The Parker 931020Q is a hydraulic oil filter element primarily designed to remove solid particles and colloidal substances from hydraulic systems. It controls the contamination level of the working medium and protects hydraulic components. Suitable for applications in construction machinery, hydraulic power units, power plants, and similar scenarios, it features high-precision filtration and structural safety.

Core Applications and Functions
Impurity Filtration: Removes solid particles and colloidal substances from hydraulic oil, effectively controlling working fluid contamination levels and safeguarding specific components within hydraulic systems (e.g., pumps, valves). 
Application Scenarios: Installed upstream of components requiring protection in medium-pressure pipelines. Widely used in concrete pumps, construction machinery hydraulic filtration, hydraulic station oil filtration, and industrial sectors including power plants and steel mills.
