  • Ductless fume cabinets provide operator and environmental protection from toxic vapors, 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, with no outflow created to compromise operator safety.
  • 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 so that no chemical fumes or vapors escape the work zone.
  • Air is taken through a pre-filter and an activated carbon filter mounted in the interior. The pre-filter is built-in with the activated carbon filter, prolonging carbon filter life by removing large particulates before the they enter the carbon filter. The carbon filter removes 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 a non-airtight thimble ducting system (optional), providing additional protection for the operator from volatile toxic chemicals used in high amounts, which normally would not be completely removed by the exhaust filter.
