These hoods are suitable for providing personal protection needed for general chemistry applications involving fumes and vapors. They meet the SEFA-1 standard of a low velocity, high performance hood and may be safely operated as low as 60 fpm. Choose from hoods designed to be used with a remotely-located blower or hoods that include a built-in blower — the only high performance hood with built-in blower available anywhere. Explosion-proof hoods with built-in blower are available for laboratories with potentially explosive/flammable atmospheres (Class 1 Div I or II).
