For a new machine, the oil filter element should be replaced after the first 500 hours of operation. Use a specialized wrench to unscrew the oil filter element, and it is advisable to add screw machine oil before installing the new filter element. Seal the filter element with both hands and tighten firmly.
It is recommended to replace the new filter element every 1500-2000 hours. It is advisable to replace the oil filter element when changing the oil, and in harsh environmental conditions, the replacement interval should be shortened.
Using the oil filter element beyond its recommended service life is strictly prohibited. Otherwise, due to severe clogging of the filter element, the pressure difference exceeds the limit that the bypass valve can withstand, causing the bypass valve to automatically open, allowing a large amount of dirt and particles to enter the screw compressor, resulting in serious consequences.
For diesel-driven screw compressors, the replacement of the engine oil filter element and diesel filter element should follow the maintenance requirements of the diesel engine, and the replacement method is similar to that of the screw compressor oil filter element.
