Ducted Fume Hoods
A ducted fume hood is a ventilated enclosure used to protect labs and users from hazardous and respirable fumes, dust, and particulates. By utilizing a ducting system, this exterior-venting exhaust hood is typically used for applications with high volumes of volatile organic compounds, and toxic chemicals, gases, or powders.
Typically, ducted fume hoods act as a "last-resort" physical safety barrier to spills and leaks that could occur during the process of highly variant applications. While they are not a mobile solution to the removal of contaminants, ducted fume hoods can serve as a primary engineering control to severe toxins that cannot be recirculated back into the immediate environment.

Ductless Fume Hood vs Ducted Fume Hood
Ducted fume hoods require ductwork to channel contaminants out of the lab using a fan mounted outside the building. These employ multiple pre-filters, HEPA filters, activated carbon filtration, and a strong fan. They're appropriate when there's a potential for being exposed to high volumes of particulate and toxic fumes. Ducted systems provide a minimal risk of dangerous fumes being recirculated back into the work environment. They are beneficial when the systems are used consistently or when highly toxic substances are in use.
Ductless fume hoods capture and remove contaminants and send clean, filtered air back into the lab without the need for external venting. They require HEPA and charcoal filters. Filter maintenance is more involved when using a ductless system. Filters may need to be changed anywhere from six months to annually.
Description
Sentry Air's Ducted Exhaust Hood integrates high-quality materials and superior design to provide a compact and lightweight exterior-ducting fume hood solution. This benchtop unit features unique hinged folding side panels, a high-density polyethylene base, a clear polycarbonate top, and a polycarbonate hinged sloping front lid. Typically, exhaust hoods are utilized in chemical laboratories- especially when evaporating large amounts of volatile organics, chemicals with low odor thresholds, heavy powder, capsule filling, and a variety of other processes that require exterior fume exhaust.
The Exhaust Hood provides an effective and economical tool for air quality enhancement in many commercial, chemical, medical, laboratory, and industrial applications.
