Working principle

Ductless filtering fumehoods with modular filtration column
A ductless recirculating fume hood is a safety device used to protect laboratory workers when handling chemicals that pose an inhalation risk.
These fume hoods are equipped with filtration technology that is specific to the type of products handled. These filters capture toxic molecules and particles evaporated in the chemical handling enclosure and make it possible to:
  • Protect users in an effective manner,
  • Reduce the environmental footprint by not releasing any toxic emissions into the atmosphere,
  • Reduce operating costs due to their very low energy consumption,
  • Eliminate all set-up costs related to the installation of a ducted airflow system. 
Complies with the requirements of ASHRAE 110:1995 and ANSI Z9.5 containment standards
   
1 - Handling openings
Air from the laboratory enters the enclosure through ergonomic apertures. The air face velocity creates a dynamic barrier between the user and the chemicals being handled.		 2 - Handling enclosure
The device ventilation system draws the molecules and particles that have evaporated in the enclosure toward the filtration system. The level of containment provided by the enclosure prevents any pollutants from being released into the laboratory.

3 - Air extraction
The filtration technology customized to the applications in question serves to trap the molecules and particles that have evaporated within the enclosure. The air discharged into the equipment is thus free from all pollutants.
4 - Purification of the ambient air
The recirculation of the filtered air helps to purify the ambient air of the laboratory.
