Oil-free screw air compressors use an unloader valve that is operated by a control system to bring in outside air. The compressor operates and pumps in air when the valve is open. The oil-free compressors are less expensive, lighter in weight and produce airflow (CFM) & pressure (psi) as much as that of many oil-lubricated models.
100% oil-free compressed air solutions are available with the oil-free air compressors range from ELGi. The oil free screw air compressors come with pre coated rotors. They are made to offer increased energy efficiency and zero chance of contamination. The oil-free range additionally offers long-term dependability to satisfy the specific requirements of a variety of industries that cannot accept any degree of contamination. Oil-free air compressors are essential to the operations of sectors like medicines, food and beverage, semiconductors and electronics production, automotive, and textiles.
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.
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.
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.
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.
