Helios Fans DIF 500
Helios
Prices & Options
The Helios DIF 500 diffuser is designed to enhance ventilation system performance through aerodynamic optimization that enables high pressure recovery. By introducing a step-up in size, it slows down the airflow, converting dynamic pressure into static pressure efficiently. It also doubles as an adapter for seamless transitions to larger duct sizes.
This model is ideal for installation immediately after a fan or at the end of a duct run, serving as an outdoor discharge point with minimized outlet losses. When used as a free outlet, a protection grille (type SG) in the next larger size can be added for additional safety.
Constructed from hot-dip galvanized steel sheet, the DIF 500 is built for durability and includes a double-sided welded flange. The hole pattern follows DIN 24155 specifications, ensuring compatibility with standard fittings.
