How to judge the quality of high-efficiency filter

How to carry out efficient Filter quality testing? In dust-free workshops where precision parts are processed, in order to ensure clean air, clean air conditioners are usually installed with high-quality high-efficiency filters. Then What are the effective quality inspection methods for filters? Let’s take a look!

1. Before installing the high-efficiency filter , How to perform high-efficiency filter quality inspection ?

As we all know, the quality of a high-efficiency filter is reflected by its density, so for newly unpacked high-efficiency filters The water seepage method is one of the commonly used detection methods. Before replacing or installing the high-efficiency filter, you can easily detect the quality of the high-efficiency filter by placing the high-efficiency filter on a flat table or ground and spraying some water on the surface filter paper.

If left for a few minutes, water droplets have penetrated into the filter paper of the high-efficiency filter, indicating that its raw materials are fake and shoddy products. Even if it is installed and put into use, the indoor air quality will not reach Less than production requirements.

If the water droplets begin to penetrate into the filter paper of the high-efficiency air filter after 2-5 hours, it means The quality of high-efficiency filters is poor. Although the price is low, it can barely meet the production requirements, but its service life is short, which will increase the power consumption of cleaning air conditioners. Therefore, corporate buyers need to consider the cost before making a choice.

If the water droplets begin to penetrate into the filter paper of the high-efficiency air filter after 12 to 15 hours of standing The quality of the filter is very good. If after 24 hours of standing, water droplets still have not penetrated into the filter paper of the high-efficiency air filter, it means that the high-efficiency filter is of very good quality and is worth choosing.

2. After using the high-efficiency filter for a period of time,How to perform high-efficiency filter quality testing?

As we all know, the service life of high-efficiency filters is limited, and they should be replaced when their quality declines. After the high-efficiency air filter has been used for a period of time, we can check the quality of the high-efficiency air filter through various methods.

If the air conditioning unit in the dust-free workshop is equipped with a differential pressure gauge, when the current differential pressure is 2~3 of the initial resistance times, it means that the quality of the high-efficiency air filter has declined, and replacement can be considered.

For dust-free workshops without differential pressure gauges, the quality inspection of high-efficiency filters can also be carried out through observation. If you find that the color of the filter paper material on the outlet side of the high-efficiency filter is black, or if you find too much dust on your hands when touching the filter surface, you should consider replacing it in time.

In order to ensure the air quality in the dust-free workshop, manufacturers need to regularly check the quality of high-efficiency filters to ensure the precision of production Parts meet factory standards.
