When choosing a DC fan for the first time, because there is no concept about the air volume and noise of the DC axial fan, and the price of the DC axial fan may be unclear, so when choosing a DC axial fan, there is no way to start. If this is the case, it can be done easily in three steps
Step 1: Choose a DC fan of the largest size that you think can be installed, determine the voltage, and ask the supplier of the DC axial fan to do a test to see the effect. If the sample is not too suitable, confirm the relevant parameters by the following method
Because the fan speed is proportional to the voltage, increase the voltage by 20% or decrease by 50%. If you adjust to which voltage value, you can test the air volume and noise. Write down the voltage value at this time. The supplier designs a 12V fan according to the speed and air volume of this voltage
Step 2: Redesign the DC axial fan according to the parameters confirmed by the customer. (Of course, if the first step cannot achieve the desired effect in any way, the fan size needs to be changed. At this time, you can discuss the new size with the fan supply and follow the first step)
The third step: According to the product warranty time and the harsh environment, choose what kind of bearing to use, which directly affects the cost of the Dc axial fan. The life of oil-impregnated bearings is 20,000 hours under normal temperature and normal conditions, and the life of double ball bearings is 50,000 hours under normal temperature and normal conditions. In high temperature and dusty environments, the life of oil-impregnated bearings decreases faster than that of double ball bearings. Of course, the price Also cheaper
