DELTA-AD is an exhaust air cowl with a modern design for use in comfort and industrial facilities. DELTA-AD is de-signed for a low pressure drop in combination with documented good water separation. DELTA-AD has a design that allows the exhaust air to rise straight up at increased speed. Supplied as standard with integrated lifting points to facilitate installation. DELTA-AD is ideally installed on our roof inlet BRTG as it passes through the roof. Eyebolts can be supplied if necessary (state in plain text when ordering).
