Combination cowl DELTA-KD is a combined intake air and exhaust air cowl for use in comfort and industrial facilities. The intake air and exhaust air sections are separated inside the cowl by a partition wall. The exhaust air side is designed for a low pressure drop in combination with very good water separation. In order to prevent the transfer of exhaust air to the intake air, the combination cowl has a design that allows the exhaust air to rise straight up at increased speed. The intake air is taken in on the lower edge of the outdoor air section. The intake opening is covered with an insect-proof wire mesh. DELTA-KD is supplied as standard with integrated lifting points to facilitate installation. DELTA-KD is ideally installed on our roof inlet BRTF when it passes through the roof. Eyebolts can be supplied if necessary (state in plain text when ordering)
