Flexible Duct Combi – 127mm x 5m

A 4 layer multi-laminated construction, with an encapsulating high tensile steel wire helix that ensures strength and durability. The black PVC outer is totally plant safe and a strong barrier ensuring extra air tightness over standard alloy ducting while still being very flexible.
Due to the 4 layers (when fully extended), the ducting folds it shape with a seamless void delivering low pressure drop and no particulate clogging and low noise when in use. This ducting has a clear layer on the inside and a black lightproof layer on the outside. The clear layer works effectively to minimize the noise of the foil.
