Examples of Potential Ignition Sources
Grinding dust from ferrous metals
Hot ash or sparks from any source
2. Unless the equipment was originally designed for collection of explosive material and proper
disclaimer on record this equipment must not be used for the collection of any materials where
there is a risk of explosion. Pressure relief vents or explosion vents must not be applied to the
equipment or adjoining systems.

Introduction
DIVERSITECH Weld Booth Dust Collectors are designed to filter out solid particulate and dusts
such as Weld fume and grinding dust. The cleaned air is then returned to the work space to
eliminate the need to exhaust treated air. Once the unit is mounted, connection of electrical
power and compressed air complete the installation.
Note:
If the unit has the optional fire suppression system please refer to the Fire Trace
Manual and Smoke Detector manual for maintenance information.
Explanation of Operation
During normal operation, contaminated air is pulled through the top section of the cartridge
collector cabinet. The cabinet design distributes the contaminated air uniformly across the
vertically arranged filter cartridges. A portion of the dust will collect on the surface of the
cartridge media as the dust free air passes through the media, through the vertical venturi,
into the horizontal clean air duct and to the blower for return to the work space. The dust that
collects on the cartridge media will be repelled into the downward air flow by the reverse jet
pulse cleaning system. This is controlled by a digital pulse control. At prescribed times a brief
burst of compressed air will be released to a row of cartridge filters, fired upwards through the
vertical venturi, into the core of the cartridge filter to impact the dust away from the filters
surface. The dust is caught by the downward flow and once again moved towards the settling
chamber. The dust drawer of the DIVERSITECH Collector contains no airflow inlets or outlets. In
fact, airflow is never close to the dust drawer. This eliminates the possibility of re-entrainment
of the dust once it gets into this section of the dust collector cabinet.
