The SPR-CU series elevates standard ventilation to a new level by combining the high-performance engineering of SPR spiral ducting with the unique properties of pure copper. These ducts are the ultimate choice for projects that demand not only exceptional performance but also superior hygiene and a distinguished aesthetic. The natural antimicrobial properties of copper make it an ideal material for environments where air quality and the suppression of microbial growth are critical.
Engineered with the same precision as the entire SPR line, all copper ducts meet the highest standard of Class D air tightness, ensuring that their functional performance is as impressive as their appearance.
Key Features & Benefits for Architects, Engineers, and Building Owners
Natural Antimicrobial Properties: Copper is scientifically proven to be inherently antimicrobial, effectively suppressing the growth of bacteria, fungi, and molds on its surface. This provides an added layer of protection for air quality in sensitive environments.
Unmatched Aesthetic Appeal: The warm, rich finish of copper provides a striking visual element, making SPR-CU ducts a perfect choice for architecturally significant spaces with exposed ductwork. Over time, it develops a unique and beautiful patina, adding character and distinction.
Exceptional Durability & Longevity: Copper offers outstanding corrosion resistance and durability, ensuring a very long service life. It is an investment in a system that is built to last for decades.
Certified Class D Air Tightness: Guarantees minimal air leakage according to EN 12237 standards. This is essential for maintaining system efficiency, reducing operational costs, and ensuring optimal indoor air quality (IAQ).
Structural Integrity: For enhanced stiffness and resistance to negative pressure, ducts with a diameter of Ø250 mm and greater are reinforced with standard external corrugations, ensuring robust performance even in large-scale systems.
