Product description

I. Features of fan
YDW series low-noise centrifugal fan is a kind of new energy-saving centrifugal fan that is consisted of parts such as advanced multi-blade impeller, logarithmic spiral casing, built-in direct-connected low noise three-phase asynchronous motor with outer rotor, arc streamline inlet, etc. The fan is structured as a double-inlet one and is novel in structure, small in dimension, large in air flow and low in vibration. The motor can lower the voltage through three-phase voltage regulator, achieving stepless speed regulation to adapt to location where the air flow frequently changes, so it is an ideal accessory product in operations of air-conditioning, purification, refrigeration and automobile spray booth.


II. Fan structure
YDW series low-noise centrifugal fan is mainly consisted of casing, impellers, air inlet, motor, etc.
1. The casing is made by high-quality steel plates with plastic-sprayed surface or galvanized steel plates with weld-free seam. It is fine in appearance, resistant to heat and humidity and durable in use.
2. The impeller is made of forward multi-blade circular arc blades riveted with front and middle discs. It is made of fine machined galvanized steel plates and all the parts of the impeller are formed by one-time stamping forming in mold to ensure its accuracy. It is then calibrated through static and dynamic balance after forming, so it is smaller in vibration when in operation, excellent in pneumatic performance, low in noise and stable in operation.
3. Air inlet is made of galvanized steel plates subject to processing by mold. It is mounted on both sides of the fan with curved section parallel to axial direction that makes the smooth air flow and less loss.
4. Motor: The low noise three-phase asynchronous motor with outer rotor is adopted. The impeller is bolted to motor as a whole to reduce transmission loss, enhancing the whole efficiency of fan. Change of fan delivery can be achieved by adjusting the rotation speed of fan through three-phase voltage regulator or frequency conversion governor.
 5. The fan can be made in the form of either Right Rotation or Left Rotation. When it is viewed from the front of the motor, the fan is a right-rotation one in case that its impeller rotates clockwise, otherwise it is a left-rotation one. The fan outlet can be made with several angles such as 0°, 90° or 180° (as shown below).


III. Application
1. It is applicable to indoor ventilation of buildings such as factory, hotels, halls and hospitals etc., as well as support to various central air-conditioners and frame type air-conditioning units. It is especially applicable to air-conditioning units of variable air volume and low noise.
2. It is suitable to be used along with various purification equipment.
3. It is suitable to be used along with various coating, dedusting and smoke exhausting equipment.
4. It is applicable to ventilation of various kinds of automobile spray booth and drying room etc.


IV. Notes to user
1. The medium transmitted by the fan is air and gas that is non-corrosive, resistant to explosion and free from viscous substance. And the dust and hard particulate matter contained in the medium shall be no greater than 120mg/m3.
2. The casing of fan shall be well earthed.
3. It is prohibited to use the fan in a full open way. Instead of required power in case of full opening of air outlet, the power of motor for the fan refers to internal power multiplied by the reserve coefficient of motor capacity under specific condition, so it is prohibited to run the fan without any external load to prevent the motor from being burned out due to over-power operation. It shall run in specified current, otherwise the motor will be burned out due to over-load power.
4. In order to ensure safe operation of the fan, open-phase protector for motor must be equipped at the time of installation.
5. It is prohibited to pull power cable of the motor when loading, transporting and moving the fan whose parts shall not be crashed or squeezed by hard objects. Don't stack them in a place where there are humid and corrosive materials.
6. During the operation of the fan, it shall be stopped immediately by cutting power supply in case of abnormal sound, fierce vibration and so on. Operation can't be recovered before troubleshooting.
7. When an order is placed, some parameters of the fan must be instructed, such as, model, specifications, flow, total pressure, rotation speed, direction of outlet and left-rotation or right rotation.
8. Please instruct the special requirements if there are any special requirements at the time of placing order.
9. Please be noted that any change to the product will not be notified one by one.
