DKL - Circular nozzle duct
Even air distribution over long distances at variable airflow rates
Repus DKL nozzle ducts can be installed freely suspended in the room, with a mixing air distribution to both sides. This innovative Swedish invention revolutionises ventilation solutions by combining energy efficiency with exceptional performance. The system offers a variable airflow rate, enabling smart sizing for maximum conditions, followed by intelligent adjustment via a damper, CO₂ measurement and temperature measurement in smart building systems.
With its low pressure drop and minimal energy consumption, the DKL series represents the future of sustainable ventilation. The longitudinally seamed construction in sizes from 160 mm to 630 mm is manufactured in galvanised sheet steel with a powder-coated finish in RAL 9003, gloss 30%, ensuring both aesthetics and long-term performance without sensitive materials.
