Which component filters debris before entering the LO system?

Which component filters debris before entering the LO system?

• A. LO strainer
• B. LO unloader
• C. LO cooler
• D. LO pump

Answer: (A)

In a lubrication oil (LO) system, debris must be filtered at the source to protect the pump and bearings. The LO strainer sits on the suction side and traps larger particles, letting clean oil flow into the LO pump and through the rest of the system. The other components have different roles: an LO unloader relieves pressure or unloads the pump, an LO cooler lowers oil temperature, and an LO pump moves the oil through the system. So the LO strainer is the component that filters debris before entering the LO system.
