INTRODUCTION
Product information
The dust collector is used for the collection of airborne dust and particulate. Whether
in response to the problem of air pollution, or as part of a manufacturing process, the
dust collector provides highly efficient, continuous, on-line dust collection.
The filter cartridges are the heart of the dust collector. These filter cartridges help
ensure that only cleaned air is returned to the plant environment.
The reinforced dust collector can collect explosive dust without putting people at risk
and with a minimum of structural damage as a result of an explosion, assuming that all
safety guidelines in this manual are followed. For each reinforced model the maximum
Kst value for an inside as well as an outside installation is defined (see spec sheet).
Be sure that the explosive (Kst value) of your dust is always below the maximum Kst
value defined for your dust collector type.
Technical and field support are available from your local Donaldson Torit representative
or distributors to answer your questions.
Function
During operation, contaminated air enters the dust collector through the dirty air inlet
area and passes through the filter cartridges.
Dust is collected on the outside surface of the filter cartridges.
The filtered air flows through the centre of the filter cartridges into the clean air
chamber, where it exits through the clean air outlet and can be recirculated into the
environment.
To ensure the optimal performance of your dust collector it is necessary that the filter
cartridges are cleaned automatically and sequentially.
During the cleaning sequence, the timer energizes a solenoid valve, causing the
corresponding diaphragm valve to send a pulse of compressed air through the filter
cartridges (from the inside outward), removing the collected dust from the outside
surfaces of the filter cartridges.
The dust falls through the hopper into the dust disposal system.
