Key components include:

Filters: Primary and secondary filters with varying micron ratings.
Pumps: To circulate the oil through the system.
Sensors and Gauges: For monitoring pressure, flow rate, and temperature.
Heating Elements: To reduce oil viscosity if needed.
Control Systems: For automated operation and safety features.
Housings and Connections: Secure containment and integration with machinery.
These components work together to effectively purify the oil.
