Old Colombian customers, customers are mainly maintenance air compressor OEM customers. At the end of each year, the customer will purchase a batch of oil separator filter as stock, and the customer will send us some  separator filter element models 250034-114, 250034-112, 4930152101, SB521=4930152131, AA096212=LB962/2, 6221372850, 02250100-755/02250100-756, 02250215-621, 02250160-774. Customers have very high requirements for oil and gas separator  filter elements. When we first produced products for customers, we customized samples for customers according to the customer's flow rate, filter area and filter element model. The terminal receives the sample oil test. 

If the customer accepts the batch order through the test, and the test fails, we need to re-customize the production to the customer according to the customer's data. The oil and gas separator  filter elements we make for our customers are all produced according to the folded production process and are made of imported glass fiber. The folded oil and gas separation filter element we made can increase the dirt holding area of the filter element and prolong the service life of the filter element. We produce separator filter elements, using imported glass fiber, which can mainly ensure the filtration accuracy of the filter element. The service life of our separator  filter element is generally 6000-8000 hours, which can reach the service life of the original filter element. Therefore, every year, customers always purchase our compressor oil and gas separator filter products, and the air compressor OEMs also recognize our product quality and our brand.
