FAQ :
1 . What is a DC/AC Axial Fan?
An AC/DC fan is usually powered by 3v , 5v , 12v , 24v , 36v and
48v . It blows air along the axis of the fan , or parallel to the
track of the blade axis . Standard DC Axial fan sizes include 20mm
, 30mm , 40mm , 50mm , 60mm , 70mm , 80mm , 92mm , 120mm , 150mm ,
and 200mm .
2 . How to choose a AC/DC fan?
To choose a AC/DC fan , you should consider the points below
a . fan voltage
b . fan current
c . fan speed
d . fan airflow
e . fan noise
f . fan lifespan
3 . What is a bearing?
Fan bearing includes Sleeve Bearing and Ball Bearing , life
expectancy of sleeve bearing fan is 30000hours , while ball bearing
is 50000hours or more .
4 . How do we carry out quality control?
Usually , there are two ways to monitor reliability during the
manufacturing process .
a . Early Life Test
This is used as a mean 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 50°C+/-5°C for 24 hours .
b . On-going Reliability Demonstration
This is a longer-term program aimed at providing data on continuous
basis to demonstrate the reliability of product . 10 units per
month are randomly collected from one of the production lines for
burn-in for 168 hours at 50°C+/-5°C . Units are monitored and
tested on daily basis . Failed units will be analyzed and
corrective actions taken where necessary .
5 . What can I do if we can not find the suitable fan model in the fan list?
