This manual provides a comprehensive step-by-step guide for replacing lubricating oil in an air compressor. It covers pre-change preparations, detailed oil drainage and refilling procedures, oil filter replacement, safety precautions, and post-replacement inspection steps. Suitable for routine and scheduled maintenance, the guide helps operators perform oil changes correctly, extend equipment life, prevent waste, and ensure safe operation. Recommendations are included for initial oil use and determining optimal oil change intervals through oil analysis.

In many manufacturing enterprises, ‘continuous operation’ is virtually an essential test that equipment must withstand, and vacuum pumps are naturally no exception. Whether in electronic ceramics, lithium batteries, pharmaceutical packaging, or food processing, any downtime of industrial vacuum pumps translates to interrupted production capacity, increased energy consumption, and process rework.

Thanks to their oil-free contamination, high operational efficiency, and strong reliability, oil-free centrifugal air compressors have gained extensive adoption in industries and projects with stringent requirements for air purity and supply stability.

Small textile factories or low-quality processes tend to use ordinary screw compressors with filters, which are less expensive, while high-end fabrics and stable air sources require oil free air compressors.

In order to actively respond to the voice of environmental protection, Elang is accelerating into a new stage of high efficiency, intelligence and green. As an important driving force for change in this field, Elang centrifugal air compressors have made breakthroughs in core technology, energy efficiency level and intelligent application.
