This dual 140mm PC fan duct adapter combines two standard 140mm fans into one flexible exhaust hose. Outlet sizes are available in 3, 4 and 5 inch for PC exhaust, server ventilation, sim racing wind systems and other custom airflow projects.
The standard version is made in PETG with an 80°C (176°F) heat tolerance, selected for better heat resistance than PLA in warm PC, radiator and ventilation environments. For installations that may run hotter, a higher-temperature material option is available on request for most sizes; contact us before ordering to confirm suitability.
Reducing two fan outlets into one hose increases system resistance, especially with smaller duct sizes, long hose runs or multiple bends. Fan choice and duct layout will affect final airflow.
