How Much Compressed Air Does an Oil-Air Lubrication System Consume?

Release time:

2022-12-23

The compressed air consumption of an oil-air lubrication system depends on several operating factors, including:

Bearing size
Bearing housing sealing design
Required cooling and sealing effect of the compressed air

In most industrial applications, the compressed air consumption is approximately:

1.5 Nm³/h per lubrication point

This relatively low air consumption is one of the key efficiency advantages of oil-air lubrication systems.

Much Lower Air Consumption Than Oil Mist Lubrication

Compared with traditional oil mist lubrication systems, oil-air lubrication requires significantly less compressed air.

Typical oil mist lubrication systems may consume approximately:

6–63 m³/h of oil mist or compressed air

This means oil-air lubrication can achieve effective lubrication and cooling with only a fraction of the air consumption.

Why Lower Air Consumption Matters

Reduced compressed air usage provides several practical benefits:

Lower energy consumption
Reduced operating costs
Less load on the plant air compressor system
Improved system efficiency

Since compressed air generation is one of the major energy costs in many industrial plants, lower air consumption can create noticeable long-term savings.

Compressed Air Still Provides Excellent Cooling and Protection

Even with relatively low air consumption, oil-air lubrication systems still provide excellent performance.

The compressed air helps:

Transport lubricant accurately to the lubrication point
Remove heat from bearings and friction surfaces
Maintain positive pressure inside bearing housings
Prevent contamination from water, dust, and scale

This combination of lubrication, cooling, and sealing protection is one of the reasons oil-air lubrication performs so well in harsh industrial environments.

Efficient Lubrication with Lower Energy Demand

Oil-air lubrication systems are designed to deliver:

Precise lubrication
Minimal lubricant waste
Lower compressed air consumption
Stable long-term operation

For industries seeking energy-efficient and reliable lubrication solutions, oil-air lubrication offers an excellent balance between performance and operating cost.
