Air Science Introduces Ductless Fume Hood

The Purair 5 ductless fume hoods from Air Science USA feature operator protection where routine work is being carried out. The ductless design eliminates installation costs and allows the unit to be positioned over a sink or benchtop apparatus.

The units operate at low noise levels and because they recirculate, they do not exhaust 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 to prevent bypass leakage.
