The FabricAir^® VarioDuct^™ features an internal membrane to separate the two airflows for heating and/or cooling purposes. This membrane is kept in place by the static pressure and thus does not flutter, providing the perfect airflow for each purpose – heating or cooling.

The connection between damper and membrane is one zipper away–fast and easy! The membrane solution is available for any length of round duct including horizontal bends and concentric transitions. The color of the damper can be matched to the fabric.

The damper is operated manually or automatically with a motorized actuator, allowing the membrane to switch positions. The damper can be controlled using a simple room sensor or via the building’s BMS system.
