Apakah perbezaan antara Saluran Kerajang Aluminium dan Saluran Kerajang Aluminium Separa Tegar

What is Aluminum Foil Duct

Made of flexible aluminum foil, ini adalah jenis yang paling biasa untuk saluran peralihan pengering — saluran yang bersambung dari perkakas ke saluran utama yang mengalir ke luar. Saluran kerajang boleh akordion dari kira-kira 1 kepada 8 kaki, yang biasanya cukup untuk kebanyakan pemasangan.

Transition ducts must not be concealed inside walls or other building cavities and usually have a maximum allowed length of 8 kaki. Foil duct is held in place with dryer clamps or large hose clamps. Metal tape can be used, too, but clamps make it easier to remove the tubing for cleaning.

What is Semi-Rigid Metal Duct

Semi-rigid metal (usually aluminum) duct is flexible and similar to foil ducting but quite a bit more rigid. Like foil duct, semi-rigid is used only for transition ducting and should not be concealed in walls or floors. It is typically installed with clamps. Although semi-rigid metal duct is often stronger and has a smoother interior (catches less lint) than foil duct, it is more common to find listed foil duct than listed semi-rigid.
