Elgi’s oil free screw air compressors are one among the major outcomes of Elgi’s expertise in manufacturing and marketing of air compressors worldwide for the past 50 years. Oil free compressors are backed by emerging technology that conserves natural resources and environment from pollution.They produce consistently high quality and environmental friendly compressed air.
Oil free compressors are air compressors that do not use oil in the chamber during compression process. This results in a 100% oil-free air supply, which is preferred for applications where air purity is critical. The absence of oil in compressed air eliminates the risk of oil carryover, which can harm workers, equipment, and the environment. Oil free compressors are used in various industries, including food and beverages, electronics, pharmaceuticals, and oil and gas. They are designed with advanced technologies, resulting in higher energy efficiency.
Why are Oil free compressors preferred over oil lubricated compressors?
100% oil-free air
Oil free compressors produce 100% oil-free air, essential for applications where air purity is critical. This is of the utmost importance in applications where compressed air directly interacts with the final product or is utilized in sensitive processes such as pharmaceuticals, food and beverage production, and electronics manufacturing.
Lower maintenance costs
Oil free compressors require less maintenance than oil-lubricated compressors, as there is no oil change or filter and oil separator maintenance. They typically have better air compression ratios and consume less energy during operation.
Quieter operation
Oil free compressors are quieter than oil-lubricated compressors, making them a good choice for applications where noise is a concern.
