Copra Hybrid represents a new generation of centrifugal fan technology, built around an integrated spiral-shaped multi-part guide vane system. This dynamic aerodynamic optimization enables system efficiencies of up to 80%, redefining performance standards for plug fan solutions. The hybrid concept combines the easy handling and installation flexibility of free-running centrifugal fans with the aerodynamic effectiveness of traditional housing fans. The directly driven centrifugal impeller works in perfect interaction with the motor and multiple discharge spirals to minimize turbulence and maximize energy performance. Designed for practical integration, Copra Hybrid allows floor, wall, or ceiling installation. Its accessible construction simplifies maintenance and cleaning, making it ideal for high-performance air handling systems requiring both efficiency and serviceability.
