High-performance exhaust for healthy barn climate
The Exhaust Air Duct, a UV-resistant polyethylene chimney system, is built to transport stale, warm barn air out efficiently – without moisture or energy loss. With tight insulation (0.022 W/mK) and smooth internal surfaces, it avoids condensation even under changing conditions
With a full product range including diffuser, intake nozzle (boost airflow by up to 15%), shutter module, optional silencer and light trap, the Exhaust Air Duct supports a fully integrated exhaust system inside the chimney itself.
The Exhaust Air Duct advantage
Wide airflow capacity & flexible sizing
Handling from 5,000 to 52,000 m³/h, the Exhaust Air Duct is available in diameters from 370 to 1,270 mm and fits a variety of fan modules, making it adaptable to different ventilation system requirements.
Insulated & condensation-resistant
A rigid PU foam “sandwich” design with GRP-coated interior and exterior prevents condensation and thermal bridging, protecting barn structures and maintaining a stable indoor climate.
Fast, quiet installation
A tool-free “click” system ensures compact shipping, rapid setup, and improved hygiene. Optional silencers cut exhaust noise by up to 12 dB(A), enhancing comfort for animals and nearby residents.
