Abstract
An airflow test device designed to be used in a clothes dryer. The device includes a retainer which is mounted to an outlet grate of the dryer drum. A vent card is removably supported a predetermined distance from the outlet grate by a support finger extending from the retainer. The vent card is supported in such a manner that a predetermined rate of airflow through the outlet grate during dryer operation moves the vent card toward the outlet grate. Movement of the vent card toward the outlet grate and off the support finger during clothes dryer operation signals that an adequate rate of airflow is passing through the outlet grate.
