Cooling fan for annular cooler

Our fans satifsty requirements of cooler. They are power saving and high efficient with excellent design.

Structural Features:

1, single-suction; single-support
2, motor and fan by type coupling
3, Rolling Bearings
4, arc collector
5, cone curved front disc
6, airfoil blades
7, streamlined shaft drive

Advantages:

1, high efficiency, low shaft power
2, smooth operation and high bearing capacity
3, low noise, small vibration
4, long working life

General Features:

1.Advanced design originated from Japan
2.Efficiency up to 85% -90%, 10% higher than the domestic technology; save energy 10% -30%, and high pressure head, wide flow range, wide efficient area, flat performance curve.
3.Anti-fouling design. Special shape of the impeller and a higher critical speed can avoid the accumulation of dust on the impeller, improve the Fan running smoothness and reduce vibration, extend Fan working life.
4.Antiwear measures. Under the premise of the Fan high efficiency, the measures consider different stage of production line and parameters, and extend the Fan working life.
5.Low-noise. Streamlined products designed according to aerodynamic theory, excellent manufacturing quality and effective measures to avoid noise, all these guarantee the Fan noise to satisfy user and environmental requirements.
6.Custom-made for customers. We design according to the actual working conditions and operating parameters for the Fan, so as to make the operating point closer to the maximum efficiency point of the Fan. We will play our own strengths, tailor-made, carved, to create a first-class and power saving Fans.
