The NEW PURAIR 5 Ductless
Fume Hoods from Air Science
USA feature a high level of
operator protection where routine
work is being carried out.
The units exceed OSHA, ANSI and
all relevant international standards.
The Ductless design eliminates
installation costs and allows the unit
to be positioned over a sink or
There are three models available
with a choice of 24", 36" or 48"
The units operate at low noise
levels and because they
recirculate, they do not exhaust
expensive conditioned and/or
heated air into the atmosphere.
A face velocity of 100 fpm ensures containment of fumes and particulates for operator
protection. An alarm alerts the operator when the airflow falls to an unacceptable level.
The unit can be placed on any bench top, and an optional polypropylene spillage tray can
be provided when required. The rear of the unit has lighting to illuminate the work surface.
All mechanisms in the head section are on the clean side of the filter, with the switches
and electrical components being isolated from any contamination.
The patented filter clamping mechanism allows for the filter to be easily installed and
ensures an even seal at the filter face at all times to prevent bypass leakage.
The main filter can be chosen from 14 different types of carbon, which include specialty
media for vapors of organics, solvents, acids, mercury and formaldehyde. HEPA filters for
particulate filtration are also available to suit your application needs.
Typical applications for the Purair 5 include histology, powder weighing and sampling
