Why do air compressors at this factory last 5 years longer than similar equipment?

Two factories using the same brand and model of screw air compressors experienced a five-year gap in equipment lifespan. Factory A's equipment began frequent malfunctions after eight years of operation, while Factory B's equipment remained stable after 13 years. The core difference lay in routine maintenance. Factory A only repaired equipment after failures, replaced filters and lubricants past their recommended intervals, and neglected timely repairs for pipeline leaks. Factory B, however, adhered to standardized daily maintenance: recording operational data daily, replacing original manufacturer oil every 2,000 hours, changing air filters every 1,500 hours, and conducting monthly leak detection. According to Factory B's manager, over 13 years, the average annual repair cost was only 3,000 yuan, while Factory A's later-stage average annual repair cost exceeded 30,000 yuan. Industry data indicates that air compressors with standardized daily maintenance can extend their lifespan by 30%-50% and reduce overall operating costs by 40%.
