FLEXIBLE DUCTING

RAM Flexible Ducting
There are two types of flexible ducting in the RAM range.

RAM ALUDUCT Low Noise Ducting

This flexible ducting is a three-layer multi-ply reinforced aluminium and polester laminated ducting with an encapsulated high tensile steel wire helix. This means it holds its shape very well offering less drag than competitor products, thus less noise when in use and less pressure drop.
It is individually boxed in 5m or 10m lengths.
It has also been tested for fire resistance and in the event of a fire, no toxic gases are emitted.
