What Is an Oil Free Screw Compressor?

An oil free screw compressor is a rotary screw air compressor designed to produce compressed air without oil entering the compression chamber.

Unlike traditional oil-injected screw compressors, oil free screw compressors use water lubrication or dry compression technology to avoid oil contamination, making them suitable for industries where compressed air purity is critical.

Product Types

Geso Oil Free Screw Compressor Solutions

1. Water Lubricated Oil Free Screw Compressor

Water lubricated oil free screw compressor uses water as the sealing, cooling and lubricating medium instead of oil.

The compression process avoids oil contamination while maintaining stable performance and lower operating costs.

Advantages

Oil-free compressed air
Lower maintenance cost
Stable continuous operation
uitable for low and medium pressure applications

Application

Food processing
Pharmaceutical
Medical equipment
Electronics
Textile

2. Dry Oil Free Screw Compressor

Dry oil free screw compressors achieve oil-free compression through specially designed sealing and air-end technology.

They are designed for applications requiring extremely high compressed air purity.

Advantages

Zero oil contamination
High purity compressed air
Suitable for critical production environments

Application

Semiconductor
Pharmaceutical manufacturing
Laboratory
Precision manufacturing

Why Choose Oil Free Screw Compressor?

Oil Free VS Oil

Feature	Oil Free Screw Compressor	Oil Injected Screw Compressor
Oil contamination risk	None	Possible
Air purity	High	Requires filtration
Maintenance	Lower oil-related maintenance	Oil separator/filter replacement
Suitable industries	Medical, Food, Pharma	General industrial

■ High efficiency: The excitation system loss is canceled, which improves the efficiency by 5-12%. High power factor, large torque-to-inertia ratio, reduced stator current and stator resistance loss, and measurable rotor parameters and good control performance. No matter light load or heavy

load, it always maintains high efficiency. Geso adopts permanent magnet motor with national class 1 energy efficiency standard.

■ Not full load, still high efficiency: Permanent magnet motor energy efficiency in full load operation than the conventional asynchronous motor is generally higher than 9%, with the speed down, its energy efficiency basically remains unchanged, while asynchronous motor speed with the reduction of its energy efficiency will be greatly reduced, or even reduced to less than 50%.

■ Stability: Synchronous motors respond quickly and excel in exhaust responsiveness.

Applications of Oil Free Screw Compressor

Medical Industry
