped in the folds of the same to fall by gravity into the
hopper
This reduces filter maintenance and helps to maintain proper airflow through the filter.
