Many friends use filter elements in their equipment, but when purchasing, they found that the prices of filter elements on the market are very different. If they sell cheap ones, they are afraid of poor quality. If they buy expensive ones, they think they have been pitted. Today, Lvda filter elements are taught here. Give you a few ways to quickly identify the quality of the filter element.
1. Look at the thickness of the filter element skeleton
Generally, the thickness of the inner and outer skeleton of a good quality filter element is between 0.8mm-1.5mm, but some businesses reduce the skeleton to 0.3mm-0.5mm in order to reduce the layer, there is no difference in appearance, but it seriously affects the pressure resistance of the filter element. .
2. look at the filter material
The main filter material of the air filter element is filter paper. At present, the filter paper of the filter element mainly adopts domestic paper and imported paper. Both domestic and imported paper have good filtering performance. The inferior filter paper used in the counterfeit filter element cannot prevent dust from entering the engine, thereby affecting the engine. normal work. Generally, the color of the filter paper of the genuine filter element is uniform, and the paper surface is relatively flat; while the filter paper of the inferior filter element is not uniform in color, the paper surface is hairy, and the texture is very poor.
3. Look at the colloid of the filter element
At present, the structure of the filter element is generally composed of filter paper and rubber bonding, and the colloid of the true and false filter element is also different. The rubber of the genuine filter element has better texture and elasticity, while the rubber of the counterfeit filter element is soft and the texture is poor. The easier way to identify is to fold the air filter in half. After loosening, the genuine filter will quickly return to its original state, while the counterfeit filter does not adhere well to the filter paper due to the rubber texture, and the middle of the fold is obvious.
4. look at the depth of the filter paper and the number of folds.
If the filter paper is deep and the number of folds of the filter paper is large, it means that the filter area of the air filter is large, the filter area of the air filter is large, and the air permeability will be better.
