Product Description 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: -No costly ducting or venting -No permitting issues for venting outside of the building -Adaptable (mobility and ease in change of layout) -Environmentally friendly -Significant energy cost saving Product Parameters Model Parameters YT-1500A YT-1500B YT-1500C YT-1800A YT-1800B YT-1800C Size (mm) 1500(W)*865(D)*2400(H) 1800(W)*1205(D)*2400(H) Worktop Size (mm) 1260(W1)*795(D1)*1100(H1) 1560(W1)*795(D1)*1100(H1) Worktop 20+6mm Ceramic 20+6mm Ceramic 12.7mm Solid Physiochemical Board 20+6mm Ceramic 20+6mm Ceramic 12.7mm Solid Physiochemical Board Liner 5mm Ceramic Fibre 5mm Compact Laminate 5mm Compact Laminate 5mm Ceramic Fibre 5mm Compact Laminate 5mm Compact Laminate Diversion Structure Back Absorption Control System Touch-Tone Control Panel (LED Screen) Input Power 220V/32A Fan Power Less than 2.8 A Socket Max.

Benefits of a Ductless Fume Hood -Minimal installation costs-no external ducting or venting -Portable -Minimal maintenance -Environmentally friendly -Significant energy cost savings -No permitting issues for venting outside (ie.
