Feature 

1.CDR Series External Rotor Coaxial Duct Fansis a radial fan. The equipment hascompact structure, high capacity and easy installation. CDR fan can resist high pressure and fit long pipeline operation while operating at low noise

2,Shell: Adopt high quality 1.0 mm deep drawing steel plate, the surface after spray treatment have fire proof corrosion resistance; Some peers adopt 0.6mm tensile plates, the surface after electroplating treatment.  

3,The main motor: Adopt export-oriented high-performance external rotor motor, data through the computer repeatedly optimization, speed is higher 200-400 rpm than the average, wind naturally would not have said, and use the silent ball bearing , continuous life up to 80,000 hours. 

4,Impeller:Use the imported 1.0 mm galvanized sheet, high temperature corrosion resistance superior. 

5,Junction boxes: enhanced with a new high-temperature flame-retardant PP injection molding, Beautiful appearance, first-class high temperature resistant,fire prevention, corrosion resistance, it’s safe and reliable    

6,Installation feet: The widening type installation feet, better stable performance.

7,The product have passed the national secondary energy certification;first-class energy conservation. 

Application

1.Coaxial pipe centrifugal fan is indispensable for modern residential ventilation products, its beautiful shape, 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 also be 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.Operating Environment: Elevation: below 4000m, air humidity: less than 90ºC and ambient temperature: -25ºC~+60ºC for general products, products used in unconventional environment also can be customized.

5.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.The OD of our products:100mm 125mm 150mm 160mm 200mm 250mm 315mm  

Specification

3.D—Three-phase motor,E—Single-phase motor

4.The fan then pipe OD:200-two connected pipe diameter of 200mm 

5.Type code:A-low noise, C-high flow high pressure

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.
