Recirculating Fume
Cabinets are the Future
for the UK’s Laboratories.
LABORATORY managers are being offered
advice and assistance in their search
for high quality fume filtration from the
UK’s leading manufacturer of clean air
solutions.
Monmouth Scientific, based in Somerset,
believe there is a common misconception
that Ducted Fume Cupboards are cheaper
to install, run and maintain than their Non-
Ducted counterparts.
Through the use of Carbon Filters, the
Monmouth Circulaire® range efficiently
filters more than 500 chemicals without
the need for ducting. With the capabilities
of a traditional fume cupboard, the non-
ducted system doesn’t bare the high costs
of exhausting a Laboratory’s conditioned
air, instead, the air is cleaned before being
safely recirculated back into the working
environment.
The Cost Comparison Chart (below)
proves that, when compared to a Fixed Air
Ducted System, a Monmouth Circulaire®
Filtered solution wi ll save well in excess of
£10,000.00 per unit over a 5-year period.
