Flex Ducts

Aluminium flexible ducting in 100mm, 125mm and 150mm diameters, supplied in 6 metre lengths — the standard run for connecting bathroom and laundry exhaust fans through to an external vent or roof cowl.

Match the duct diameter to the fan spigot rather than the vent: stepping down chokes airflow and is the usual reason a fan sounds like it is working but the mirror still fogs. Keep runs as short and as straight as practical, and support the duct so it cannot sag into a water trap. Pick up from the North Parramatta trade counter or have it sent out — Mon–Fri 6:30am–5pm, Sat 7:30am–1pm.
