Vitalair Downflow Booths

Description

Achieving a minimum 99.99% filtration performance, Hosokawa downflow recirculation booths are used particularly where hazardous, toxic or sensitizing powders are handled, typically in pharmaceutical, fine chemical and food industries.

Internally constructed in satin polished stainless steel or white powder-coated zintec steel, the Vitalair booths are available in a range of standard sizes from 2m to 4m wide and with a safe working depth of between 1.3m and 1.8m.

Hosokawa are able to supply downflow recirculation booths as a stand alone "plug in" facility requiring only a 3 phase electrical supply or as a fully integrated system purpose-designed into an existing facility.

The air recirculation system ensures complete safety for personnel as a conditioned downflow of air passes vertically from the booth's ceiling inlet plenum pushing any dust or vapours downwards and 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 volume is taken through an EU4 primary filter, an EU8 2nd stage fine dust filter and finally a 3rd stage EU31 HEPA filter prior to recirculation into the booth.

Designed with flush fitting panels and with no contamination prone crevices all our downflow booths are also available in non-standard sizes and layouts to suit customer requirements. Non-standard sizes have been supplied between 1.5m and 12.0m wide and from 2.0m to 9.0m high internally.
