Prices & Options
The Helios HDH 400 is a horizontal roof ventilation cowl designed to cover convection outlets and supply air openings on rooftops. Built in the same style as the RD series roof fans, it provides a consistent aesthetic and functional solution for roof installations. When used in mechanical ventilation systems, any resulting airflow losses should be considered during system planning, as detailed in the performance diagrams.
