For Sale ESCO The Airstream Ductless Fume Cabinet Fume/Bio Safety Hood

Ductless fume cabinets provide operator and environment protection from toxic vapours, gases and fumes. The inflow moves from the ambient environment into the work zone through the cabinet front opening, with an average velocity of 0.5 m/s or 100 fpm. Additional inflow air taken through the AutoPurge™ perforations at the back of the work zone prevents fume accumulation for better operator protection. Negative pressure is created in the cabinet’s work zone, which ensures operator protection. The inflow flushes the entire work zone of the cabinet; within the main chamber of the cabinet, negative pressure (relative to the ambient environment) is maintained in order to ensure that no chemical fumes or vapours escape the work zone. Air is taken through a prefilter and an activated carbon filter mounted in the interior; The prefilter is in built with the activated carbon filter, which helps prolong carbon filter life by removing large particulates before the they enter the carbon filter. The carbon filterremoves all fumes from the exhaust air stream; filtered clean air is exhausted directly back to the room from the top of the cabinet. The ductless fume cabinet can be remotely exhausted to the external atmosphere via an airtight hard ducting system (optional), the cabinet provides protection for the operator from volatile toxic chemicals used in trace amounts, which normally would not be removed by the exhaust ULPA filter.
