If the oil temperature drops below 40°C or exceeds 90°C, the oil’s quality can deteriorate, leading to potential damage and reduced compressor life. When the oil temperature is too low (below 40°C), the oil becomes too viscous, causing increased friction within the compressor.
[pdf] FS Synthetic Rotary Screw Air Compressor Oil ISO 46 is a full-synthetic, non-detergent compressor oil formulated to protect rotary screw air compressors against wear and carbon/varnish buildup. Typical service life is 6,000-8,000 hours in normal service.
[pdf] The reasons for the high exhaust temperature of screw air compressors : 1. High return air temperature; 2. The motor has a large heating capacity; 3. High compression ratio; 4. High condensation pressure; 5. Improper selection of refrigerant.
