The Model 440 Industrial Downdraft Bench 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. Sentry Air Systems offers both standard and custom stainless steel downdraft benches that are equipped with a powerful industrial air cleaner and high-quality HEPA filtration media. This filter media is up to 99.97% efficient on particles 0.3 microns and larger and the air cleaner provides up to 700 CFM of air volume [950 CFM is available as an upgrade]. ASHRAE filtration, heavy-duty Activated Carbon, and specialty-blended filter media is also utilized in certain applications.
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. Typical applications include: solvent vapor control, solder fumes, light grinding, epoxy fume control, sanding, buffing, brazing, spray paint, powder control, and a variety of other industrial applications.
Downdraft benches are available with 30” [Model # SS-430-DDB] and 40” wide perforated work areas. Custom design options and modifications can be discussed with a Sentry Air Applications Specialist.
