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.
