What are the definitions and functions of Fan Filter?
With the continuous development of society, it is inevitable that servers or other electronic equipment will generate a lot of heat during operation. If the temperature is too high, the equipment will be easily damaged. Fan filters have become an important device used in many fields, such as: new energy vehicles, energy storage, photovoltaics, robots, charging piles, high-tech industries, etc., all need cooling fans. Based on the consideration of cost and installation space, especially the modern equipment—cabinets, the cabinets are gradually developing towards high capacity. High capacity means integrating more electronic equipment in a smaller space. The density of device equipment has been greatly improved, and the electrical components of these equipment will dissipate a large amount of heat during actual operation. More and more consumers use fan filter combinations. Not only can it help the device to filter out dust, but it can also ventilate and dissipate heat.
In the electrical industry, pure fans are collectively called cooling fans, and those without fans that are only used for ventilation are called filter screen covers or grilles. Usually, a cooling fan is equipped with a filter cover. The fan is composed of a cooling fan and a fan guard. The cooling fan is used to take in air into the cabinet or exhaust the hot air in the cabinet. The fan guard is used to protect the fan. The filter screen cover is composed of plastic grille and filter cotton, which is used to filter dust and fine particles in the air.
The axial flow cooling fan can be installed in the way of "blowing" or "pumping". The installation direction of blowing or pumping can be selected according to the site conditions. The defensive function of the ventilation grid can prevent mechanical damage and prevent moisture from entering. Grooved grips on the cascade allow quick and easy replacement of filter mats. Non-woven fiber filter mats are used to prevent dust particles above 10 microns. The protection level can reach IP54 level. Vent shutters are protected from rain.
The fan and filter have the characteristics of small size, light weight, and easy installation. And it has the safety performances of large air volume, low noise, small vibration, small electromagnetic interference, low power consumption, safety and reliability.
