brief introduction
This filter is suitable for precision filtration of hydraulic system return oil, filtering out metal particles and rubber impurities in seals caused by component wear in the system, and keeping the oil flowing back to the tank clean.
The filter is equipped with a transmitter, bypass valve, and liquid flow diffuser. Its main performance characteristics include:
The filter is directly installed on the fuel tank cover plate, and the simplified body extends into the oil tank. The oil inlet is equipped with threaded and flanged connections, which are connected to the return oil pipeline. The pipeline is simple and easy to install.
2. The filter inlet is equipped with a filter blockage indicator. By observing the indicator gauge of the indicator, the blockage of the filter can be monitored at any time. When the inlet pressure reaches 0.35MPa, the transmitter will send a signal, and the machine should be stopped immediately to replace the core reducer.
3. The design adopts a direct return oil filter, which can be replaced by simply unscrewing the upper cover or refilling the fuel tank. There are two M18x1.5 oil ports on the side of the filter head, which can be used to install a transmitter or filter a small amount of oil returning to the oil tank in the system, making it very convenient to replace the filter element and add oil to the tank.
When the filter element is clogged and the transmitter alarms, if the fault cannot be immediately resolved. When the oil inlet pressure rises to 0.4MPa, the bypass shallow located at the lower part of the filter element will automatically open another oil circuit to avoid damage to the shallow valve and ensure the normal operation of the system.
5. The wave core adopts a new type of synthetic fiber filter material. It has the advantages of high filtration accuracy, large oil flow capacity, low pressure loss, and large pollutant absorption capacity.

FAQ
1. Question: What are the common specifications for the filtration accuracy of Rfa hydraulic filters?
-Answer: Common filtration accuracies include 3 μ m, 5 μ m, 10 μ m, 20 μ m, 30 μ m, 40 μ m, etc. Suitable precision filters can be selected based on the cleanliness requirements of the hydraulic system. For systems with high precision component protection requirements, 3 μ m or 5 μ m precision is often chosen.
2. Question: How to maintain the Rfa hydraulic filter?
-Answer: Regularly check the pressure difference of the filter, and replace the filter element in a timely manner when the pressure difference reaches the specified replacement value. At the same time, it is necessary to keep the filter housing clean, avoid external impurities from contaminating, regularly clean the environment around the filter, and prevent dust and debris from entering the system.
3. Question: What should be paid attention to when installing the Rfa hydraulic filter?
-Answer: It is necessary to pay attention to the correct installation direction, strictly follow the product label for installation, and ensure that the oil flow direction is consistent with the direction indicated by the filter arrow. In addition, it is necessary to ensure that the filter is tightly connected to the pipeline to prevent leakage, and conduct a sealing check after installation.
