Two Stage Air Compressor - Ranging from 60-500 HP

ELGi is one of the very few compressor companies to design and manufacture oil free airends. With in house oil free technology, the compressors are engineered to deliver maximum uptime and reliability. ELGi's unique eta-V rotor design reduces pressure losses and increases stage efficiencies, leading to an optimized compressed air system.

Optimized component layout of the OF series machine provides easy serviceability with reduced service time. Incorporating superior safety norms, the compressors have not only low energy loses and low air outlet temperatures but are also highly reliable and compact. All these advanced features integrated into one simple design that drives maximum reliability and uptime.

WHY ELGi's TWO STAGE AIR COMPRESSOR, OIL FREE SERIES?

Class 0 oil free air
Our Oil Free rotary screw air compressors have consistent oil-free air meeting ISO8573-1 class 0 oil standards. Food grade coating is done where air contacts metal surface inside the compressor ensuring consistent oil-free air without metal debris. Pipes have special e-coating which ensures consistently clean and oil-free air along with optimized rotor clearances which ensures consistent air delivery.

Indigenously designed and manufactured airends
ELGi is one of the very few compressor companies to design and manufacture oil free compressors. With our in-house oil-free technology, the compressors are engineered to deliver maximum uptime and reliability. ELGi’s two stage oil free compressors unique eta-V rotor design reduces pressure losses and increases stage efficiencies, leading to an optimized compressed air system.

ELGi’s proprietary coating on airend for long term reliability
Our airend Rotors and housing are coated with PTFE based food-grade PP coating to resist corrosion and endures high temperatures up to 482 °F. This results in optimum long term performance with no loss in efficiency.

Flexible design allowing for air cooled and water cooled requirements
Our Oil Free screw air compressors carrying Cupronickel coolers with water-in-tube system, specially designed for temperature difference of max. 46.4 °F having least fouling factor in its kind with best thermal efficiency.

Best-in-class warranty
ELGi comes with Uptime Assurance which is all about giving customers peace of mind by offering industry's leading warranty which warrants that it's product and the components for its products will perform the purpose and function for which they are designed and intended for the periods of time indicated when used, serviced and maintained in accordance with ELGi's instruction and specification.

Best-in-class maintenance cost

Air cooled Air compressor Vs Water cooled Air compressor

Air cooled compressors are often chosen for their simplicity, portability, and lower maintenance requirements. They utilize ambient air for cooling, making them easier to install and move around. However, they may be less efficient in extremely high-temperature environments, and their cooling capacity is generally limited compared to water-cooled systems.

Water cooled air compressors, on the other hand, are preferred for applications that demand a greater capacity. They use water as a more efficient heat conductor, which improves heat dissipation. Despite their effective cooling capabilities, they require more sophisticated installation, including additional plumbing and a water supply. Water-cooled compressors may also require more regular maintenance. The decision between the two is based on application requirements, size, and desired level of cooling efficiency.
