Ram PVC Combi Ducting – 5″ x 10m

The lightproof flexible ducting from RAM is a four-layer multi-laminated construction with an encapsulated high tensile steel wire helix which ensures strength and durability. The black PVC outer is plant safe and is a strong vapour/light barrier which ensures extra air tightness over a standard alloy ducting while remaining very flexible.
Due to the four-layer structure, this ducting holds its shape with a seamless void when fully extended, delivering low pressure drop, no particulate clogging and little noise when in use.
It is available in 10m lengths and has been test for fire resistance.
