Walk In Hood | Sentry Air Systems

Walk-In Fume Hoods, manufactured by Sentry Air Systems, are designed to isolate a work process within a larger workspace so as to not cross contaminate between various applications. These enclosures are the ideal way to remove fumes, dust, vapors, and odors generated from oversized machinery or applications that are too large for benchtop fume extraction solutions.

What is a Walk-In Fume Hood?

Walk-In Fume Hoods are "oversized" enclosures that are built to seclude the exterior of the hood from fumes, dust, odors, and other harmful particulate. Primarily, these hoods isolate the environment from particle contamination and allow applications to be performed in a sperate working area.

Also referred to as machine enclosures, these containment systems are used for a variety of applications including data recovery, tissue culture, drum and bin storage, botany, pharmaceutical, light grinding, sanding, and other applications that produce hazardous particulates and fumes.

How does a Walk-In Fume Hood work?

While Sentry Air Walk-in Enclosures have several customizable features, the traditional design includes four structural supports, clear panel curtain walls, and a ceiling panel with mounted ductless air filtration units.

The curtained wall doubles as the entrance and exit to the enclosure as well as acting as a barrier surrounding the enclosure. The structural supports maintain the integrity of the enclosure while supporting the weight of the ceiling panel and filtration units. The filtration units utilize powerful fans to create negative pressure that then pulls fume, dust, and vapor from within the enclosure into the units’ filter chamber before exhausting cleansed air back into the ambient room.

A mini “cleanroom” environment can be created within the enclosure by utilizing positive-pressure filtration units atop the ceiling panel. In this scenario, ambient air is pulled into the units’ filter chamber where dust and particulate are captured (99.97% down to 0.3 microns) before exhausting cleansed air into the enclosure work area.

Fume Hood Safety Considerations

Safe operation of your fume hood is critical to aiding in protecting your staff and anyone around (or in) it. A walk-in fume hood should only be considered for use in labs with low hazard chemicals.

They should be visually inspected frequently
Pedestrian traffic in front of the hood should be limited
If your fume hood is used often, a regular cleaning schedule should be established
