Designed by Dowse Engineering for ducted exhaust and extraction applications. The Cyclo Vertical range of exhaust fans use axial flow and centrifugal design to provide high pressure characteristic stable over a wide range of airflow. The design allows for lower RPM and subsequent lower energy and noise levels.
