Air hose AL THERM

steelpolyesterpolyolefin

Flexible hose made of AL/PET/AL (aluminium/polyester/aluminium) wall and steel wire helix. Thermo-insulating covering in polyester fibre (th. 25mm/16kg/m3). Outer anti-steam protection in aluminized polyolefin film (flame retardant). The sturdiness of the heat-bonded polyester fibre prevents dispersion of microfibres during air flow.
