As a China Air Filter Element Manufacturer, I have some information to share with you. The quality of the air filter is good, mainly depends on the following three aspects:
(1) waterproof function;
(2) Filtration accuracy;
(3) Air permeability.
Detailed inspection is as follows:
First, the water test. Place the air filter on the ground or on the table and sprinkle some water on the filter paper;
(1) If the filter paper seeps out within 5 minutes, it is an air filter made of cotton pulp paper (residual filter paper);
(2) If the filter paper is water for 2-5 hours, it is made of low grade wood pulp paper, which can be used, but it will reduce the gas production power of the air compressor (more power consumption and more gas production) due to the primary effect filter;
(3) If 12-15 seeps, it is attributed to the medium efficiency filter;
(4) If there is no water seepage in 24 hours, it is a high efficiency filter.
HEPA Filter with Partition
At present, there are many types of HEPA Filter with Partition produced and sold in the filter market, and the number of brands will be more. Therefore, when making choices, do not blindly choose, have an understanding of the air filter manufacturers. At the same time, we should also have a grasp of our own needs, because we can choose the products according to our own needs to ensure that the selected products can meet their own needs.
For consumers who use filters, the overall choice is relatively simple when making a purchase. When you understand the specific principles, you should have an understanding of the import and export path. In principle, the inlet and outlet diameter of the air filter should not be smaller than the matching inlet diameter of the pump. If conditions permit, it should be consistent. You should also know the corresponding nominal pressure, and when you understand the parameters, you should determine the specific pressure level of the air filter in strict accordance with the highest pressure that may occur in the filter line. At the same time, there should be some understanding of the number of holes. Usually, the impurity particles that need to be intercepted are mainly considered. In this case, understand the specific media flow process. Helps the use of related equipment. And know the specific mesh specifications, the specific particle specifications can be queried on the website.
Of course, it is very important to understand the specific filter materials. When selecting a specific material, it should be the same material as the process pipe to which it is connected. For different service conditions, consider selecting a material pipe with better quality and higher precision. When calculating the filter resistance loss, it is generally necessary to know the specific rated flow rate, and the corresponding pressure loss is about one Pa. Finally, when choosing a filter factory, consumers should also have a mastery of the specific production process.
For a company, its own production process is different, then the corresponding product quality will be different. The better the process, the better the quality of the products produced. Therefore, when understanding the filter factory and the selection principle, for consumers, it should be comprehensively considered. Only in this way can we ensure that we purchase better filters to meet our own needs.Our company has PES Filter Cartridges, welcome to come to us.
