ABSTRACT:
A modular automatic power flow fresh air inlet comprising a housing having fresh air openings between a source of fresh air and a room, having an adjustable static pressure to be ventilated. The fresh air openings may be controlled by a valve plate pivotally connected to the housing at each opening. The valve plates pivot relative to the static pressure in the room. A cable having first and second ends extends through the housing and is connected to the valve plates via a lanyard. A cable control device for moving the cable between a forward position and a rearward position is connected to the first end of the cable. A cable counter weight is attached to the second end of the cable. Moving the cable toward the forward position places tension on the lanyard, causing the valve plate to pivot from the static position toward to the fully opened position. Moving the cable toward the rearward position relaxes the tension in the lanyard, causing the valve plate to pivot toward the static position. A plurality of fresh air inlets may thereby be connected in series via the cable for regulating an air flow course within a building.
