Abstract
The moving parts of a hatch device (6) used to alter the size of an access opening (10) for a ventilated work region are continuously controlled with the aid of a recording region defined in the opening. An air extraction device (7) coupled to the ventilated apparatus is also continuously controlled according to the positions of the moving parts. Controlling and regulating a flow of air through an apparatus (1) for ventilation is carried out in a apparatus comprising a ventilated work region, a hatch device providing access to this region, and control and regulating devices. The moving parts of the hatch device used to alter the size of the opening through which a hand or arm has to be placed in order to access the work region are continuously controlled and regulated with the aid of a recording region defined in the opening. An air extraction device coupled to the apparatus is also continuously controlled and regulated according to the positions of these moving parts. An Independent claim is also included for the apparatus in which the above method is carried out.
