Abstract
A low-power, wireless, inflatable bladder damper device for controlling the flow of air through an airflow channel, and a method of operation for the same. Rather than requiring power supply and/or control wiring for operation of a wireless damper device, a low-power inflatable bladder damper device that requires no external wiring for operation can be used. A completely wireless damper device can reduce the cost of installation of damping devices in airflow channels, as well as the complexity of installation, while at the same time providing improved control of airflow throughout an airflow system.
