Chain Drive KS4 24 V S12

No other chain drive develops more power in such little space as the KS4 from AUMÜLLER. It sets the mark with ist advanced connectivity, independently integrates itself in a multi-drive system by means of M-COM-Click and communicates confidently with modern building management systems.

Surface mounted or in profile integration? Frame or casement profile? It doesn’t matter how and where you install the KS4: the assembly is easy and the chain drive performs discreetly.

Unique connector solution: double-sided plug-in connection makes it possible for a series connection of up to three drives and one locking drive. The best: the configuration in multi-drive systems is self-taught. This means more flexibility for you – and less effort.

Uncompromisingly high-quality, uncompromisingly reliable: KS4 achieves permanent, optimal results for your natural ventilation. The visually appealing and robust aluminium housing protects the electronics, motor, gear and chain box. This guarantees unrivalled durability – Made in Germany.
