Abstract

The present invention provides one or more autonomous in-duct or register grill mounted flow control devices, each of which has the capability to restrict or boost air flow through the duct or vent to which it is attached. The individual flow control devices may be in communication with other flow control devices in the duct works, having an ability to adapt in a cooperative fashion to optimize the environment served by the ductwork. In a preferred embodiment, each of the flow control devices provides its own power and does not require changing the existing ductwork or register boxes for installation.
