Oil-free compressors draw air within a cylinder which is pre-lubricated for permanent lubrication so as it produces identical compressed air quality to that of the intake air which helps the air remain oil-free. They are less expensive, lighter in weight and produce as much air flow (CFM) & pressure (psi) as many oil lubricated models.
ELGi’s range of oil-free air compressors offers 100 percent oil-free compressed air solutions which are designed to provide zero risk 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.
Our Oil-free air compressors comes with a 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.
ELGi’s oil-free air technology optimize productivity in your operation by eliminating the waste of energy in pressure drops. We have also designed our oil-free technology to make easy maintenance over reduced operating cost by providing clear access to air components.
ELGi is among the very few 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.
Our airend rotors and housing are coated with PTFE based food-grade PP coating to resist corrosion and endures high temperatures up to 250 degree C. This results in optimum long term performance with no loss in efficiency.
