Air flow control
The Fresh-r saves 35% (avg.) on the overall
ventilation energy by only ventilating when needed.
The air flow rate is automatically adjusted to keep
air quality good. CO
and RH sensors with its smart
2
control are always included in the Fresh-r and are
situated in the outgoing air stream. The automatic
mode can manually be overruled by increasing /
decreasing fan speed. The user interface indicates
the air quality level in 3 steps with icons for good,
medium and bad.
Air balance control
Two backward curved fans are continuously
balanced. This worldwide patented system enables
very direct balance control, also with strong winds.
