Oil free compressors draw air within a cylinder which is pre-lubricated for permanent lubrication which helps produce compressed air of a quality that is identical to the intake air, which helps the air to remain oil free. This kind of air compressors are less expensive, lighter in weight and produce as much airflow (CFM) & pressure (psi) as many of the oil lubricated models.
ELGi’s range of oil free air compressors offers 100 per cent oil free compressed air solutions which are designed to provide zero risks of contamination with improved energy efficiency and long term reliability to meet the precise needs of a diverse range of industries such as pharmaceuticals, food & beverage, electronics and textiles where cannot tolerate any chance of oil contamination in their processes.
Class 0 oil free air solution
ELGi’s oil free air compressors provide consistent oil free air compressed that meets the ISO8573-1 class 0 oil standards. The part where the air comes in direct contact with metal surface inside the compressor is coated with food-grade material, ensuring consistent oil free air without metal debris. Our pipes have special e-coating which ensures consistently clean and oil free air along with optimized rotor clearances which ensures consistent air delivery.
Reduced cost of ownership
ELGi’s oil free air technology helps to optimize the productivity of your operations by eliminating the energy wasted during pressure drops. Apart from reducing operating costs, our compressors are also designed to easy maintenance by providing clear access to air components.
Distinctive design and ownership of technology
ELGi is among the very few air compressor companies to design and manufacture oil free airends. With our 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.
Highest efficiency and reliability
ELGi’s airend rotors and housing are coated with PTFE based food-grade PP coating to resist corrosion and endures high temperatures up to 250°C. This results in optimum long term performance with no loss in efficiency.
