GRAVITY SHUTTLE

It is one of the possible elements of the outlet end point of the ventilation system, the operation of which is ensured by the air movement created by the air flow generating unit (e.g. fan, hood, etc.) located in the system. When the unit placed in the system is operating, the formwork is in an open state, and then closes after it stops. It protects the system from external influences, as well as from possible reverse air flow.
Applicable: Due to its double pipe connection, for ventilation systems with a diameter of 100 mm and a diameter of 120 mm and a circular cross-section. When connecting to a system with NA=120 mm, the 100 mm connector must be removed! This is possible with pliers for the part that is eased next to the perforation. It cannot be connected directly to the 120mm Gonal ventilation pipe, but the connection can be made by appropriately modifying the segmented pipe connection elements placed on the formwork (with the help of pliers).
