DESCRIPTION Single layer aluminium extended liner composed by a 0,08 mm thick corrugated aluminium wall. Being the result of years of experience, its manufacture is accomplished by a process of contemporary seaming and shaping of a single superimposed sheet, ensuring an outstanding resistance. Good mechanical and functional characteristics both in terms of resistance to traction and compression are ensured by its structure. The outer corrugated keeps the liner flexible as required during the installation phase in case of trajectory deviations; thanks to its bending ability installations are easy to perform while maintaining the internal diameter cross section.

USE Allumax aluminium extendable is suitable for ventilation systems and domestic or industrial air-conditioning, aspiration (welding fumes or dust/debris), dryers and stove hoods up to 300°C and for aluminum-compatible applications. Allumax aluminium extendable and with pre-tapered inlets and can be protected by a termoretractable plastic layer.
