Everyone knows that high-efficiency filters are mainly used at the end of clean rooms. Generally, they need to be replaced in about 1-2 years, but this is not absolute, because many users can use them for 2 years or more before replacing them, and it does not affect Use effect, what is the reason? Of course, there are certain skills in everything;
The filter at the front end of the high efficiency filter mainly includes primary and medium-efficiency air filters. If the high-efficiency filter is to be effectively protected, the junior high-efficiency filter needs to perform its due function, which involves how to choose a junior high-efficiency filter The problem is;
Now let's explain-the functional characteristics of the next junior high-efficiency filter:
Medium-efficiency filters are mainly used in air purification and filtration in electronics, precision instruments, machinery, metallurgy, chemicals, textiles, medicine, food and other industries; intermediate filters in air-conditioning systems. Used to capture particulate dust and various suspended solids above 1~3pm; large air volume; small resistance; large dust holding capacity; reusable;
Primary-efficiency filters are generally used for pre-filtration in multi-stage filtration systems; air filtration in general acid-base organic solvents; primary filtration in air-conditioning systems. It is mainly used to capture particulate dust and various suspended solids above 5um; large air volume; low resistance; high dust holding capacity; long service life.
To protect the high-efficiency air filter, the most commonly used method is to select G4 for the efficiency of the primary filter and F7-F9 for the efficiency of the medium-efficiency filter, and the primary filter usually needs to be replaced within 1-3 months or For cleaning, the medium-efficiency filter must be replaced within 3-6 months. As long as the relevant rules are followed, the service life of the high-efficiency filter must be effectively extended .
