What is a DC cooling fan?
DC fans also known as DC Brushless Fans are basically cooling fans
engineered to meet requirements such as higher air flows at high
static pressures. RENGANG manufactures Brushless DC fans in varied
sizes ranging from 60 mm to 280 mm. These fans are available in the
plastic blade as well as the metal blade.
What are axial fans used for?
In general, an axial-flow fan is suitable for a larger flow rate
with a relatively small pressure gain and a centrifugal fan for a
comparatively smaller flow rate and a large pressure rise. They are
used to supply fresh air, suck air from return air trenches, suck
air from rotary filters, exhaust air out, etc.

1. What is DC Fan and AC fan?
DC fan is power by DC voltage, which normally is 3V, 5V, 12V, 24V,
48V, 60V, and 72V.
AC fan is power by AC voltage, which normally is 110V, 220V, and
380V.
2. How to choose a DC fan?
1) Fan size
2) Voltage of power
3) Current you expect
4) Speed you expect
5) Airflow you need.
6) Noise level you expect.
7) Lifespan of the fan.
8) If you need the FGRDPWMSoft Start function.
3. What is the delivery time?
Sample lead time:3-5 days
Mass production lead time: 1 -3 weeks(depend on the quantity)
Delivery Ways: DHL, UPS, Airfreight, Sea freight, etc.
4. How do we carry out quality control?
There are more than 20 processes to making a fan, our production
procedure follow ISO9001:2008, we need to control every process
well.
1) Bearing: NMB from Japan which will ensure the working life.
2) ICMos and other electronic components, our suppliers include
ROHM IR DALLAS Feeling Technology, and other famous brands.
This can ensure the fan working in complex environments, like the
changeable voltage, etc.
3) Life testing, all of our projects will be testing for 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) We have experience of making high-quality fans for more than 12
years, all of our fans can work more than 50000H in normal
condition if two balls bearing. and 25000H when sleeve bearing.
5) All of our fans will be tested at least twice when they are in
the product line, like currentspeednoisewave form and others,
and 5-10% will be on random inspection.
5. Do you accept OEM? Can we print our own logo?
Yes! We accept OEM services. You are most welcome, please give us
your design and requirement.
Also, we can help you to make some relevant certifications like
RoHS, CE.
6. What can I do if we can not find a suitable fan model on the fan
list?
Please contact us for customized fans.
