The Model 300 Winged Sentry is a benchtop fume extraction unit that offers a unique design and horizontal airflow pattern. It features infinitely adjustable “wing flaps” to assist in directing contaminated air towards the unit’s inlet and into the filter chamber while the operator works between the wings. This system offers hood-like containment without the confinements of working within an actual hood. The operator can place these wings in the most effective position for their application, or they can be placed flat against the sides of the unit to conserve space. This system offers a standard variable speed controller and an optional clear, hinged acrylic lid (SS-300-WSL) for those seeking further containment.
Appropriate filtration media is selected for the Winged Sentry based on the application being performed by the operator. HEPA [up to 99.97% efficient on particles 0.3 microns and larger], ASHRAE [up to 95% efficient on particles 0.5 microns and larger], Activated Carbon, and specialty-blended filter media [i.e. Acid Gas, Mercury, Aldehyde, Ammonia] are the most common options for this unit. The Winged Sentry allows multiple filter media to be housed inside the filter chamber for applications that emit both particulates and fumes.
