Swing Ventilation System

The rocking air system is one of the oldest systems still in use. The principle of the swing system is that the air vents, as with the rail air system, are not above the truss, but in the middle of a compartment. The air vents are opened by means of cam pushers, window pushers and a pull / push tube mounted on the pushers which makes a swinging movement when opening or closing. With this system, some tolerance when glazing is allowed, because the draw / push tube compensates for possible alignment differences of the air vents.
