Core Functions and Benefits of the Refcomp 502989 Built-in Oil Filter
1. Precise Filtration of Oil Circuit Impurities
Efficiently filters out metal debris, casting residues, sludge, and carbon deposits generated during compressor operation; prevents impurities from entering bearings, rotors, and slide valves; and guards against wear, jamming, and shaft seizure.
2. Protection of Precision Oil Circuit Components
Intercepts minute particles to protect the oil pump, oil nozzles, oil pressure regulating valve, and bearings; maintains an unobstructed oil flow and stable oil pressure (typically 0.2–0.3 MPa); and prevents oil pressure fluctuations that could trigger unit safety shutdowns.
3. Extended Service Life of Refrigeration Oil
Minimizes the catalytic oxidation and acidic contamination of the refrigeration oil caused by impurities; retards oil degradation; extends oil change intervals (to 2–3 years); and reduces maintenance costs.
4. Integrated Design: Stable and Reliable
Features a built-in design integrated directly into the compressor body, offering a compact structure that is resistant to vibration and leak-proof; ideally suited for compressor operation under high-load conditions and across a wide temperature range.
