How Do Rotary Screw Air Compressors Work?

Rotary screw compressors operate on a principle of positive displacement, utilizing two intermeshing helical rotors within a compression chamber. As ambient air is drawn in through an air filter, it passes through an inlet valve into the compression chamber where the rotating rotors trap and compress the air by reducing the volume of the spaces between their lobes. In oil-lubricated models, oil is injected to lubricate the rotors, cool the compressed air, and seal gaps between the rotors. The air-oil mixture then moves to a separator tank where the oil is extracted and recirculated, and the cooled compressed air is delivered to an air receiver tank or directly to the application, often passing through an aftercooler to reduce temperature and remove moisture. Equipped with advanced control systems, these compressors ensure efficient, reliable, and continuous operation, making them ideal for various industrial applications.

Advantages of Rotary Screw Compressors

Continuous Operation
Rotary screw compressors can operate continuously without the need for frequent shutdowns, making them ideal for demanding industrial applications.

They are highly efficient, providing a consistent compressed air flow with minimal energy loss.

Low Maintenance
With fewer moving parts and robust design, rotary screw compressors require less maintenance compared to other types of compressors.

Quiet Operation
They operate more quietly than reciprocating compressors, making them suitable for use in noise-sensitive environments.

ELGi Electric Screw Air Compressors

The Electric lubricated screw compressor fulfills the requirement of high reliability for small spaces with four models EG, EQ, EV and EN Series.

EG series Compressors are robust and reliable. They are designed to perform at extreme temperatures- from cold to hot and from dry to extremely humid conditions.

The EQ series Electric lubricated screw air compressor offers increased life of consumables by Multi Stage Air Filtration, robust cooling system. Its function in the most demanding and the toughest of conditions. Designed for customer specific application needs, each compressor provides maximum uptime, long consumable life, and minimal maintenance thus providing value for small and medium enterprises (SMEs).

The new EV Series ELGi Electric Lubricated Screw Compressors come with energy efficient eta-V-profile airends , these airends are driven by premium efficiency motors to increase the efficiency of the system and reduce carbon emission. EV series are equipped with 4 stages of air filtration comprising of twin-element air filters.

Lubricated Air Compressor- Maintenance Tips

  • Check the oil level regularly in your compressor’s pump and top it up if necessary. After a few hundred hours of use, change the oil.
  • Inspect for unusual noises or vibrations, if you have an air receiver tank, drain water from the tank.
  • Check for air leaks or use a soapy solution to check connections and seals. To maintain the smooth operation of your compressor, adjust or replace them as needed. Drain condensate from tanks.
  • Inspect the belts and pulleys for wear and tear, looseness, or cracks. To maintain the smooth operation of your compressor, adjust or replace them as needed.
  • Schedule professional maintenance and inspections with a qualified technician regularly.
