Air Science USA has introduced a range of ductless fume hoods with sophisticated airflow, filter alarms and advanced safety features.
These units are available from 2ft to 8ft.
These fume hoods have been designed to provide maximum operator protection when using hazardous substances.
A face velocity at 100fpm 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 isolated from the dirty airflow and away from any contamination.
The work area has a removable spillage tray that can be easily cleaned.
Optional integral lighting is available.
The main filter can be chosen from 14 different types of carbon, which include specialty media for vapours of organics, solvents, acids, mercury and formaldehyde.
HEPA filters for particulate filtration are also available to suit application needs.
The units are also said to be energy saving.
Clean air is recirculated into the laboratory, therefore, the hoods do not exhaust expensive conditioned and/or heated air into the atmosphere.
