Sentry Air- Walk-In Fume Hoods

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 particulate. Primarily, these hoods isolate the environment from particle contamination and allow applications to be performed in a separate 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.

Types of Walk-in Hoods

Sentry Air Systems offers 3 different kinds of Walk-in Enclosures to allow customers a solution suited for their needs.

How do Walk-in Fume Hoods 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 releasing cleansed air back into the ambient room.

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

Accessory: Walk-in Fume Hood Control Panel

The Walk-in Fume Hood Control Panel provides central control for the system’s air cleaners and LED lights and helps monitor the filter saturation and system runtime. This UL listed system (UL standard 61010-1) controls from 1 up to 4 air cleaners (Model 300 or Model 400 only). The Control Panel offers one master power switch for air cleaners, adjustable LED light controls, and a digital display. The digital display showcases each filter’s static pressure and the system’s runtime. The filter static pressure helps the operator monitor the filter’s saturation and maintain consistent maintenance schedules. The Walk-in Control Panel hardwires into the walk-in fume hood and requires an electrician for installation/maintenance.

Benefits:

• Central fan control for 1-4 air cleaners
• Adjustable LED Lights (up to 2,884 lumens per light)
• Digital display showcasing each filter’s static pressure and system runtime
• Hardwires into the system
• UL Listed (UL Standard 61010-1)
• Made in the USA
