The Captair Flex filtering fume hood guarantees that you are protected when working with chemicals that pose an inhalation risk for the user.

The fume hood functions based on the recirculation of filtered air, which makes it possible to use high-efficiency filters to trap toxic particles and molecules and to recycle this air within the laboratory. The air downstream from the hood’s modular filtration column, which uses the Flex technology, is thus free of all chemical pollutants.

By combining molecular and particulate filtration technologies, Erlab was able to devise the new Flex modular filtration column technology. This single device can thus be configured to meet the protection needs of your laboratory. This flexibility was made possible by creating stackable, one-size-fits-all filtration cartridges—an innovation that is key to your new Captair Flex. This innovation developed by the Erlab R&D laboratory offers unprecedented flexibility, adaptability, and savings. Your device can be quickly reconfigured and can be easily used for other applications.

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 a traditional ducted fume hood cost.

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.

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.

Some of the benefits of Captair hoods include it being completely ductless and requiring no special installation; high-efficiency filtration, protecting the lab technician; exhausts no pollutants to the outside; purifies air in the room at a rate of 98.29 cfm; it’s compact size lends itself to being mobile with the ability to be set up anywhere in minutes; and it’s economical, in that it does not consume heated or cooled air.
