Each size, each operating voltage, and each PCB type of 3PCS axial flow fan with a maximum rotational speed were subjected to accelerated aging tests in an oven at 90 °C. This test condition is representative of the worst operating condi...

The difference between brush and brushless DC fan is mainly in principle, the performance is superior, the specific differences are as follows: 1; A commutator need to use a brush for electrical coupling, a no brush, commutation by elect...

Characteristics of DC COOLING FAN? DC COOLING FAN is not unfamiliar to modern people, it is an indispensable cooling equipment in modern industrial machinery, cooling effect, long service life, simple and convenient operation, so DC cool...

The axial flow fan can be used in high-rise buildings, underground buildings, tunnels, drying rooms and other ventilation or high-temperature smoke exhaust. It can run continuously for more than 30 minutes at 280 °C. It can run continuou...

How should the axial flow fan eliminate the noise? We use axial flow fan is mainly to ventilate, but the fan can bring good results, but also produce greater noise, then axial flow fan need to use what method to reduce noise? Noise from ...

LOW NOISE AXIAL FAN is a new type of axial fan with energy saving and ultra low noise. By adopting the structure of the blade with the same pitch and wide forward sweep, the separation of air flow on the blade surface and the formation of a...

1, the motor pole number is too high, the motor spindle speed is slow, the air volume is small;2, the Blade Angle is small, the air volume is small;3, the Axial Flow Fan impeller craft is unreasonable, the aerodynamics is...

Before installing a fan, first understand the difference between the axial flow fan and the centrifugal fan, and the matching relationship between the flow and pressure system of the Fan;. First of all, the difference between Centrifugal...
