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.

Applications

Oil free air is required where there is absolute intolerance

of oil vapour presence in the entire manufacturing process

With Rack and Pinion capacity control system, there is no

maintenance for over one million cycles » lower cost of

ownership

Without two-step control With rack and pinion control

Gives an edge to operate numerous cycles in a minute

with reduction in pressure band. This saves energy and

maintains pressure discharge.

Efficiency/Cost of Ownership

Low life cycle cost- High energy efficiency design delivering maximum UPTIME

and lower 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 

quicker return on investment

Every component in ELGi OF series starting from design, manufacturing till quality

testing embody the philosophy of UPTIME ASSURANCE.

The materials used ensure long life, reliability and ruggedness under wide ambient 

conditions to provide you with oil-free air for uninterrupted and seamless 

productivity.
