1. Effectively dispose of indoor air pollution, such as dust, to provide a cleaner air;
2. Effectively prevent the appearance of stains around the air supply opening of the air conditioner, and the service life of the equipment of the court;
3. In the clean room of different grades, the corresponding standard requirements are required. If the clean room wants to reach a certain level of cleanliness, then the primary filter must be installed to effectively filter the air entering the room;
4. Disposal of severe ash images in components such as fans, heat exchangers, pipes, etc., and the effect of removing odors.
Today's primary filter is used more and more in various purification systems, many factors have become an important criterion for selection, but the service life of the device is still the most important basis for users to choose this device. However, in actual use, it is difficult to predict the service life of the primary filter. Therefore, the budget is often calculated by the actual weight of the dust contained in the equipment. At the same time, only when the experimental conditions and methods are the same, can it be based on the dust The amount of money to budget is not the same as the life of the device.
The dust holding capacity is the total amount of dust intercepted by the filter before it reaches the end of the experiment, and the experimental method is also very simple, that is, a certain amount of artificial dust is sent to the experimental air passage by the dust generating device until the artificial dust is completely sent. After that, the filter subjected to the experiment was removed and weighed to obtain a change in the mass, thereby calculating the weighting power of the filter device. Repeat the above method until the initial effect filter of the experiment reaches the final resistance value, and the average weighting power of the whole experimental process can be obtained. Finally, the average weighting power × total dusting amount can be used to obtain the filter. The dust holding capacity of the device can also be used to estimate the service life of the device.
