The strainer is to separate solid impurities from the fluid to improve product purity, purification and gas purification, and it can protect equipment (compressors, pumps, instrumentation, etc).

The strainer is widely used in industrial water treatment, municipal water treatment, crude oil, and even swimming pools, landscape, domestic water processing applications. Precision strainer means to filtered accuracy, generally between the sand filtration (coarse strainer) and ultrafiltration. Under pressure, the raw water through the strainer, the impurities trapped in the strainer wall, the water flow through the strainer, so as to achieve the purpose of filtering.

At present, the strainer manufacturers are small and middle enterprises. The product uses high quality stainless steel, rigid PVC, engineering plastics, glass and other corrosion-resistant materials to do the shell, including high quality stainless steel, built-in media strainer. The built-in strainer PE core, honeycomb core, folded core, sintered titanium tube core, carbon core, the ceramic core, polypropylene fiber strainer. Strainer different strainer effects, and therefore precision strainer to remove suspended solids in water according to the raw water quality, water quality and volume requirements, certain colloidal substances and fine particles, different strainering accuracy. Are currently on the market precision strainer of strainering accuracy range of 0.2-100um.

The strainer is usually installed at the inlet of the hydraulic control valves and other equipment to prevent particulate impurities into the channel, causing blockage, the valve or other device to failure of normal use, mechanical hydraulic control valves and precision easy to plug the product must have filtration equipment.
