ZU-A QU-A WU-A XU-A return line filter series
The ZU-A QU-A WU-A XU-A return line filter series is a product function
The ZU-A QU-A WU-A XU-A return line filter series is a filtering device designed specifically for hydraulic systems. Its main function is to filter out metal powder generated by various component wear and rubber impurities caused by seal wear in the oil, ensuring the cleanliness of the oil, thereby extending the service life of the hydraulic system and improving its working performance.

The ZU-A QU-A WU-A XU-A return line filter series is a product feature
1. Efficient filtration: This filter adopts a new type of chemical fiber filtration material, which has the advantages of high filtration accuracy, large oil flow capacity, low original pressure loss, and large pollutant absorption. Its filtration accuracy can reach 1-30 μ m. Filter ratio β 3. 5, 10, 20>100, filtration efficiency n ≥ 99%, in compliance with ISO standards.
2. Intelligent design: A filter clogging differential pressure transmitter is installed on the top cover of the filter. When the filter is clogged and the pressure difference at the inlet and outlet reaches 0.35MPa, the transmitter will send a signal to remind users to clean or replace the filter in a timely manner. If the fault cannot be immediately resolved after the transmitter alarms, and the pressure difference rises to 0.4MPa, the bypass valve will open on its own and open another oil circuit to avoid damaging the filter and ensure the normal operation of the system.
3. Easy installation: The filter can be directly installed in the return oil pipeline of the hydraulic system, using threaded and flange connections, making installation simple and replacing the filter element convenient.
4. Strong durability: The filter is made of stainless steel material, which has good corrosion resistance and pressure resistance, and can operate stably in various harsh environments.
