High temperature aluminium foil ducts are not unfamiliar, they are the aluminium foil ducts used for the exhaust of many hoods. It is a high-temperature duct for ventilation, exhaust and fume extraction purposes and is a very common type of duct among the high-temperature resistant types. The silvery-white appearance of this duct is not only fireproof, oilproof, waterproof and heat-resistant, but also has a relatively high appearance, which raises the profile of the equipment. Of course, this is only one of the types of duct we usually see, but it is not the only type of aluminium foil duct on the market.
Single-layer or double-layer pure aluminium foil duct
Aluminium foil air ducts are commonly used for hoods and smoke exhausts. The disadvantages of this type of duct are that it is very thin and lightweight, and it is easy to break; the advantages are also more, such as lightweight, waterproof, oil-proof, fire-proof, dust-proof and cheap. So it is the choice of many manufacturers and shops.
Aluminum foil glass fiber flexible duct
Aluminium foil composite ventilation hose, generally in a three-layer structure. It is made of high quality aluminium foil (one layer) with a layer of imported glass fibre fabric bonded to the outside and supported by spiral steel wires on the inside. Because of the bonded layer of glass fibre fabric, it is more resilient and does not break as easily as a pure aluminium foil hose, and has high stretch, excellent bendability and easy construction. The high temperature resistant aluminium foil composite ventilation hose is commonly used for hot and cold air guidance, high temperature exhaust gas discharge, motor vehicle layer gas discharge, constant temperature gas transport, high temperature welding gas discharge, granule dryers for the plastics industry, printing machinery, blowers and compressors, engine heating and various other machinery ventilation and exhaust air. It is resistant to high temperatures, acids and alkalis and is extremely flame retardant.
Clamped aluminium ducts
This type of duct is made of thicker aluminium foil and has a durability and temperature resistance that cannot be compared with the previous two types of aluminium foil. The inner clamped composite aluminium foil duct is made of silver white high temperature resistant dust free 0.1mm thick composite aluminium foil, internally made of 8mm wide and 5mm thick fluted sub-lead support metal sheets in a spiral continuous tight clamping, delicate and easy to bend, construction resistant to medium temperature, suitable for clean room use. This aluminium foil duct has the advantages of high winding, temperature resistance to 130 degrees and hot air equipment.
