Knowledge Sharing | Hydraulic Filters: Core Components for Stable Hydraulic System Operation

In the maintenance of hydraulic equipment, industry statistics show that over 70% of hydraulic system failures are caused by contaminated hydraulic oil. Solid particles, moisture and air impurities continuously abrade precision components such as pumps, valves and cylinders, leading to sluggish movement, oil leakage and shortened service life of machinery. As the primary purification barrier of hydraulic systems, hydraulic filters trap contaminants and maintain required oil cleanliness.

Wenzhou Jingtong Hydraulic Co., Ltd. (Formerly Wenzhou Jingtong Hydraulic Parts Factory) was founded in 2006 and specializes in R&D and manufacturing of hydraulic filtration products. The company produces a full range of hydraulic filters and hydraulic air breathers. Equipped with complete testing systems, we strictly comply with ISO9001:2008 quality management system standards. Our products serve eight major industries including construction machinery, mining & metallurgy, plastic machinery, marine and offshore engineering.

Filter selection shall consider system pressure, flow rate, target cleanliness level and ambient dust conditions. Suction filters, return line filters and in-line filters are recommended for different working conditions. Regular element replacement and pressure differential monitoring can effectively cut downtime and maintenance costs, and extend machine service life. With a 6,000 m² standard factory building and more than 20 domestic sales outlets, Jingtong Hydraulic provides customized filtration solutions for global customers.
