SECTION 1
DESCRIPTION OF THE CABINET
The Circulaire range of filtration fume cabinets have been designed to provide
operator and environmental protection.
The cabinet provides an inflow air velocity of >0.5m/sec through the working
aperture to provide operator protection.
The standard C550, C650 and C900 units have a two-stage filter system.
The contaminated air is passed through an electro-statically charged pre-filter to
remove coarse particulate, then through a deep bed activated carbon main filter
to remove chemical contaminates. The clean air is re-circulated back to the
laboratory.
When installed correctly the cabinet complies fully with international standards
including BS7989: 2001 for filtration fume cupboards.

The cabinet must be positioned and used on a bench.
An optional stand or under-cupboard and GRP spillage tray can be supplied.
The cabinet may be fitted with Activated Carbon filters suitable for use with a
wide range of pollutants including hydrocarbons. Activated carbon can be
impregnated with chemicals to neutralise many types of contaminants.
See the section on Filter Selection for further information.
For use with particulates, a 99.997% eff. @ 0.3 micron particle size HEPA main
filter should be fitted. Please contact Monmouth Scientific for further information.
