This 18” Wide Ductless Fume Hood is one of the most compact fume containment hoods on the market. This ductless hood is designed to protect both the operator’s respiratory zone and environment from hazardous fumes, vapors, or particulate generated from applications performed within the hood. Despite the small exterior footprint of this hood, the interior working space provides a comfortable and spacious environment for operators performing a variety of processes.

The small structure of this system makes it an ideal solution and addition to a lab or room that has limited space or requires only a small containment area. This light-weight system has also been used in a variety of time sensitive field-testing applications that require transportable equipment. Other uses for this fume hood include chemical fume control, epoxy and solvent fume control, pharmaceutical compounding containment, soldering applications, dust removal, biological applications, and many more processes that require the removal of fumes and dust.

This system utilizes an energy-efficient fan to pull fumes and particulate from the work area of hood into the filter chamber, which is composed of a variety of filter media that is selected depending on the application being performed. This filter media includes HEPA [up to 99.97% efficient on particles 0.3 microns and larger], ASHRAE [up to 95% efficient on particles 0.5 microns and larger], ULPA [up to 99.9995% efficient on particles 0.12 microns and larger], Activated Carbon, and specialty-blended filtration [i.e. Acid Gas, Mercury, Aldehyde, Ammonia]. The 18” Compact Ductless Fume Hood can provide an effective and economical solution for many commercial, medical, laboratory and industrial applications that require a relatively small containment area. Transparent hood material and other custom options are available upon request.

Testimonial from University of California, Davis
(Shown with Outlet Plenum)
"I am using the Sentry Air unit to conduct tissue extraction in an outdoor field setting. I work with a very powerful fixative solution that I use when I extract brain tissue, and the unit has proven to be both protective and efficient in containing the chemical within the hood. The system is also portable and easy to move, which has proven to be of great importance as I move between field sites frequently. Assembly and disassembly is very simple, and the unit has proven to fit my needs as a molecular biologist working outdoors under a variety of conditions, be it changing weather or terrain. I would highly recommend this fume hood to any biologist or chemist that requires protection and portability, as it has proven to be both durable and reliable."
