The Model 435 Portable Downdraft Bench & Table - Standing Height is an effective source-capture solution for the extraction of fume, dust, and smoke at the work surface level. This safety engineering control helps to protect the operator’s breathing zone and surrounding environment from hazardous airborne contaminants. These units are designed for easy portability and flexibility within the work environment. Lockable casters make the unit easy to roll across a room and the no tool filter change design allows quick and easy filter replacement. The standing height configuration is at a comfortable working height when standing in front of the bench.

The powerful Sentry Air Model 400 air cleaner provides up to 700 CFM of air volume to pull harmful fume down into the filter chamber. Our standard HEPA filter media is 99.97% efficient at capturing particles down to 0.3 microns in size. These negative-pressure systems are designed to eliminate costly exhaust systems, reduce energy losses, and aid in employee protection by capturing pollutants at the source of emission. Also available in a sitting height configuration with either a clear or solid doghouse.

Typical applications include: solvent vapor control, solder fumes, light grinding, epoxy fume control, sanding, buffing, brazing, powder control, maintenance welding, and a variety of other industrial applications.

NOTE: Available in a sitting height configuration and also with either a clear or solid doghouse.
