Double Inlet Centrifugal Fan with External Rotor Motor AC Single Phase 110V 220V Blower Motor
Double Inlet Centrifugal Fan with External Rotor Motor AC Single Phase 110V 220V Blower Motor
Centrifugal fans can be manufactured to various casing thicknesses and with various forms of construction according to usage. Thus at one extreme they can be handling clean air whilst at the other, air or gas handled can be at a temperature well above ambient and/or may contain substantial quantities of moisture and/or solids. It may also be at high pressure such that loadings on the fan casing and the associated ducting system are much higher than usually expected for a HVAC fan.
Connection to the ducting may be via flexible connections, or alternatively may be directly connected. In the latter case the fan has to withstand additional loads due to the dead weight of these connections. Where gases, or the surrounding ambient atmosphere, are at a high or low temperature, additional loading can result from the effects of expansion or contraction.

AC External Rotor Motor Powered Double-Inlet Housing Centrifugal Fan
2. It is single-phase power input types for the external rotor motor powered centrifugal fan. And the centrifugal fans are widely used in the industries of air conditioning terminal system, IT & Telecom, FFU, Fresh air system, and ventilation, etc.
3. There's a built-in thermal protector for the single-phase motor, and the motor can be operated in the temperature from -30 to 60 degrees Celsius. If the customer needs a built-in thermal protector for the three-phase motor, please note us while placing the order.
4. The speed of the motor can be controlled.
5. We would need the operating point parameters of the motor such as speed, power, and even the assembly size if the customer is only ordering the motor for their application. To get a suitable motor performance, we would prefer an impeller and housing for doing testing and research if the customer is going to use the motor for powering their centrifugal impeller.
6. Noise Level. The noise level defined for our motor fan is the sound pressure level. The distance for doing the noise level test is 1m from the test point to the inlet hose according to the national standard requirements.
7. Average of our motors. The bearing used on our motor is a maintenance-free ball bearing, and the average life rating is L10 which is between 30,000 to 50,000 hours based on different operating conditions.
1.smooth running,
2. long work times and Low temperature
3.low noise,
4.steady performance.
5. Energy-saving
6. Short Delivery time
7.Long life, low noise
8. High efficiency, high reliability

Housing
The housing is made of high quality hot-galvanizing steel sheet. The side plates include inlet cones that are designed with the best aerodynamics for inlet condition. The scroll is fixed to the side plates by spot welding. On the side plate of the housing there are a series of holes drilled in advance for riveting nuts to carry out installation according to air outlet direction needed by the customer.
Motor
YYS series ventilators are equipped with single-phase 220V/50Hz three speed motors,which are flexible to change speed and easy to install. Speed can be changed by using provided silicon controlled voltage regulator and frequency converter. The voltage can be customized based on request.
Centrifugal fan is a new kind of variable speed, high efficincy, and low noise Type centrifugal fan, the fan, compact structure, easy installation, small volume, windhigh pressure, large amount of small vibration, with single phase voltage regulator or inverter, can carry out Strict control speed.especially suitable for noise, big air volume range of ventilated place.
