Abstract

An air flow controller has an adjustable air flow passageway and comprises a surface-mounted distribution frame housing one or more elongate passages. Each passage has an inlet, a flow channel and an outlet. The inlet has two opposed guide flaps to control the flow of air passing into the flow channel. Two opposed wall members define the width of the channel, the wall members being adapted to be position-adjusted on control movement of the guide flaps with the outer ends of the wall members defining the outlet.
