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.

Q4. What are your payment terms?
We accept payment by T/T, Trade assurance order of Alibaba.Accept
50% deposit +50% balance.
Q5. What are DC Fan and AC fans?
A2: DC fan is power by DC voltage, always is 5V, 12V, 24V, 48V,
60V, and 72V.
AC fan is power by AC voltage, always is 110V, 220V, and 380V.
Q6. How do we carry out quality control?
Usually, there are two ways to monitor reliability during the
manufacturing process.
* Early Life Test This is used as a means of process control aimed
at identifying any latent manufacturing problems and determining
the effectiveness of burn-in. Every day, 5 samples will be picked
up randomly from one of the production lines for burn-in at
50C+/-5C for 24 hours.
*On-going Reliability Demonstration This is a longer-term program
aimed at providing data that continues to demonstrate the
reliability of the product. 10 units per month are randomly
collected from one of the production lines for burn-in for 168
hours at
50C+/-5C. Units are monitored and tested on daily basis. Failed
units will be analyzed and corrective actions are taken where
necessary.
