Description of forwards centrifugal fan:
Centrifugal fan is a mechanical device for moving air or other gases in a direction at an angle to the incoming fluid. Centrifugal fans often contain a ducted housing to direct outgoing air in a specific direction or across a heat sink.
These fans increase the speed and volume of an air stream with the rotating impellers.
Features:
- Centrifugal fans are Suitable for various speed regulation methods such as frequency conversion speed regulation and variable voltage speed regulation.
- Easy installation, stable and reliable operation, high efficiency and no overload in power curve.
- Large static pressure, large air flow and low noise.
- CE, ROHS Certificates.

Workshop:
1. How to choose a centrifugal fan?
1) Fan size
2) Voltage of power
3) Current you expect
4) Speed you expect
5) Air flow you need.
6) Noise level you expect.
7) Lifespan of the fan.
2. What is the delivery time?
Sample lead time:3-5 days
Mass production lead time: 2 - 4 weeks(depending on the quantity)
Delivery Ways: DHL, UPS, FedEx, Air freight, Sea freight, Railway Freight, etc.
3. Do you accept OEM? Can we print our own logo?
Yes! We accept OEM services and logo printing, welcome! please tell us your design and requirement.
Also we can help you to make some relevant certifications like RoHS, CE, UL.
4. What can I do if I can not find the suitable fan model in the fan list?
Please feel free to contact us for more information.
5. What about your quality control?
1) Our production procedure follows ISO9001:2015.
2) Import high-quality bearings abroad, such as Japan, that will ensure the working life.
3) All of our projects will be tested more than 1 year in such an environment: temperature is 60°C, voltage is more than 20%( such as: 24V, the testing voltage is 28V), and the power restarts every 2 minutes.
4) All of our fans can work more than 50000 hours in normal condition with ball bearing, and 25000 hours with sleeve bearing.
5) All of our fans will be tested at least twice when producing and before shipping, like voltage\current\speed\noise\wave form\air flow and others, and also 5-10% will be on random inspection.
