The Winged Sentry with Lid is a compact benchtop fume extractor which offers a unique and customized design that includes adjustable “wing flaps” and a clear acrylic hinged lid to assist in directing fumes into the unit’s inlet and filter chamber. These wings are adjustable according to the operator’s preference and the hinged lid provides a hood-like enclosure for added containment.

Appropriate filtration media is installed in 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 media [i.e. Acid Gas, Mercury, Aldehyde, Ammonia] are the most common filters for this unit. The Winged Sentry is an optimal choice for fume extraction in applications such as soldering, capsule filling, powder filling, solvent and epoxy fumes, R&D, light grinding and a variety of applications involving chemical fumes and dusts.

The Winged Sentry with Lid provides a highly energy-efficient, quiet and economical solution to many fume extraction needs.

The Winged Sentry is also available without a lid [SS-200-WS] and also with a more powerful fan [SS-300-WSL].
