    FAQ

     

    1.  What is AC, DC and EC Axial Fan?

    AC fans are powered by 110-220v, 200-240v, 380-420v.

    DC fans are usually powered by 3v, 5v, 12v, 24v, 36v and 48v. They blow air along the axis of the fan, or parallel to the track of the blade axis. 

    EC fans are powered 110-220v, and they can transfer AC flow to DC flow.

      

    2. How to choose a fan?

    To choose a fan, you should consider the points below

    *fan voltage

    *fan current

    *fan speed

    *fan airflow

    *fan noise

    *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 55000hours or more.

     

    4. 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.

     

    5.What is the divery time 

    Sample lead time:3-5 days

    Mass production Delivery lead time: 1 -3 weeks(Depend on the quantity)

    Delivery Ways: DHL ,UPS Door to Door service ,By Air ,By Sea ,etc.
