When it comes to air filter cotton, don’t you know that everyone knows it? This is a filtering medium, through which the air can be used to filter(Meltblown BFE On Sales) and purify pollutant gases, dust particles and exhaust gas contained in the air. So how to choose and replace the air filter cotton? The following Hualei Industry will analyze it for everyone. If you want to know, you can take a look!

1. Grasp the main influencing factors for selection, such as high-temperature gas, flammable dust, etc.;

2. The filtering performance of the filter cotton(Non-Woven Mask Materials Wholesale) should meet the conditions and special requirements in the production process;

3. Gas temperature: The temperature of dusty gas is a very important factor. Generally, the gas below 130℃ is called normal temperature gas, and the gas above 130℃ is called high temperature gas. Therefore, the selection of filter material can also be divided into For these two categories, that is, normal temperature filter material and high temperature filter material;

4. Humidity of the gas: dust-containing gas can be divided into three categories according to its relative humidity. When the relative humidity is below 30%, it is dry gas, when the relative humidity is between 30% and 80%, it is the general state, and when the relative humidity is above 80% It is a high-humidity gas. For high-humidity gas, when the gas is in a high temperature state, condensation will occur when the gas is cooled, which will cause the surface of the filter bag to become fouled and clogged, and it is also easy to corrode the material. This is why we need to be extra when choosing Attention;

5. Choose a filter material with a longer service life as much as possible, which can not only save operating costs, but also meet the emission requirements;

6. Price comparison, beware of some unscrupulous merchants who use price concessions to sell some inferior products. When choosing, shop around and don't be greedy for small and cheap products.
