Quality filter
First, Mrefilter has been using high-quality raw materials, filter materials, steel plates and glue are from famous manufacturers.
1, filter paper: high-quality filter paper micropores in 0.04-0.08mm, the filter paper is arranged orderly and firm, no deformation after oil absorption, high filtration efficiency, strong dust storage capacity, the fold number and fold width of the filter paper are produced in strict accordance with the standard, to ensure the effective filter area and service life of the filter.
2, the center pipe: the selection of high-quality steel, not easy to rust electrolytic plate processing, the filter center pipe on the mesh opening size is moderate, low oil resistance, high compressive strength.
3, glue: the use of imported special filter glue, reliable bonding, no leakage, no degumming.
4, sealing ring: the use of high-quality oil-resistant rubber parts, good sealing performance, reliable use.
Second, good production testing equipment
The company has a modern production line, as well as a variety of professional filter testing equipment. Before the filter leaves the factory, each product is tested for a high pressure seal, and only qualified products can enter the market.
Poor quality filter
1, the filter paper of the inferior filter is poor, the filtration efficiency is low, and the dust storage capacity is poor.
2, the fold number and fold width of filter paper are far below the standard, the effective filter area is not enough, and the life is low. The end and end of the filter element of some manufacturers are folded together with staples, which causes the interface part to pass through and can not filter.
3. The backflow check valve of the inferior filter is not sealed, or even has no backflow check valve.
4, between the poor quality filter cover and the filter element, a small amount of poor adhesive bonding, easy to cause filtration leakage.
5, the center pipe recycling iron sheet coil, easy processing, can not withstand normal oil pressure and deformation.
6, the sealing material of the inferior filter is poor and easy to deform.
