Smoke pipes for Range Hoods!
There are generally three types of smoke pipes for range hoods: flexible aluminum foil air ducts, polypropylene pipes (plastic) and PVC pipes. Pipes made of PVC are not common. This kind of pipes is generally used for relatively long flue such as 3-5 meters. The smoke exhaust effect of the distance pipe is still very good.
There are two common pipes, flexible aluminum foil air duct and polypropylene pipe. Objectively speaking, some manufacturers standard aluminum foil tubes are shorter in length, and standard polypropylene (plastic) tubes are generally of moderate length. All in all it’s about making a profit.
The advantage of the aluminum foil tube is that it is opaque, no matter how much oil stains are on the outside, it will look “clean”. Secondly, the heat resistance of flexible aluminum foil air ducts is better than that of plastic pipe fittings. The advantage of the polypropylene tube is that it is easy to maintain and replace. The front and rear connections are screwed for easy disassembly, but it is a transparent tube. Therefore, the disadvantage of plastic pipes is that they are transparent and easy to find that the smoke pipe is dirty, which causes “unsightly”; the second is the heat resistance, the heat resistance of polypropylene is not as strong as that of flexible aluminum foil air ducts, only 120 ° C, but this is not suitable for the oil fume of the range hood. It is completely competent.
