Helios RR EC 315 B

The Helios RR EC 315 B is a powerful EC radial duct fan designed for direct installation in duct systems. With a housing made of galvanized steel and round connection flanges compatible with standard ducts, this fan offers a robust and durable solution for ventilation technology. The radially arranged impeller with backward-curved blades ensures a high air flow rate of up to 2031 m³/h and high efficiency. The energy-saving EC external rotor motor is speed controllable and has an IP 44 protection rating, making it ideal for use in various environments. Additionally, the fan is maintenance-free and interference-free, minimizing operating costs and increasing reliability. The integrated electronic temperature monitoring provides additional safety and efficiency. Connection is made via a standard terminal box, allowing for easy installation.
