The inlet filter DS103EA100V/- W and outlet filter are distinguished based on their installation position and function in the system. The following are the main differences between the inlet filter element DS103EA100V/- W and outlet filter elements of the EH oil station main pump:

1. Installation location
-Inlet filter element (DS103EA100V/- W):
-Installed at the inlet of the EH oil station main pump, it is the last filtration device before the oil enters the pump.
-The main function is to protect the main pump, prevent impurities in the oil from entering the pump, and avoid wear on key components such as the impeller and shaft seal of the pump.
-Export filter element:
-Installed at the outlet of the main pump in the EH oil station, it is a filtering device for the oil before it enters the system after being pressurized by the pump.
-The main function is to further purify the oil and ensure that the oil entering the system meets higher cleanliness requirements.

2. Filtering accuracy
-Inlet filter element (DS103EA100V/- W):
-The filtration accuracy is generally around 10-20 microns, which can effectively remove larger particle impurities.
-The main purpose is to protect the main pump and prevent large particles and impurities from entering the pump and causing damage.
-Export filter element:
-The filtering accuracy is usually higher, usually between 5-10 microns or even lower.
-Used to further purify the oil and ensure higher cleanliness of the oil entering the hydraulic system, meeting the strict requirements of the system for oil cleanliness.

3. Pressure and flow rate
-Inlet filter element (DS103EA100V/- W):
-The working pressure is relatively low because the oil has not been pressurized before entering the pump.
-The flow rate is relatively large, and sufficient flow capacity is required to ensure the smooth entry of oil into the pump.
-Export filter element:
-The work pressure is relatively high because the pressure of the oil increases after being pressurized by the pump.
-The flow rate is relatively small, but it requires sufficient strength and stability to withstand high pressure.

4. Functional focus
-Inlet filter element (DS103EA100V/- W):
-Focus on protecting the main pump and preventing impurities from entering the pump and causing wear.
-By filtering out larger particle impurities, the service life of the main pump is extended.
-Export filter element:
-Focus on further purifying the oil to ensure the cleanliness of the oil entering the hydraulic system.
-By filtering out tiny particles and impurities, the reliability of the system is improved and the failure rate of hydraulic components is reduced.

5. Maintenance and replacement
-Inlet filter element (DS103EA100V/- W):
-Due to the filtering of larger particle impurities, the clogging speed of the filter element is relatively slow, and the replacement cycle is relatively long.
-It is generally recommended to check every 6-12 months and decide whether to replace it based on actual usage.
-Export filter element:
-Due to higher filtration accuracy, the clogging speed of the filter element is relatively fast, and the replacement cycle is relatively short.
-It is generally recommended to check every 3-6 months and decide whether to replace it based on actual usage.

6. Application scenarios
-Inlet filter element (DS103EA100V/- W):
-Suitable for the inlet of the EH oil station main pump, it is the last line of defense before the oil enters the pump.
-Suitable for EH oil systems in industrial scenarios such as power plants and steel mills.
-Export filter element:
-Suitable for the outlet of the EH oil station main pump, it is the last purification device before the oil enters the hydraulic system.
-Suitable for hydraulic systems with high requirements for oil cleanliness, such as precision hydraulic equipment, control systems, etc.
