Filter Media: The material used in the filter media, which can vary depending on the application and the required filtration efficiency.

Micron Rating: The size of particles the filter can effectively remove, usually measured in microns.

Flow Rate: The volume of fluid the filter can process within a given time frame, often measured in liters per minute (L/min).

Operating Voltage: The voltage required for the electro-hydraulic system to function effectively, which is crucial for the filter's performance.

Temperature Range: The operational temperature range within which the filter can work effectively, typically specified in degrees Celsius.

Pressure Rating: The maximum pressure the filter can withstand, often measured in bars or pounds per square inch (psi).

Material: The materials used in the construction of the filter element, which can include metals, plastics, or composites.

Size: The physical dimensions of the filter element, including its diameter, length, and any relevant mounting dimensions.

Application: These filter elements are designed for use in trailer electro-hydraulic relief units, which suggests they are tailored for mobile hydraulic systems.

Compatibility: The filter should be compatible with the specific hydraulic fluid used in the system.
