Fume cupboards (fumecupboards) are designed for exactly
that, the extraction of fumes. Unlike microbiological safety cabinets (msc) fume cupboards do not
generally exhaust through hepa filtration (although in exceptional
circumstances they may be required to). Designed to exhaust fumes from the local environment traditionally to atmosphere through large diameter upvc (plastic) ducting although increasingly, for routine, lower volume work recirculating units are specified where the fumes are adsorbed and retained in special typed carbon filtration and vented directly back to the local area - if in doubt about your requirements we offer a free advisory service, simply complete and return our chemical usage sheet and we'll advise you of your fumecupboard options. Traditional British designed fume cupboards (BS7258) often incorporate a bypass grille which reduces the effect on the fume cupboard's face velocity when the sash height is increased or lowered whereas the traditional Nordic design and many school usage type fume cupboards are of a less complicated design without any such bypass system. Material of manufacture can be of either Glass Reinforced Plastic (GRP) or painted metal (stainless or carbon) often determined as to what the fume cupboard is to be used for. A wide variety of optional service fittings can be specified with, for example water and gas being all but the norm in a ducted cupboard but seldom required on a ductless carbon filter type. Important consideration: A ductless fume cupboard is not a direct replacement for an externally ducted one - rather a complementary product to it - complete our chemical usage sheet and we'll advise if a ductless fume cupboard is a viable option for your application. Recirculating fume cupboards are becoming ever more popular but these should not be confused with traditional ducted units as their performance is not comparable like for like. Follow > LINK to our free fume cupboard usage data sheet which we recommend is completed if you are thinking of purchasing a recirculating unit. Safety Cabinet Solutions Ltd offer a full service and maintenance service for both ducted and ductless fume cupboards.
