Ductless Fume Hoods
The new PURAIR 5 Ductless Fume Hoods feature a high level of operator protection where routine histology, powder weighing and sampling prep work is being carried out. The unit can be placed on any bench top, and an optional polypropylene spillage tray can be provided when required. The rear of the unit has lighting to illuminate the work surface. A face velocity of 100 fpm ensures containment of fumes and particulates for operator protection. An alarm alerts the operator when the airflow falls to an unacceptable level. The units operate at low noise levels and because they recirculate, they do not exhaust expensive conditioned and/or heated air into the atmosphere. 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. The units exceed OSHA, ANSI and all relevant international standards.
