Abstract

In a method for providing substantially constant air flow velocity through the door opening of a fume cupboard for laboratory applications and the like, independent of the size of the cupboard door opening, this cupboard door opening is sensed first, whereon the exhaust air flow from the cupboard is continuously controlled in response to the sensed door opening. In an apparatus for providing such substantially constant air flow velocity a measuring device (18, 20, 26) is disposed for delivering a signal varying continuously with the opening of the door (12), said signal controlling a regulator (34, 36) in the exhaust air duct (14) from the fume cupboard (10).
