Air Science USA has introduced a new range of ductless fume hoods available in sizes from 2 to 8 feet.
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, preventing contamination. Switches and electrical components are isolated from the dirty airflow and away from any contamination.
The work area has a removable spillage tray, which can be easily cleaned. The filter is available in 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.
These units are energy saving. Clean air is recirculated into the laboratory; therefore, they do not exhaust conditioned and/or heated air into the atmosphere.
