AXIAL FANS

Dongguan Wanhang Electronics Technology Co, Ltd. is a professional cooling fan
manufacturer. We provide DC Micro Fans, axial fan propeller, dc axial compact
fan, axial fan for ventilation, cooler axial, DC Micro Blowers, dc brushless
cooling fan and so on. Want to know more? Please contact us. If you want to buy
one, we will give you the axial fan static pressure and axial fans
specifications.

WHEE manufactures certified DC China axial fan . The range is from 40-120mm.
The core materials for axial flow fan/clooer are all imported, waterproof and
dustproof grade IP56, intelligent control design such as PWM and temperature
control, etc.

Configuration of industrial axial fans run quitely. For moving large volumes of
air, axial cooling fun is ideal. Design of compact axial fans saves
installation space. Compared with centrifugal funs and blowers, axial fans have
higher operating speed, require a low power input for operation, and the
airflows they create are of low pressure.
Axial Fans Standards

Temperature 25℃ and relative humidity 60% shall be the standard if no doubt
arises in the judgment. However, it is permitted that tests are conducted in
the environment of temperature 5~35℃, relative humidity 45 ~ 85%.

Insulation resistance: At least 10 MΩ at 500VDC between the internal stator
and both lead wires.

Dielectric strength: Applied a 500VAC for 1.0 minute or 600VAC for 2 seconds
between housing and both lead wires.

In accordance with the Restriction of Hazardous Substances(ROHS)Directive, WHEE
DC cooling fans have complied with law and discipline not to employ the
forbidden substances, and restrict the allowable concentration of some limited
substances deliberately in our components.

Axial Fans FAQs
How Long Is Your Axial Fans Wire Length?
Wire length and the terminal can be customized according to your requirements,
default wire length is 200mm.

What Kind Of Function Can We Choose For Axial Fans?
Auto-restart, Speed detection, Stoppage Alarm, Waterproof, PWM function,
Temperature control. The commonly used functions are as follows:



PWM speed regulation function:

PWM is a kind of frequency conversion speed regulation, namely pulse width
regulation.

By adjusting the pulse width on the fundamental wave, the voltage and frequency
of the sine waves can be adjusted, so as to adjust the speed of the motor.



FG speed measurement function:

Depending on the temperature change, the hall element generates pulses and then
detects the pulse frequency to measure the speed.

Every turn of the fan, the internal detection circuit will send 2 pulse signals
from the speed measuring line (usually yellow) to the counting circuit on the
motherboard. The speed measuring chip of the motherboard only needs to
calculate how many pulse signals it receives per second or per minute to
realize the speed measuring



RD alarm function:

RD signal, whose function is to output low level when the fan is running, and
high level when the fan is not running. By detecting this signal, the CPU can
know whether the fan is running normally.



TC temperature control function:

According to the CPU load and temperature adjust the speed, low load low
temperature can reduce the speed, reduce noise, prolong the life of the fan,
high load high temperature automatically increase the speed, conducive to heat
dissipation.

How Long is WHEE Axial Fans MTTF?
The different bearing type has different MTTF. Two ball bearings can last up to
50,000hrs; F.D. The bearing can last up to 40,000hrs; Sleeve bearing can last
up to 30,000hrs when operated at 40℃ and 45 ~ 85% relative humidity of the
specified voltage rating.
