RAM Aluduct Ducting – 4" to 12" Low-Noise Aluminium (5m & 10m)

Ducting is the one part of a ventilation system nobody admires, which is exactly why it's so often the part that lets everything down. A great fan pushing through crumpled, saggy, rattling ducting is a great fan wasted. RAM Aluduct is the fix: three-ply aluminium and polyester laminate wrapped round a high-tensile steel wire helix, so it holds a smooth round bore instead of collapsing into a noisy concertina. Why Aluduct Holds its shape. The encapsulated steel helix keeps the duct round. A smooth bore means less drag, more airflow and less noise than flimsy foil ducting. Tough 3-ply laminate of aluminium and polyester, which resists tears and pinholes far better than single-layer foil. Light and easy to work with. It cuts to length with a sharp knife and wire snips, and bends round corners without kinking. The best value way to move air. The cheapest RAM ducting per metre, ideal for straightforward runs. Sizes Every diameter comes in 5m and 10m lengths: 4" (102mm), 5" (127mm), 6" (152mm), 8" (203mm), 10" (254mm) and 12" (315mm). Match the ducting to your fan and filter.

Never leave a 10m duct crumpled up in a 2m run. Bunched ducting roars, traps condensation and robs your fan of a big slice of its airflow. Keep runs short and straight, use smooth gentle bends, and finish every joint with a clip and a wrap of aluminium tape." FAQ How do I cut it? Slice the laminate with a sharp knife, then snip the steel wire with side cutters. Fold the cut wire end inwards so it doesn't snag. How do I attach it? Slide it over the fan or filter spigot and secure it with a ducting clip or jubilee clip, then tape the joint. Is it the same diameter as my fan? Use the same size as your fan's spigot, e.g. a 6" fan takes 6" (152mm) ducting.
