High Performance Fume Hoods
The need to protect personnel from potentially harmful vapors and airborne particulate matter is a fact of life for every modern laboratory. Laboratory Fume hoods are ventilated workstations designed to contain hazardous fumes and exhaust them away from the researcher. Traditional fume hood designs have relied upon high airflow volumes and face velocities to create a “vacuum” effect within the hood chamber to purge the hazardous vapors. Controlling the airflow throughout an entire laboratory facility based upon the requirements of these fume hoods is costly, complicated and inconvenient – and Lab Crafters saw a better way.
The Lab Crafters Air Sentry® rethinks the concept of fume containment by applying principles of fluid dynamics and advanced design features to control the airflow pattern within the hood, along with an integral safety control system built onto the fume hood to provide the safest research environment under the widest range of laboratory conditions. The Air Sentry’s efficient design and reduction in exhaust airflow volume typically reduces laboratory fume hood operating costs by half. Air Sentry is the most technologically advanced fume hood on the market and has been proven, time and again, to significantly outperform the competition in terms of both containment and guaranteed energy savings.
The Air Sentry’s Vortex Chamber design is mathematically and aerodynamically correct, optimizing the flow of the vortex within the hood for maximum containment at lower exhaust volumes and face velocities.
The Vortex Controls measure the stability of the vortex airflow pattern within the hood chamber and automatically adjust the articulating baffle to maintain maximum containment. The digital fume hood monitor provides the user with a display of the fume hood operating conditions, as well as communication with the building automation system.
The Air Sentry’s uniquely designed Baffle pivots to reposition all three of the slot openings when it is adjusted by the Vortex Controls.
The Air Sentry’s Air Foil sill features a multi-slot design, which dynamically directs an airflow pattern over the work surface, reducing turbulence in the bottom area of the fume hood chamber.
The Post Foils allow for the streamlined entry of air into the fume hood around the side posts creating laminar flow jet streams along the fume hood interior side walls.
