Ductless fume hoods provide maximum operator protection

Air Science USA’s advanced ductless fume hoods series offers sophisticated airflow, filter alarms and advanced safety features. The units are available from 2–8ft.

The Fort Myers, Florida-based firm says they 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 totally isolated from the dirty airflow and away from any contamination.

The work area has a removable spillage tray, which is easy to clean. Optional integral lighting is available.

The main filter can be chosen from 14 different types of carbon, including specialist media for vapours of organics, solvents, acids, mercury and formaldehyde.

HEPA filters for particulate filtration are also available to suit application needs.

Air Science says the units save energy as clean air is recirculated into the laboratory therefore they do not exhaust expensive conditioned and/or heated air into the atmosphere.
