WHY ELGi's EG Series Screw Air Compressor?

Highly Efficient Airend - Superior Energy Efficiency
At the heart of ELGi's EG Series oil-lubricated screw air compressor lies a unique air end equipped with proprietary η-V profile rotors featuring a 4/5 lobe combination. ELGi’s industrial compressor’s air ends operate at low speeds, maximizing energy efficiency. The EG Series air ends come with a life time warranty. ELGi’s life time air end warranty extends to the entire range of EG Series air compressors, ranging from 15 HP to 300 HP.

Best-in-class Maintenance and Operation Cost
The EG Series screw air compressor comes with ELGi's next-generation technology of oil-injected screw rotors, designed for easy access, with a hinged panel design, stainless control lines, and O-ring flanged faces that eliminate leaks. A filtered cabinet extends the life of components. As a result, they provide high-quality compressed air even in extreme environmental conditions and offer long and trouble-free life with low operation costs. The EG Series industrial compressor’s package is designed to ensure ease of maintenance saving you money on your routine service.

Advanced Package Design - Functional and Aesthetic
Our package is configured with subsystems designed to minimize energy losses, making it a highly energy-efficient solution. In addition, it offers ease of service, and maintains low noise levels, ensuring smooth operations.

Reliable and Efficient Motels
The TEFC severe duty motors in the ELGi's EG air compressors are built with a larger core and increased windings, offering reliability and efficiency. Their direct coupling with the air end enhances energy efficiency, while high ambient ratings make them a reliable choice for all industrial applications.

Lowest Oil Carryover in the Industry (< 1ppm)
ELGi has developed a unique OSBIC process (Oil Separation by Impact and Centrifugal action) to separate air and oil with minimum pressure drop. This process involves removing oil in three stages, delivering consistent low oil carryover in the compressed air, reducing the oil discharged into the environment. This efficient method also increases the life of the air-oil separation filter.

Efficient Cooling System - Large Cooler and Optimized Fan
The oversized and bolted cooler design eliminates thermal stresses, extends the compressor's life, lowers power consumption, and maintains low discharged compressed air temperatures, reducing the load on downstream equipment.

Best-in-Class Warranty Program
ELGi offers a best-in-class warranty on its products and components, ensuring they provide complete peace of mind. The EG Series rotary screw air compressor comes with a lifetime air end warranty and a five-year package warranty, providing customers with best-in-class compressed air products and industry-leading warranty coverage.

Reliability Under Extreme Conditions - Robust and Reliable
The EG Series industrial air compressors are designed to perform in extreme conditions, from cold to hot and from dry to highly humid environments, with ambient temperatures reaching up to 115°F. Optional outdoor modifications and low ambient designs are also available to ensure maximum running time throughout the year.

Optional Variable Speed Drives for Energy Efficiency
Maximize energy savings with the optional Variable Frequency Drives (VFD). ELGi’s integrated VFD matches the compressor output with the demand by varying the motor speed. This results in reduced power consumption following the reduced demand, thus eliminating the frequent load-unload cycle, and offering an energy-efficient solution with low operating speed, low maintenance and low sound level.

Operating Data and Safety Measures
The EG industrial air compressors are equipped with high-pressure trips, high-temperature trips, pressure relief valves, low-voltage trips, single-phase preventers, and reverse rotation prevention mechanisms, to ensure the highest level of safety.
