Weighing Booth Extractor
Weighing Booth Extractor is designed specifically for powder containment
applications, the Powder weighing enclosure employs carefully directed inward airflow
at the face of the enclosure to hazardous powders or potent pharmaceutical compounds.
The aerodynamically designed enclosure reduces airflow turbulence for maximum containment
while minimizing the effect that air drafts may have on sensitive weighing balances.
The enclosure design exceeds the containment requirements of proven by independent
type testing. All exhaust air is HEPA-filtered, removing virtually all particulate
matter, before recirculation to the laboratory.
weighing booth extractor Unitis with a variety of standard dimensions
also our cabinet can be custom engineered to any size. Weighing Booth Extractor
available in powder coated Mild Steel, SS 304 / 316 / 316L or a
combination of both.
