This hood captures unwanted fumes from work spaces

Air Science USA

Air Science USA

The Purair Advanced P20 Ductless Fume Hood (photo) is designed to protect workplace operators from hazardous substances. It provides a face velocity of 100 ft/min to contain fumes. The unit is 49-in. wide, by 27.5-in. deep, by 47.5-in. high. Other sizes are available up to 96 in. wide. The primary filter can be chosen from 14 different types of carbon, including specialty media that is designed to remove vapors of organic compounds, solvents, acids, mercury and formaldehyde. HEPA filters for the removal of particulate solids are also available, to suit specific application needs. The Purair can also be equipped with a secondary backup filter to meet ANSI Z9.5 section 4.12 4.2 requirements. An alarm alerts operators when the airflow falls to an unacceptable level. Switches and electrical components are isolated from the contaminated airflow. The work area has a removable, cleanable spillage tray. Optional integral lighting is available. — Air Science USA, Fort Meyers, Fla.
