OpenAir damper actuators –move a lot with little energy

Durable, robust actuators for HVAC applications, air volume controlas well as fire and smoke protection dampers

Damper actuators forefficiency at every stage

OpenAir™ damper actuators are used in millions of applications worldwide.Thanks to their rugged, compact design, they’re not only easy to install but also extremely durable in operation, during transport and on the construction site. The low-consumption motors deliver high positioning forces using little energy. High precision provides a pleasant, controlled room climate and ensures optimal energy efficiency, which helps to reduce operating costs.You receive expert assistance in every project phase, including tools such as the HIT Portal for simple, time-saving selection and planning of all field devices, or data matrix codes for immediate access to all product information.

Maximum satisfaction at minimum cost

A product range to cover every need

With their standardized dimensions and cabling and installation concept, OpenAir damper actuators are designed for direct coupling and fast commissioning. With all series, the actuators are fixed to the damper shaft with a single screw. In addition, self-centering shaft adapters reduce installation work, which saves you time and costs.
The choice of four sizes of housing covers all HVAC applications, from recirculated air dampers, outside air dampers and shutoff dampers, to variable air volume control and fire protection dampers to central air handling units. And demanding applications with special requirements, such as fume hoods in laboratories, are no problem either. The product range also includes VAV1) compact controllers with all important communication standards.

Convenience in every area

But the OpenAir product range is not only convenient for installation and commissioning. Thanks to their fast and precise implementation of instructions from the building automation system, the damper actuators help to provide a constant room climate.

In addition, their brushless motors, gear trains that have already been run in and precisely mounted technology ensure especially quiet operation. This is ideal for areas where intensive work is carried out, as well as for night-time operation such as in hotels and hospitals. 

Best quality based on many years of experience

OpenAir™ damper actuators are based on solid application expertise and Siemens’ decades of experience in manufacturing actuators. They are tested intensively in
the in-house HVAC lab, thus ensuring stable control loops and offering a level of reliability that you can count on.

Full support for practical application

Siemens supports you with its full expertise and provides practice-oriented support, for example with tools to facilitate your daily work as well as with its global service network.

Highlights

■ Energy and cost savings thanks to low-consumption motors and high accuracy
■ High level of investment protection through long service life and maximum reliability
■ Fast, simple installation and commissioning
■ Optimum comfort for living and working environments thanks to proven technology
■ Professional support and practice-oriented tools

Actuators for HVAC applications

Powerful safety

OpenAir actuators for HVAC applications are available for low and high torques ranging from 2 Nm to 35 Nm and 125 N to 550 N respectively, so you can choose the right product for any type of application. 

The powerful actuators with 35 Nm offer maximum safety under demanding operating conditions. And with their compact design, the small actuators with 2 Nm are
ideally suited for difficult installation conditions. They can also be easily mounted in tight places, e.g. in false floors. Fastrunning damper actuators with a torque of 6 Nm, 2 s running time and a long service life are perfectly suited for special applications like fume hoods.

Simple and safe installation

Self-centering shaft adapters simplify installation and reduce installation expenses – and make mounting foolproof. They can be installed from both sides, enabling them to be fixed on short shafts without difficulty. They also reduce the stress on the actuator, which increases its service life and reliability.

Highlights

■ High reliability thanks to high torque
■ Compact actuators for difficult installation conditions
■ The suitable actuator for every application – e.g. fastrunning damper actuators for laboratories
■ Simple installation thanks to self-centering shaft adapters
