WHAT IS A ROTARY SCREW AIR COMPRESSOR AND WHAT ARE ITS BENEFITS?

A rotary screw air compressor is, simply, rotary positive displacement air compressor, capable of high-speed operation over a wide range of operating pressures and flow rates while offering high efficiency. In screw air compressors, there are no valves or other mechanical forces that can cause obstruction during the compression process. This allows a compressor to operate at high speeds while combining a large flow rate while still being compact than other technologies. The main advantage of using a rotary screw air compressor is that it supplies compressed air continuously with minimal fluctuation in delivery pressure and optimises thermal energy management.

Industrial rotary screw air compressors are instrumental in enhancing productivity, efficiency, and operational cost across various industries by delivering reliable and consistent compressed air for a wide range of applications.

Other advantages of using rotary screw air compressors that will help Africa’s industries grow, include:

Convenient, as they deliver air continuously for the required purposes, and safe, as the chances of having an accident are minimal.
Functions at extreme weather conditions as the compressor can work at high temperatures or in low conditions to suit your convenience and at any forms of energy or temperatures levels.
Lowers maintenance costs drastically.
Long-lasting, as they have little or no capacity reduction.
Designed to run tools that generate more power than typical equipment.
Low noise output machine.
Minimum oil-carryovers, as low as 3 ppm in oil lubricated machine.

WHAT IS THE WORKING PRINCIPLE OF ROTARY SCREW AIR COMPRESSOR?

The Rotary Screw air compressor uses a rotary-type positive-displacement mechanism. The screw element consists of two rotors that are similar to a helix, each with a different shape and number of grooves/teeth. Atmospheric air is sucked into this screw element, and as the air progresses along the two interlocking rotors, it gets compressed. The main characteristic of this type of compressor is a male and a female rotor element, which traps the air and compresses it as it passes across the airend.

In an oil-lubricated rotary air compressor, the male rotor is driven by the electric motor or engine, which in turn drives the female rotor and compresses the air due to a reduction in volume.
In an oil-free rotary air compressor the lubricating media is a special coating on the rotors instead of oil which ensures 0 oil carryover to the outlet.

The basic principle of a rotary-type compressor is that both the male and female rotors are spinning in opposite directions. The prime mover turns the rotor of the airend in a rotary screw air compressor. This creates a vacuum resulting in surrounding air being driven into the airends through the air filter. As the rotors turn progressively, the air gets trapped in the spaces between the two screws (rotors).

Air is taken from the atmosphere into the rotary screw compressor through the air intake system. It passes through a filter that helps in removing suspended particles from it. The filtered air goes in the airend, is the heart of the screw type compressor. Here, the air is trapped within the spaces between the two rotors with mesh lobes. . As the rotors turn, they progressively compress the trapped pockets of the air, and the compressed air is discharged at the outlet of the airend.

ELGi’s EN & EG series, rotary screw electric air compressors offer best-in-class performance and are engineered for easy maintenance and operation for industries in Africa.
