The development trend of ventilation duct in ventilation application industry.

Since the duct fan was put on the market, due to its excellent performance and low operation cost, its application in ventilation and air conditioning systems has been continuously promoted. At present, most products are also widely used in shipbuilding, ventilation, purification, bridge dust removal, airports, tunnels and other construction industries.

The main uses of ventilation ducts are as follows:

(1) Ventilation system: supply fresh air and exhaust gas, discharge harmful gas outdoors, and deliver outdoor fresh air indoors. Generally speaking, the flow of the ventilation system is very large, so it is required to use air conveying pipes with small resistance to save costs and operating costs - ventilation pipes are the most suitable. Generally, galvanized iron pipes are used, and stainless steel pipes are used in corrosive and especially humid places.

(2) Air conditioning system: the ventilation pipe can be pasted with thermal insulation materials, and the appearance is beautiful.

(3) Oil fume exhaust system: There is a large amount of oil fume in the kitchens of hotels, restaurants and hotels, which needs to be discharged. The use of ventilation ducts is appropriate, strong, economical and practical.

(4) Dust removal system: the collection and transmission of dust removal device can use ventilation pipes.

(5) Bulk material conveying: pneumatic conveying system is a kind of system. Some fine and loose material particles can be conveyed by ventilation pipes, with low cost and good effect.

Duct fans are mainly used in industrial and architectural projects, and the application fields mainly involve: electronic industry dust-free plant purification system, pharmaceutical food aseptic workshop purification system, central air conditioning system of hotels, shopping malls, hospitals, factories and office buildings, dust removal, smoke exhaust, oil suction and other exhaust pipes for industrial pollution control, air supply pipes for industrial environment or post comfort, gas drainage systems for coal mine gas drainage Air supply and return system for environmental control of coal mine, etc.
