Rating and Specification 

Information

General rating and specification information can be 

found in the product literature provided with the collector 

or available on the Donaldson website. For specific 

load values for a collector, see the Specification Control 

Drawing shipped with the collector. 

The Downdraft Bench, Model DB-800 is a self-contained, 

intermittent-duty dust collector with envelope-style 

filters. Designed as a workstation for grinding, polishing, 

hand sanding, and dry buffing applications, the DB-800 

features cotton sateen filter bags, prewired controls, and 

a fluorescent light fixture.

Direct-drive, forward-curve fan provides 200-fpm 

minimum face velocity across the slotted-steel work 

surface designed to hold up to 50-lb per square foot. 

Hinged side panels open to accommodate larger work 

pieces and a manually operated filter shaker allows 

on-demand filter cleaning. Replace filters easily with the 

one-piece EZ Filter Pack™ and dispose of dust contained 

in the dust drawer from the front of the unit.

The Downdraft Bench provides excellent efficiency on 

nuisance dust generated in industrial operations, such as 

grinding, buffing and polishing without rouge, and hand-

sanding operations.

Grinding: The Downdraft Bench has a baffle that limits 

particles from directly impinging with the filter bags 

reducing the risk of bag damage. 

Buffing and Polishing: Buffing and polishing operations 

without rouges. 

Hand Sanding: Light-duty hand sanding only. Avoid 

applications with explosive dust or welding operations.

Explosive Dust: Not intended for use with explosive dust.

Welding: Not recommended for welding operations 

due to the natural tendency for weld fumes to rise and 

Downdraft Benches develop a downward airflow. Use 

the Donaldson Torit Weld Bench in these operations.

Description

Purpose and Intended Use

Misuse or modification may result 

in severe personal injury and/or 

property damage.
