Vitalair Downflow Booths
Hosokawa Vitalair's downflow recirculation booths have a direct application in the pharmaceutical, fine chemical and food industries. The air recirculation system ensures complete safety for operators during weighing, drum filling, material transfer, and while operating small lab scale equipment. Air flows downward through a stretched polyester membrane in the ceiling, pushing any dust or vapors away from the operator's breathing zone. The air is extracted from the booth via low level grills mounted in the rear wall. The exhaust air is taken through an EU4 primary filter, an EU8 second stage fine dust filter and then finally through a third stage EU13 HEPA filter before recirculation into the booth. Designed with flush fitting panels and no contamination prone crevices, our booths are constructed from satin polished stainless steel or white powder-coated zintec steel and are available in standard safe working depths of 1.3m - 2m. The length and height of the booth can be customized with widths ranging from 1.5m - 12.0m and internal heights ranging from 2.0 - 9.0m. We can supply our downflow recirculation booths as a stand alone "plug in" requiring a 3-phase electrical supply or as a fully integrated system designed to fit into an existing system.

The unique air flow patterns inherent in the downflow design illustrate the degree of protection to the operator, with all air flow and entrained particulate away from the operator.

Typical applications include:
  • Product dispensing
  • Raw material transfer
  • Finished goods sampling
  • Weighing and mixing
  • CIP work areas
  • High containment work zones
  • Operating small lab scale equipment
These Down Flow Booth have also been supplied with the following options:
  • Benches and weigh scales
  • Localized dust extraction hoods within the booth
  • PC terminals for batch data recording
  • Lifting devices
  • Roller conveyors
  • Roll down doors
