ELGi Oil free Technology

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 losses 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.

Consistent oil-free air meeting ISO8573-1 class 0 oil standards.

Consistent Air Quality Low life cycle cost- High energy efficiency design delivering maximum UPTIME and lower cost of ownership

Efficiency/Cost of Ownership

• Operates on low pressure cooling-water head Reduced power consumption of feed water pumps 

• Lower temperature differential of cooling water Power saving by reduced cooling water pump sizing 

• Optimized airend design Deliver best efficiency of its class at different pressures and quickerreturn on investment 

• The OF series compressor package ensures that cooling water in-out temperature differential is only 8'C compared to other conventional systems of 14 C Ensures lower thermal stress to the system,better fouling factor and lower cost of ownership 

• Food grade coating is done where air contacts metal surface inside the compressor Ensures consistent oil-free air without metal debris 

• Pipes have special e-coating Ensures consistently clean and oil-free air 

• Optimized rotor clearances Ensures consistent air delivery
