A controllable slot ventilator comprises first and second parallel side walls (28,30) which define an air passage (32) between them. A closure member (34) is mounted adjacent the front edges of the side walls via parallel motion links, which allow then closure member to move generally away from and towards the side walls to open and close the ventilator. At the rear of the side walls, i.e. the opposite end to the closure member, a mounting flange (38) is fitted, whereby the ventilator is mounted to a member. When the ventilator is installed in a slot, it is preassembled and then inserted into the slot from one end. (Figure 1A)
