Downdraft Tables for Combustible Dust Collection, Including Aluminum Dust Collection

DualDraw Downdraft Tables for Combustible Dust Collection are designed to capture hazardous combustible dust, including aluminum dust, in a cost-effective, easy-to-maintain manner.  For the industrial dust extraction system line, we start with the look and feel of the BG Series with its signature vented back stop and downdraft design.  Using design guidelines as outlined in the NFPA Combustible Dust standards such as NFPA 484, 654, and 664, our downdraft solutions are then configured specifically to help customers address the hazardous and often costly process of containing airborne combustible dust.

How to most cost-effectively and safely contain combustible dust is an often-debated topic.  Regulations vary widely depending on where in the world your facility may have its physical address.  Enforcement agencies often provide conflicting guidance on the best approach to control dust hazards.  Regardless of the confusion surrounding its regulation, the fact remains that airborne combustible dust is extremely dangerous when left unaddressed and that many lives have been lost from explosions directly related to its presence.

What is the DualDraw approach? Our non-spark design and compact air filter area on each industrial dust extractor significantly mitigate the hazard associated with combustible dust. Additionally, our careful selection of the proper air filter type based on the details of a customer’s particular application is critical. Finally, we consult closely with our customers to ensure there is a solid understanding of what is involved in owning a combustible dust (like aluminum) collector. For example, customers must have a clear hazard communication program and establish rigorous housekeeping routines to ensure industrial dust extraction systems are kept in optimal condition with no possibility of fugitive dust build-up.

Our patented designs, combined with specific operational protocols, show how many DualDraw customers are currently safely addressing their combustible dust hazards. See below for some of our more popular industrial dust extraction system models and some details about available accessories and options.

Standard Configuration Options and Accessories:

1. The standard depth of the industrial dust extractor is 30”. Can be increased in 5” increments, please specify.
2. Non-spark build includes a work surface, side wings, and a vented backstop. Fan wheels are AMCA Spark Class B design.
3. Non-spark work surface consists of C-Channel grates, reinforced for strength. The average table capacity is 500 to 750 lbs, which can be increased if required.
4. Standard components of this industrial dust extractor include a pressure gauge to monitor filter cleanliness, a NEMA 12/4X thermally protected manual motor starter, and an easy-access clean-out tray.
5. Standard electrical options for the aluminum dust collector are 115/230V single phase or 230/460V three phase.
6. Fan, motor, and air filtration sub-systems are located under the work surface inside the body of the industrial dust extractor (internal space saver) or attached to the back of the unit (as shown above) as a separate sub-system. If attached to the back, the unit complies with ADA requirements for sitting operators and adds approximately 20” to the depth of the unit.
7. Standard air filter configurations include pleated prefilters and pleated final filters for aluminum dust collection. HEPA filter option available.  No self-cleaning cartridge style is available for this model given the related combustibility concerns.
8. Standard options and accessories include but are not limited to the following: hazardous duty Class II, Division I motor, heavy-duty caster wheels, soft top non-marring work surface, light kit, variable frequency drive (VFD), heavy-duty work surface, custom powder coat epoxy paint finish.
