Ducted 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 or carbon filtration (although in exceptional
circumstances due to local site rules they may be required too). Designed to exhaust fumes from the local
environment generally to atmosphere through large diameter UPVC (plastic) ducting
terminating 3 meters above the height of the building. Increasingly, for routine, lower volume work
recirculating carbon filtered units are specified where the fumes are adsorbed
& retained in special typed carbon filtration and vented directly back to the
local environment - if in doubt about your requirements we offer a free
chemical advisory
service, simply complete and return our chemical
usage sheet and we'll advise you of your fumecupboard options.
Our British designed &
manufactured (BS7258
- EN14175) fume cupboards incorporate a bypass grille
which reduces the effect on the fume cupboard's face velocity when the sash height is
raised or lowered whereas the traditional Nordic design and many school
specific
type fume cupboards are of a more simple 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, for example water and gas being all but the norm in a ducted fume
cupboard but seldom required on a ductless carbon filter type.
Another consideration when looking at a
ducted fumecupboard is the fume cupboard's make-up air requirements, as the
fumecupboard's air is expelled to atmosphere this needs to be replaced by
one means or another.
