Walk In Fume Hood

Walk-in fume hoods, or enclosures, 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. Additionally, walk-in fume hood enclosures can be designed to create mini “cleanroom” environments for applications that are more sensitive to ambient dust and particulate.

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.

Walk In Fume Hood benefits and features

Economic Room Enclosure Solution. The costly expense of adding fully enclosed rooms for single-purpose applications makes utilizing a walk-in enclosure an excellent, economical solution for creating a separate “clean” or “dirty” workspace within a larger room.

Customizable. Your work processes and space requirements are unique, which is why Sentry Air Walk-in Fume Enclosures are fully customizable. In addition to custom size dimensions*, the modular design of our walk-in enclosures allows flexibility between ductless or ducted fume exhaust. Additional custom options and accessories include: Floor mounting, Clear Anti-Static Vinyl Strip Curtains, a Floor Panel made of High Density Polyethylene, Multiple Filter Units, Exhaust Collars for Ductwork, Quick-change Pre-Filters, and Remote Control Operation.

*Heavy-Duty Steel Frame – Up to 20’ W x 20’ D x 9’ H
Lighter Aluminum Frame – Up to 6’ W x 6’ D x 6’ H

Easy to Assemble and Move. No professional installation is required to assemble a Sentry Air Walk-in Enclosure. This means less down time for your work processes. Additionally, the lightweight materials allow for fairly easy relocation within a general workspace.

All specifications are nominal and subject to change without notice. Not intended for explosive or highly flammable applications. (i.e. when the Lower Flammability Limit is exceeded for any given chemical). Please consult the specific MSDS for questions regarding flammability limits.
