Fast, with precision metering for optimum uniformity.


VAV product broschure 

Simple installation and maintenance

The user-friendly design of the 327 VAV actuators enables you to complete adjustment on the construction site in a very short time, then the actuator is ready for operation. A good VAV actuator also needs to be easy and safe to install. We make sure of this by providing suitable flanges and shaped connector inserts.


Precision control of air flows: VAV solutions from Gruner

Regardless of whether you need accurate metering for the control of airflows in residential properties, for comfort at the workplace or for process air, you are defining challenging requirements for the actuators you need to do the job.

Would you like to learn right now about our portfolio of appropriate actuators? Here you will find details of our complete product range:


Precise control

A good VAV actuator enables you to control the volumetric air flow precisely. It should be capable of adapting the air flow precisely and reliably to satisfy the requirements.

Good linearity

The VAV actuator should exhibit good linearity across a broad area of the control range. This means that the volumetric flow rate is proportional to the position of the actuator. Linear control makes it possible to control the airflow precisely and to adapt it to meet requirements.

Great reliability

A good VAV actuator needs to be dependable and durable. It should deliver consistent performance across an extended period and needs to be able to cope with the requirements of the ventilation system.

Integration in control systems

Whether analogue or digital, a VAV actuator must fit in with your technical control concept. This is the only way for it to be sufficiently universal, meaning that it can be used anywhere.

This is what our VAV actuators can do

Linear regulation

No surprises, no irregularities: with Gruner VAV actuators, linear regulation of volumetric flow rates is no problem at all. Thanks to a balanced design of components to match the uniform actuation of air vents, consistent adjustment of volumetric air flow is a highly dependable and reproducible operation.

Excellent service life

Because of their rugged design and their compliance with current standards, our VAV actuators are also ready to satisfy future requirements. Also, their electromechanical design rating, suitable for more than 100,000 movement cycles, makes them reliable components for the future of your HVAC system.

Quick to install, zero maintenance

By virtue of their clear connection elements, their compliance with commonly applied standards for power supply and control as well as their use of all relevant protocols at component control level, our actuators can be integrated very easily into virtually any system.
