CONTROLLABLEPITCH
forVariableAirVolumeSystems
Sensors compensate for changes in temperature, humidity,
air flow, gasconcentrationor air qualitybyaltering theblade
pitch to increaseor decreaseair volumeor pressure.Fan is
ideal forVAV systems and for industrial applications requir-
ing a constant environment regardless of air demand.
