Air filter is a kind of filter, which is a specific kind of filter, and will often be used as a filter, the object of its use is air or compressed air, through the use of this filter, to achieve the purpose of purifying the air. Therefore, we need to have a comprehensive understanding and understanding so that we can carry out this operation well, rather than using it wrong.
1. How long can the filter core of the compressed air filter in the air filter last? What are the common specifications?
Compressed air filter, this is a specific type of air filter, and there are many applications, can be used in many industries. And filter element, this is an important component of compressed air filter, is playing an important role in filtration, its replacement cycle, generally about half a year to a year should replace the new filter element, so the use of filter element cycle of this component, is about half a year to a year.
The compressed air filter is used to remove the dust and impurities in the compressed air and separate the moisture from the air. The degree of filtration of the filter refers to the upper limit of particle size allowed by the filter. On the commonly used specifications of filters, there are four kinds of 5 - 10um, 10 - 20um, 25 - 40um and 50 - 75um.
2. Why are air filters widely used?
Air filter is widely used because it collects dust from gas-solid two-phase flow through porous filter material and purifies the gas. The air with low dust content is purified and sent into the room to ensure the technological requirements of clean rooms and the cleanliness of air in general air-conditioned rooms. Therefore, based on this point, this kind of filter can be applied to many industries and fields, to have a wide range of applications.
3. How to determine the rated air volume of the air filter? Is the wind equivalent to the rated air volume?
The resistance of an air filter varies with the wind speed on the windward side or with the filter speed. When designing and finalizing the air filter, the installation position of the product in the air-conditioning purification system, the structure, the filter efficiency and the filter resistance should be taken into account. The surface wind speed of the filter can be determined by these considerations. And get the specific parameters of rated air volume.
In engineering design, the selection of air filter is not necessarily equal to its rated air volume, but slightly higher than the rated air volume under some specific conditions. However, in practical design work, it is considered that the selection of air filter below the rated air volume to achieve the purpose of saving energy consumption and prolonging the service life of air filter.
