Understanding Air Requirements for Oil–Air Lubrication Systems

Lubrication systems are essential to equipment reliability, and oil–air lubrication is increasingly adopted for its precision and efficiency. Unlike traditional methods, oil–air lubrication delivers a controlled micro-dose of oil carried by compressed air directly to the friction point, minimizing waste while keeping components clean.

The continuous airflow also removes heat, helping bearings and other critical parts operate at lower temperatures and significantly extending service life.

To perform effectively, oil air lubrication systems require two key air conditions.

First, stable air pressure, typically around 3–4 bar, is essential. In systems with multiple lubrication points or long pipelines, slightly higher pressure may be needed to compensate for pressure loss and ensure uniform oil distribution.

Second, air quality is critical—excess moisture can break down the oil film and cause corrosion of bearings, gears, and other precision components. Modern oil-air lubrication systems address these requirements with integrated air filtration, dewatering, and pressure-regulating units, ensuring clean, dry, and stable air supply.

Once properly set, the system operates automatically, reducing maintenance effort and minimizing downtime caused by lubrication failures.

By delivering lubrication with less oil but greater precision, oil–air lubrication helps industrial equipment run more efficiently, reliably, and sustainably.
