Ductwork air balance is essential to the proper operation of a traditional ducted fume hood however, it is also the source of very important energy consumption. In fact, captair® Flex™ filtered enclosures do not generate any energy costs associated with the use of expensive extraction systems or conditioned air supplies. Operational costs remain at a minimum even when taking into account filter changes.
Comparison between a fume extraction cupboard and a Captair recirculating fume hood
Fume extraction cupboard
Energy cost of a fume extraction cupboard (estimated cost per year)
4100 euros
250 euros
Average cost for a pool of 750,000 devices*
3 billion euros
190 million Euros
Electricity consumed by these 750,000 devices
12 250-megawatt power plants
0.8 250-megawatt power plants
An independent study* has shown that the contribution brought by the use of ducted fume hoods with regards to the overall energy consumption in laboratories is far from being negligible. In fact, each ducted fume hood would be responsible for consuming 3.5 times more energy than the average size home. Our molecular filtration technology, based on super-activated carbon, serves mainly to protect the user, but also:
Reduces your environmental footprint.
Reduces operating costs.
Eliminates almost all installation costs.

Since no ductwork is required, a captair® Flex™ filtered enclosure totally eliminates the direct discharge of pollutants into the atmosphere and therefore contributes to the protection of the environment. Furthermore, a captair® Flex™ filtered enclosure does not generate any pollution linked to energy production unlike a traditional ducted fume hood.
The installation of a captair® Flex™ filtered enclosure is quick and easy. There is no need for a ductwork linked to an air supply / air extraction system, in comparison to traditional ducted systems. A single electrical outlet is all that is needed to make it work, its setting up can be realized at any time, without any complex forward planning. Do not hesitate to compare this cost to that of a traditional ducted fume hood.
Captair® Flex™ filtered enclosures can be moved depending on the protection needs of the laboratory and can be easily relocated without disturbing room air balance.
