Benefit with OpenAir

A portfolio for all your needs

Energy-efficient, simple to use, and reliable: Ease of use is at the heart of the entire damper actuator portfolio, from smooth installation and rapid commissioning to operation that is both efficient and convenient. You can save time and costs by using the standardized wiring plan, and self-centering shaft adapters. Simply choose from four housing sizes that were built for even the most challenging HVAC applications.

OpenAir damper actuators are easily tailored to your requirements. Siemens offers durable damper actuators for any application: comfort ventilation, variable air volume, fire and smoke protection dampers, railway vehicles and other special applications. You have the choice between a large selection of positioning forces, communication busses and control signals. Siemens extensively tests all damper actuators and provides an incredibly robust housing which enables lifecycles of more than 100'000 full and 5 million partial cycles. Installation is made simple and error free thanks to prewired actuators, color- and number-coded cables, a uniform unit mounting concept, as well as single-screw shaft mounting. Finally, energy consumption and comfort are dramatically improved thanks to efficient high-precision motors, low-noise brushless motors, and the rapid implementation of commands from the building automation systems.
