Ductless Fume Hood

Sentry Air Systems ADVANCED Ductless Fume Hoods offer a portable, easy-to-maintain solution that protects your lab personnel from harmful types of carbon, airborne fumes and chemicals. Typically used in locations where outside ventilation isn't possible or will be costly to install, the ductless fume hood produces a recirculating air pattern filtered through high efficiency air filters and requires no external ducting or venting. Used for a variety of applications, including chemical fume control, powder & dust removal, solvent vapor control, pharmaceutical powder filling, light grinding, acid gas fumes, anesthesia gas containment, epoxy fume control, and many more applications that produce particulate and fume.

These SAS hoods are equipped with a powerful fan that pulls the air in through the hood's inlet and into the filtration system. This system is designed to keep harmful airborne contaminants away from the operator's respiratory zone while they work within the hood. Various filter media is used depending on the chemical vapors/and or particulate that are generated (such as HEPA and ULPA filters, Activated Carbon, or specialty-blended media like ammonia, mercury, acid gas, and aldehyde). Because the air is recirculated, no exterior-ducting or make-up air is necessary when using a ductless fume hood.
