An air flow apparatus for providing a continuous curtain of air or other fluid includes a body member defining a first elongate plenum chamber, at least one inlet opening through which the first plenum chamber receives compressed air and an outlet opening for discharging air from the body member. The apparatus may also include a second plenum chamber (which communicates with the outlet opening) and at least one passageway connecting the first and second plenum chambers. The body member discharges the air without deflecting it towards one of its outer surfaces.
