The Basic Ductless Fume Hood, manufactured by Sentry Air Systems, offers 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.
A ductless fume hood is a stand alone, compact workstation that provides a continuous flow of air that filters hazardous fume vapors out, recirculating clean air back into your working environment. Because the air is recirculated, no exterior ducting or makeup air is necessary. These air filtration systems are designed to keep harmful airborne contaminants away from the operator's respiratory zone while they work within the hood.
Also referred to as exhaust hoods, these containment systems are used for a variety of applications including chemical fume control, powder and dust removal, solvent vapor control, pharmaceutical powder filling, light grinding, acid gas fumes, anesthesia gas containment, epoxy fume control and other applications that produce hazardous particulates and fumes.
Ductless fume hoods offer several key advantages when weighing your options versus a ducted fume hood:
However, a ductless fume hood may not be suitable for the application being practiced as there are certain features of a ducted hood that may suit your needs more:
Safe operation of your fume hood is critical to protecting your staff and anyone around it. A ductless fume hood should only be considered for use in labs with low hazard chemicals.
