Our most popular range with sophisticated airflow and filter alarms and advanced safety features. Available in sizes from 2.5 to 6 feet.

Introduction
The Purair range of ductless fume hoods have been designed to provide operator protection when using hazardous substances.

A face velocity at 100 fpm ensures containment of fumes and an alarm will alert the operator when the airflow falls to an unacceptable level.

All mechanisms in the head section of the Purair are on the clean side of the filter, thus preventing contamination.

Switches and electrical components are totally isolated from the dirty airflow and away from any contamination.

The work area has a removable spillage tray which can be easily cleaned. Optional integral lighting is available.

Filter Selection
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. In addition, the Purair can be equipped with a secondary back-up filter for added protection. This filter is required by US standard ANSI Z9.5 section 4.12 4.2.

Typical Applications
Typical applications include weighing, chemical sampling, histology, forensic and pharmaceutical

Efficient and Economical
These units are energy saving. Clean air is recirculated into the laboratory, therefore, they do not exhaust expensive conditioned and/or heated air into the atmosphere.
