Haier humidifier
Air duct can be divided into rigid and flexible according to its material mechanical properties.
(1) Rigid air duct
It is generally rolled from 2~3mm thick iron plate. The iron air duct has the advantages of durability, long service life, and all kinds of ventilation methods can be used. The disadvantages are high cost, easy corrosion, bulky, inconvenient disassembly, loading and transportation, and difficult to use in curved tunnels. The use of iron air ducts in coal mines is decreasing. In recent years, GRP air duct has been produced. Its advantages are lighter than iron air duct (its weight is only 1/4 of steel), strong acid and alkali corrosion resistance, small friction resistance coefficient, and higher cost than iron air duct.
