Downdraft Booths

Self Contained Collection Hoods Using DualDraw ® Airflow Technology

DualDraw Downdraft Booths are an air filtration solution designed for protection of you and your operators through the maximum containment of airborne particles.  Critically, downdraft booths also eliminate cross-contamination of plant equipment and processes. Our down draft booth models incorporate the patented DualDraw airflow design of the perforated surface and vented backstop with a flexible panel filter system configured to the operator application.

The downdraft booth design offers one of our most protective approaches to dust and fume control, making them a solid choice when dealing with particularly hazardous applications.  For example, spray painting should always be performed in a well ventilated area.  When used as a downdraft paint booth, these self-contained solutions using activated carbon filtration protect operators and other workers in a facility from the risks of respiratory conditions as a result of inhaling paint fume.

The DualDraw approach to quality and performance of downdraft booths is unique in the marketplace. We guarantee your satisfaction no matter what filtration systems you need. Contact us today.

Characteristics Patented DualDraw design: even distribution of airflow across a perforated surface and vented back stop. Modular fastening system provides design flexibility to meet customer requirements in a cost-effective manner. Self contained solution; no outdoor exhausting necessary.
Filtration Systems Filtration systems attach to the back side of equipment or are located internally. Choose between dust collection, smoke or fume removal, and HEPA filtration. All filter systems in our downdraft booths come with cleanout trays and easy to remove access doors for filter maintenance.
    • Dust Dust filter housings are modular and attach to the back of the unit. Dust filter housing dimensions are 24” D x 24” W x 80” H. Cleanout tray for ease of maintenance.
    • Smoke/Fume Smoke/Fume filter housings are modular and attach to the back of the unit. Smoke/Fume filter housing dimensions are 24” D x 24” W x 48” H. Cleanout tray for ease of maintenance.
    • Internal Internal filter systems are located inside the downdraft paint booth and accessed through a door located on the bottom front. Internal filter systems reduce overall depth by 24” and are a practical solution when space is limited. Cleanout tray for ease of maintenance.
    • HEPA HEPA filter systems for dust, smoke, or fumes are available. HEPA systems can also be located internal. Cleanout tray for ease of maintenance.
Available Sizes Standard lengths of downdraft booths are 36”, 48”, 60”, 72”, and 96”. Standard depth of the work surface is 30” and standard height is 80”. Table footprint extends an additional 24” D to account for the filter housing. Flexible design construction allows customers to cost-effectively specify non-standard sizes.
Work Surface Area  The standard surface area of a DualDraw downdraft paint booth ranges from 7.5ft2 to 20ft2. The surface of the equipment is a series of 5” W perforated C-channel grates. Each grate has evenly spaced 1/2” x 3/16” perforations that create an equal distribution of downdraft across the surface.
