Clean Hood

A fume hood for laboratory tables and the like is well known and is conventionally employed to exhaust unwanted gases from work areas. Many different configurations have been employed in the past.

However, the present apparatus is designed to provide a ventilating method and apparatus effective to maintain a uniform, air intake without dead air spaces and with minimum floor space. This is accomplished in a hood by providing an air flow that is horizontally laminar, with the flow entering on the left side of the hood and exiting on the right side of the hood, thus eliminating the detrimental aspects of vertical flow through the hood, and subsequent adverse effects, such as the elimination of dead airspace, are avoided. The hood is self-contained, recirculating its own air, resulting in superior air cleanness. If the hood encapsulates an automated work station, it can be fully enclosed, resulting in an ability to closely control atmospheric humidity, temperature, and the type (inert gas) of atmosphere.
