ABSTRACT:
A device for altering the airflow pattern from a ceiling vent diffuser. The device comprises a flexible member that is secured to a diffuser vane by a spring-biased hook and one or more tabs. A release button on the outer surface of the device is depressed to pivot the hook out of engagement with the vane. The device is complementary shaped to a region of the diffuser. When installed, the device blocks the openings in that region and substantially prevents air from flowing out of the openings. One or more devices may be installed in selected regions to block airflow from those selected regions. A plurality of devices may be utilized to completely prevent airflow from the diffuser.
