How do you know if a DC fan is good or bad
1. First see whether the performance of axial flow fan in line with the actual air volume pressure, in line with the actual model, in order to achieve the actual demand for air volume. 2. Bearing parts of the vibration value is not high, high vibration value fan bearing easy to damage, vibration value low bearing long life. 3. Good axial flow fan from the appearance can be seen, the more high-quality Fan, the appearance of the more fine, more attention to details, and so on, the better axial flow fan. 4. The axial flow fan operation efficiency is not high, high efficiency energy saving, low efficiency power consumption. 5. Buy fans to buy a market reputation, look at the fan manufacturers operating years and scale. 6. Axial flow fan running noise how, high noise impact the working environment, but also more energy consumption. Kill. When buying axial flow fan, need to consider the convenience of maintenance, axial flow fan equipment is the need for regular maintenance, so these need to be considered within the scope.
