WHY CHOOSE ELGi OIL-FREE SERIES?
1) Class 0 oil-free air
Our two-stage oil-free compressor series has consistent oil-free air meeting ISO8573-1 Class ‘0’ standards. Food grade coating is done on parts where the air contacts the metal surface inside the compressor, ensuring consistent oil-free compressed air without metal debris. Pipes have special e-coating, which ensures consistently clean and oil-free compressed air, along with optimised rotor clearances, which ensure consistent compressed air delivery
2) Indigenously designed and manufactured airends
ELGi is one of the very few air compressor companies to design and manufacture oil-free airends. With our in-house oil-free technology, the Class ‘0’ air 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 optimised compressed air system
3) Airend coating for efficiency and long-term reliability
Our airend rotors and housing are coated with a proprietary coating to resist corrosion and endure high temperatures up to 250-degree C. This result in optimum performance with no loss in efficiency.
4) Flexible design allowing for air-cooled and water-cooled requirements
Our Oil-Free Series have Cupronickel coolers with a water-in-tube system, specially designed for a temperature difference of max. 8 degrees C, having the least fouling factor of its kind with the best thermal efficiency.
5) Best-in-class warranty
ELGi comes with Uptime Assurance which is all about giving customers peace of mind by offering the industry leading warranty which warrants that its product and the components 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 instructions and specifications.
6) Best-in-class maintenance cost
With our Rack and Pinion capacity control system in the Oil-Free Series, there is no maintenance required for over one million cycles. This exceptional durability is further enhanced by the long-life air seals and oil seals, which significantly reduce wear and tear.
7) Advanced Cooling System
The integrated aftercoolers and inter-stage cooling systems enhance thermal efficiency and help maintain consistent performance, thereby protecting internal components and extending the overall lifespan of the compressor. Superior heat dissipation also contributes to energy efficiency and minimises the risk of overheating.
8) Effective Lubrication for Critical Components
The OF Series incorporates a precise and reliable lubrication system that ensures smooth operation of bearings and mechanical parts without contaminating the air. This guarantees low wear and long service intervals while maintaining oil-free compressed air delivery for sensitive applications such as pharmaceuticals, food, and electronics.
9) Efficient Low Pressure System
The OF Series includes a robust low-pressure system that supports auxiliary operations without overloading the primary compression stages. This thoughtful integration allows for optimal compressed air management and energy conservation. A low-pressure air compressor system is ideal for applications that require different air pressure levels within the same facility, offering flexibility and efficiency in a single package.
