How about the Application of the external rotor coaxial duct fan?

1.It can effectively adjust air, remove moisture, dust, odor, make indoor air clean, fresh, has gradually replaced the traditional axial flow fan for exhaust, it makes up for the lack of axial flow fan static pressure phenomenon.

2.Widely used in family, apartments, villas, rooms, shopping malls, hotels, restaurants, movie theaters, dance halls, railway stations and other places

3.The fan can be also used for all kinds of welding fume, can effectively eliminate the welding when the poisonous and harmful gases, smoke, etc., improve the working environment.

4.YFZ Series External Rotor Coaxial Duct Fan is a radial fan. The equipment has compact structure, high capacity and easy installation, YFZ fan can resist high pressure and fit long pipeline operation while operating at low noise.

5.YFZ series motor has moisture resistance and can be installed in most environment. These fans should fit IP44 grade when being installed in the pipeline system. They cannot be used for conveying abrasive powder, soot and similar materials. Its shell is made of prefabricated galvanized steel.

6.YFZ series motor is suitable for long-distance transmission of hotels, clubs, supermarkets, storerooms and restrooms, and places which have noise requirement.

Advantage of the external rotor

Structure: The new outer rotor fan’s impeller is mounted directly on a rotating outer rotor’s excircle , impeller rotates together with the external rotor motor, motor’s main shaft is stationary.

Stability: impeller and external rotor are fasten to the outer rotor’s excircle by soldering or press fitting to form a whole. No secondary assembly errors, greater reliability and stability, less vibration.

Performance: more energy efficient, the national energy efficient products.

Noise: impellers after aerodynamic design again to ensure that the premise of wind capacity, lower noise, high efficiency, energy saving effect is more obvious.

Cooling: The motor is mounted in the middle of the fan impeller, better thermal performance, The motor itself has reached the maximum cooling effect and longer life.   

Shape and weight: whole elegant appearance, elaborate design, the fan’s axial length is much shorter, compact structure, saving installation space, the installation more convenient and flexible. Due to optimize the product structure design, small size, lighter weight.
