ABSTRACT:
A slot ventilator including a housing and a closure member. The housing includes a face with an airflow opening defined in said face. When the closure member is in a first position, the closure member abuts against the face and generally closes the airflow opening. When the closure member is in a second position, the closure member is offset from the face and the airflow opening is generally unobstructed by the closure member. The housing further provides a drive mechanism for displacing the closure member from the housing.
