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.
