Superior actuators for air volume control
Reduced outlay, increased comfort: That
neatly summarizes the solid benefits the
OpenAir VAV controllers offer. It’s all made
possible thanks to maximum precision,
excellent stability and winning flexibility –
including the ability to respond rapidly
to changed requirements.
Practical installation, varied application
Fast and simple adjustment to VAV boxes
makes complicated and time-consuming
installation a thing of the past. And because
all common communications standards are
accommodated and the VAV modular con-
troller turns every 3-position actuator into
a VAV actuator, you get to enjoy a much
greater range of application than ever before.

more possibilities, more convenience
