The Purair Advanced P20 Ductless Fume Hood from Air Science provides operator protection when using hazardous substances. A face velocity at 100 fpm ensures containment of fumes, according to the company, and an alarm alerts the operator when the airflow falls to an unacceptable level.
All mechanisms in the head section of the Purair Advanced P20 are on the clean side of the filter, 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.
The Purair Advanced P20 is 49" wide by 27.5" deep by 47.5" high. Other sizes are available up to 96" wide. The main filter is available in 14 different types of carbon, including specialty media for vapors of organics, solvents, acids, mercury and formaldehyde. HEPA filters for particulate filtration are also available. The Purair can be equipped with a secondary backup filter for added protection. The filter is required by U.S. standard ANSI Z9.5 section 4.12 4.2.
