The HELI GX225 window fan from Helios is a powerful ventilation fan designed for installation in windows and walls. With an air flow rate of up to 725 m³/h, it ensures effective air circulation indoors. The fan is reversible, meaning it can be used for both supply and exhaust air. The housing is made of impact-resistant plastic and features an electrically operated internal shutter that guarantees reliable sealing. An external rain guard grid protects against incoming water and ensures long-lasting use. The HELI GX225 is equipped with a maintenance-free, infinitely variable AC capacitor motor that has a closed design and operates with long-life lubricated ball bearings. These features make the fan an ideal solution for efficient and flexible ventilation.
