In the process of operation, the carbon filter cartridge machine has a structure in which the outer layer fiber is thick, the inner layer fiber is thin, the outer layer is loose, and the inner layer is tight and the gradient diameter is gradually tight. The unique gradient deep filtration of the carbon filter cartridge machine forms a three-dimensional filter residue effect, featuring high porosity, high rejection rate, large dirt holding capacity, large flow rate and low pressure drop.
How do customers buy carbon filter cartridge machines?
1. Look at the gel of the filter
At present, the structure of the filter element is generally composed of filter paper and rubber, and the gel of the true and false filter element is also different. The high-quality filter has a good rubber texture and elasticity, while the counterfeit filter rubber is soft and has a poor texture. The easier way to distinguish is to fold the air filter in half. After the loosening, the high-quality filter element will quickly return to its original shape, and the inferior filter element will not bond well with the filter paper due to the rubber texture problem, and the middle mark of the folded half is obvious.
2. Look at the thickness of the filter skeleton
The thickness of the inner and outer skeleton of the filter with good quality is generally between 0.8mm and 1.5mm, but some merchants have reduced the skeleton to 0.3mm-0.5mm in order to reduce the thickness of the layer. There is no difference in appearance, but it seriously affects the compressive capacity of the filter. .
3. Look at the filter material
The main filter material of air activated carbon filter equipment is filter paper. At present, filter paper mainly uses domestic paper and imported paper. Both domestic and imported paper have good filtering performance, and the inferior filter paper used in counterfeit filter can not prevent dust from entering the engine. Affect the normal operation of the engine. Generally, the filter paper of the original filter has the same color, and the paper surface is relatively flat; while the inferior filter paper color is not uniform, the paper surface is hairy, and the texture is very poor.www.wxajmsfiltermachinery.com
