The solution is available as a set, consisting of a KS4 400 chain drive and a filigree casement bracket with an integrated preloaded spring.
This spring preload ensures the stability of the window - whether in open position or during opening and closing. This makes bended chains a thing of the past and you achieve permanent stability in any condition.
You require an even higher locking force in a closed position? No problem - the system can be combined with any AUMÜLLER locking drive.
The side-hung window can be opened by the drive up to 70 degrees in 45 seconds. This large opening angle ensures the best ventilation and smoke exhaust cross-sections. This makes the "DrehVolution" ideally suited for us in ventilation and smoke and heat ventilation systems.
The new system not only impresses with its time-saving and simple installation, but also with its attractive appearance. The space-saving installation - only 26 mm on the frame is requireed - ensures that the modular system can be integrated discreetly into the room layout.
