Gas extraction hoods are equipment designed to protect the user, from chemical exposures and dangerous agents, during the study processes. The protection is achieved by the ventilation systems of the interior space, by an air flow caused through an adjustable working principle, also avoiding the discharge of pollutants into the environment.
This equipment addresses the need to control dangerous or irritating substances that are usually generated in the air, or released within the local ventilation device itself. According to this, gas extraction campaigns are used in chemical laboratories, where the user is exposed to pollutants, dangerous chemicals, etc., since it is an area equipped with the necessary means to carry out research, experiments, practices and scientific work.
