What are Oil Lubricated Air Compressors and how do they work?

Oil-lubricated air compressors play a pivotal role in numerous industries and settings. Their robust design and reliable performance make them indispensable for applications such as manufacturing, construction, automotive repair, and more. In industry,  the power pneumatic tools, machinery, and processes, ensuring seamless operations. The dependable output of these compressors makes them the preferred choice for critical applications that demand consistent and high-quality compressed air.

Oil-lubricated air compressors operate by utilizing mechanical energy to compress air. They draw in atmospheric air, which is then compressed through a series of rotors  or vanes. The inclusion of oil within the system serves dual purposes: it lubricates moving components for smooth operation and provides a seal between compression stages. This results in efficient compression and higher air output. The compressed air is subsequently cooled and filtered to remove any residual oil, ensuring clean and reliable output for various industrial applications.

Rotary Screw vs Rotary Vane Compressors 

While both rotary screw and rotary vane compressors utilize oil for lubrication, their mechanisms and operational characteristics differ. Rotary screw air compressors are a subtype of oil-lubricated air compressors known for their efficiency and reliability. They consist of key components such as rotors, air inlet, discharge valve, and oil separator. These compressors operate by trapping air between the rotors and gradually reducing their volume, resulting in compressed air output. The oil-lubricated system ensures smooth rotation and sealing of the rotors, contributing to efficient compression.

In contrast to rotary screw compressors, rotary vane compressors employ a different mechanism for air compression. These compressors feature a rotor with vanes that are free to slide in and out of their slots as the rotor turns. This movement creates varying chamber volumes, leading to air compression. The vanes are typically held in contact with the inner wall of the compressor housing by centrifugal force and oil lubrication. Our rotary vane compressors offer a simpler design with fewer moving parts, making them relatively compact and easy to maintain. The sliding vane action can provide smooth and pulsation-free compressed air, making them suitable for applications where consistent pressure is crucial.


Maintenance of Oil-Lubricated Air Compressors for Longevity and Optimal Performance


Maintaining your oil-lubricated air compressor to ensure its longevity and peak performance requires consistent attention. Take proactive steps to keep it in optimal condition, allowing it to perform efficiently and reliably throughout its operational life.

Regularly Check and Change Oil Levels and Quality

A fundamental maintenance task involves routinely checking the oil levels and quality within your compressor. Follow the manufacturer's recommendations for oil change intervals, as different systems may have varying requirements. Regular oil changes are essential to guarantee proper lubrication of moving parts, preventing excessive wear and ensuring smooth operation. By staying diligent in monitoring and replacing the oil, you contribute to the overall health of your compressor.

Maintain a Clean Environment

Maintaining cleanliness in and around your compressor is crucial for its longevity. Dust and debris can accumulate over time, obstructing airflow and potentially causing overheating. Regularly clean the compressor and its surroundings to prevent such buildup. This simple yet effective practice helps maintain optimal operating temperatures and prevents the system from working harder than necessary.

Inspect and Replace Filters, Belts, and Wearable Components

Scheduled inspections of filters, belts, and other wearable components are essential to prevent performance degradation. Filters play a crucial role in keeping the air intake clean and free from contaminants. Inspect them regularly and replace them as needed to maintain proper airflow and system efficiency. Similarly, check belts for signs of wear and tension, ensuring they are properly aligned and functioning. Addressing these components promptly helps avoid unnecessary strain on the compressor and extends its operational life.

Monitor for Unusual Sounds and Vibrations

A vigilant ear can often detect potential issues before they escalate. Regularly listen for unusual sounds or vibrations while your compressor is in operation. These can indicate misalignments, loose components, or impending mechanical problems. Addressing such concerns promptly through maintenance or repairs can prevent further damage and downtime.
