u003cpu003e From the development trend of ventilation duct
s in recent years, it can be seen that the application of ducts is increasing day by day. This is because consumers have clearly realized the advantages of ducts, and the emergence of ducts in the ventilation industry A great success has been achieved. Now, in addition to the ventilation industry, the development of air ducts in all walks of life is also very good. Let’s take a look at the advantages and characteristics of air ducts!u003c/pu003eu003c/pu003eu003c pu003eu003c/pu003eu003cpu003e 1. Ventilation system: send fresh air, exhaust air, discharge harmful gas to the outside, and send outdoor fresh air to the room. Generally speaking, the ventilation system has a large flow rate, so it is necessary to use low-resistance gas pipelines to save costs and operating costs. Galvanized iron pipes are generally used, and stainless steel pipes are used for particularly corrosive and humid places. u003c/pu003eu003cpu003e 2. Air-conditioning system: Insulation materials can be pasted inside the ventilation ducts, and the appearance is beautiful. u003c/pu003eu003cpu003e 3. Oil fume emission system: Hotels, restaurants, and hotel kitchens produce a lot of oil fume, which needs to be discharged. The ventilation ducts are suitable, strong, economical and practical. u003c/pu003eu003cpu003e 4. Dust removal system: The ventilation duct can be used for the collection and transportation of dust removal equipment. u003c/pu003eu003cpu003e 5. Bulk material transportation: pneumatic conveying system, some small loose material particles can be transported through ventilation pipes, with low cost and good quality. u003c/pu003eu003cpu003e 6. Good fire resistance: The current common problem is that the combustion performance and fire resistance limit of finished ventilation ducts have not been tested by relevant national departments, and the combustion performance and tube wall thickness of some ventilation duct materials do not meet the requirements. u003c/pu003eu003cpu003e 7. Low cost: Compared with traditional brick ventilation ducts, ventilation ducts can save about 40% of the project cost. u003c/pu003eu003cpu003e 8. Lightweight and high strength: Compared with traditional brick ventilation ducts, magnesite ventilation ducts have lighter weight and high strength, which can greatly reduce the load on buildings. u003c/pu003eu003cpu003e 9. Flexible design: The ventilation duct can be adjusted at any time according to the size of the reserved hole. u003c/pu003eu003cpu003e 10. Unique design: A flue gas check valve and a fire isolation door are installed on the opening of the ventilation duct, which can effectively prevent odor and fire. u003c/pu003eu003c/pu003eu003cpu003e 11. Ventilation duct construction is simple: increase the indoor space, with good airtightness, no return of smoke, no return of odor, which can greatly improve the indoor environment. u003c/pu003eu003cpu003eu003c/pu003e u003cpu003e
