Downdraft Tables and Benches
Dust and fume generating work areas within a facility can often be controlled with self-contained and moveable downdraft tables and downdraft benches. Tables can be designed for tabletop downdraft only or combined with a back-draft airflow and top enclosure design for nuisance dust capture. Micron size and loading of collected particulate, smoke, and fume will determine the filtration systems selected; available options available include throw-away filters, pulse clean dust collectors, or wet collectors. Many standard sized tables and benches are available but custom-designed units are a specialty. We’ll make the bench to meet your production requirements!
Enclosed Downdraft Table
Enclosed Downdraft Table
Custom Downdraft Bench for use with Ink blotting and film printing - Unit is provided with a clear sash to be pulled down during testing and fully open for the cleanout and change out of equipment. Utilizes a carbon and HEPA filter combination for fume and dust control, with an option for duct connection for more hazardous materials. Includes backdraft design and top enclosure with side table for additional workspace.
Downdraft Table
Downdraft Table
Tables are designed for unobstructed tabletop work surface with collected particulate captured in an integral filtration section. Operators will work on both sides of the able simultaneously without impeding work operations. Units can be configured with different fan packages for higher airflow requirements.

Custom Downdraft Tables on Film Testing Reels - Units have custom control panels, vibration mounts due to machine high-speed operation and requirement for validation testing of customers equipment and top-mounted exhaust fans. Units are designed to be mounted on worktables supplied by client.
Downdraft Table With Integral Dust Collector
Downdraft Table With Integral Dust Collector
Wet Dust Collector with Downdraft Benchwork surface - Dual Draw downdraft unit has front access door for sludge removal when used on explosive and hazardous materials. Bench meets requirements for Metal Dust in NFPA 484 “Standard for Combustible Metals.” The design utilizes a purge fan to run 24/7 to negate the buildup of Hydrogen in the unit when not collecting materials. A custom Control Panel is part of the assembly.
Bench with downdraft and backdraft exhaust
Bench with downdraft and backdraft exhaust
The unit has adjustable side shields for oversized workpieces. The bench is dedicated to aluminum grinding work only. It incorporates a spark resistant aluminum design, hazardous duty motor and static filtration with strict changeout procedures to mitigate risks of working with aluminum in a dry environment.

Donaldson Torit DB-3000 Downdraft BenchTitle: Downdraft Bench with Reverse Pulse Jet Filtration - Donaldson Torit DB-3000 unit has side shields and top shelf for overhead lighting. Tabletop is reinforced for heavy workpieces and an integral filtration section is a pulse clean cartridge dust collector for heavy dust loadings.
Downdraft Tables
Downdraft tables are ideal for those dust that are heavy and tend to fall onto the surface of the table. Their effectiveness is augmented with side and back shields and backdraft exhaust. They can be assembled as a bench or booth to improve the workspace function and can be designed wheelchair accessible. It must be pointed out that open tabletop units are susceptible to cross drafts and side shields are strongly suggested. HVAC supply duct, window openings, or man coolers can disrupt the capture of light heat generated smokes and fumes that rise from the tabletop.
Downdraft Benches
Dust containment benches isolate those processes where pollutants may be blown away from a capture point and dispersed around the facility by cross drafts, man coolers, compressed air, or by rotating equipment like sanders and grinders. These benches are downdraft tables with encapsulating tops that contain dust and fume and add additional features of directed airflow and visibility for the operator. Lighting is an important option for those projects requiring close inspection.
Why a Downdraft Table or Bench?
- Moveable
- Free of cross drafts (with side and back shields)
- Isolate dusty operations within a large facility
- Cost-effective verses a ducted dust collection system
- No overhead exhaust duct obstruction
- Readily available design modifications to encompass workpiece and maximize capture
- Customization to a specific process requirement is easy
- Alternative dust collection removal efficiency
Important Options for Downdraft Tables and Benches
- Filtration of captured particulate by way of a continuous duty pulse cleaning dust collection or a bank of replaceable throwaway filters
- Side shields to prevent cross drafts
- Both downdraft and backdraft options
- Custom designs to fit tight space envelopes
- Lighting for visibility
- Wheelchair accessible (Americans with Disabilities Act compliant)
- Wet collection is available for explosive dust
