FAQ.

1. What is a DC Axial Fan?
A 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 DC fan?
To choose a DC fan, you should consider the points below
*fan size(mm):
*fan speed(rpm):
*fan airflow(cfm):
*fan noise level(dBA):
*fan start voltage(v):
*fan current(A):
*fan connector:
3. What is a Bearing?
Fan bearing includes Sleeve Bearing, Hydraulic Bearing and Ball Bearing, life expectancy of sleeve bearing fan is 30000 hours, hydraulic bearing fan is 40000 hours , while ball bearing is 55000hours or more.
4.What is the divery time 
Sample lead time:2-5 days
Mass production Delivery lead time: 1 -3 weeks
Delivery Ways: DHL, UPS Door to Door service, By Air, By Sea, etc.
5. What can I do if we can not find the suitable fan model in the fan list?
Please feel free to contact us for customized fans.
* Such as: moisture roof, water proof, turbocharger, soft start, Reversible, temperature control, PWM speed control, the RD alarm and the FG signal etc.
IP 55: Protection of motor and PCB board against splashed water and humidity.
Speed signal: The fan uses a separate wire to output information about its speed, and thus about the speed of the rotor.
PWM control input: The speed of the fan can be changed via a pulse-widthmodulated signal. This signal is applied to a specially provided wire.
6. 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 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.
*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.
