The difference between Non-Ducted and Ducted fume cupboards

Monmouth Scientific challenges the common misconception that Ducted Fume Cupboards are more cost-effective in installation, operation, and maintenance than their Non-Ducted counterparts. The company provides valuable advice and support to Laboratory Managers in pursuing premium fume filtration solutions.

The Circulaire® range employs Carbon Filters to filter over 500 chemicals without necessitating ducting efficiently.

This non-ducted system boasts the capabilities of a traditional fume cupboard while avoiding the substantial costs associated with exhausting a laboratory's conditioned air. The air is meticulously cleansed before being safely recirculated into the working environment.

A comprehensive cost comparison chart demonstrates that the Circulaire® Filtered solution can save well over £10,000.00 per unit over 5 years compared to a Fixed Air Ducted System.

One of the key advantages of the Circulaire® range is its adaptability for installation in challenging locations, such as interior rooms, basements, and even listed buildings, without the constraints or elaborate planning required for attachment to an expensive extract system.

The Non-Ducted units require only a standard 240 V/13-amp connection, making their installation as straightforward as a Laboratory Fridge. Moreover, with a depth of 750 mm, the range is designed to conveniently fit through standard door openings and rest on standard Lab Benching.

Monmouth Scientific's expertise is well-demonstrated through a recent installation of 20 recirculating fume cabinets at the prestigious British Petroleum's (BP) Technology & Research Centre in Pangbourne, Berkshire.

BP’s facility in Pangbourne is the central hub for all their research centers, so for us to install this number of recirculating fume cabinets here showcases the forward-thinking, in terms of clean air solutions, from one of the world’s major corporations.
