The Helios DIF 315 is an aerodynamically designed diffuser engineered to maximize pressure recovery in ventilation systems. By introducing a size transition, it slows the airflow, converting dynamic pressure into static pressure for improved efficiency. It can also function as an adapter to facilitate a smooth transition to a larger duct size.
This diffuser is particularly suitable for installation directly after a fan or at the end of a duct system where it serves as an outdoor outlet with reduced discharge losses. If the diffuser is used as a free outlet, a protective grille (type SG) in the next larger size is recommended for added safety.
Made from hot-dip galvanized steel, the DIF 315 features a high-quality build with a double-sided welded flange and a standardized hole pattern according to DIN 24155.
