Dalamatic Insertable Dust Collectors – Series DLM V
GENERAL SAFETY REQUIREMENTS
It may be necessary to provide a facility to shut down the equipment in
the event of an explosion.
Part of the risk assessment on possible ignition sources for dust and
gas mixtures with very low MIE, has considered the electrostatic risk
from cone discharges. Here the basis of safety is based on using a
conductive bin, dusts with a median particle size of less than 400µm
and advising frequent emptying.
You may wish to consider the use of a sprinkler system when handling
explosive or flammable materials.
None of the fan assemblies can be considered to be a fully sealed
design, indeed most are arranged with either an open inlet or an open
outlet. For this reason, the internal and external atmospheres can be
considered the same in terms of any potentially hazardous classification.
Standard fan assemblies should not exceed 3000 rpm (50 Hz supply)
on systems fitted with an inverter drive.
The filtration media is suitable for filtering particulate only (and not gas).
Some applications are prone to risk of fire. This risk can be reduced by
regular pulse cleaning.
•
Any extinguishing technique and material used must be suitable for
the flammable nature of the dust.
•
A water sprinkler system can be fitted as a special option.
Materials handled by the dust collector may be hazardous (e.g. toxic).
Conduct a Risk Assessment to ensure correct technique is employed.
The dust collector should be cleaned and put into a safe condition prior
to decommissioning. All equipment decommissioning/removal is to be
executed in a manner consistent with applicable codes, regulations and
sound engineering practice.
