4.2 Functional description
The DUSTOMAT-S is equipped with a three-phase motor which drives a radial fan.
The vacuum created by the fan sucks in air via the suction hose connected to the intake
port.
A permanent filter (cotton filter bag with an upstream paper bag) separates the dust from
the air. The purified air is guided back into the room through the exhaust slots.
The product is equipped with a manometer as a control device for minimum flow volume.
This control device measures the vacuum developing after the filter. The flow resistance
increases with increased filter soiling from the dust and with it, the vacuum after the filter.
The paper filter must be replaced if the area marked for the suction diameter on the
manometer is reached at the latest.
To dispose of the filled dust collection bag, the upper part can be lifted upwards and the
dust collection bag removed from the device.
4.3 Thorough electrical conductivity
A continuous electrical connection of all easily touchable metal parts which are not a com-
ponent of the electrical operating circuit (thus inactive) is established to earth. Prevents a
high contact voltage on electrically conductive device parts (e.g. housings) in the event of
a fault.
