Performance Features

With electronic duct dampers, an appliance module and any X10 timer, you can reduce your heating/cooling expenses by cutting off airflow to unoccupied rooms during work hours. Or, if you want a room to be a little colder or warmer than the rest of the rooms in the house (i.e. grandma and grandpa's bedroom), any mechanical thermostat can close the damper when a pre-specified temperature is reached.

These 24V Motorized Dampers are available for 6", 8", 10" and 12" duct diameters, and can be ordered in normally-open or normally-closed configurations. When no power is supplied to the Normally Closed unit, the damper will be closed. When no power is supplied to the Normally Open unit, the damper will be open.
