The oil free air compressors draw air in a pre-lubricated cylinder for permanent lubrication. This ensures oil-free and identical compressed air quality to that of the intake air. The oil free air compressors are light in weight, less expensive, and produce as much airflow (CFM) & pressure (psi) as many oil-lubricated models.
ELGi offers 100 percent oil-free compressed air solutions through its range of air compressors designed to provide zero contamination risks with improved energy efficiency and long-term reliability. They help meet the precise needs of a diverse range of industries such as pharmaceuticals, food & beverage, electronics, and textiles that can not tolerate any chance of oil contamination in the process.

Oil-Free Air Compressor Applications
Oil-free air compressors have a wide range of applications across several industries where air quality plays a critical role. Industries that require adherence to strict quality standards should consider using oil free compressed air. The quality and purity of compressed air can directly impact the product quality and efficiency of the manufacturing process. Using oil-free compressed air can help avoid any contamination downstream that can potentially damage equipment and cause downtime. Oil-free compressed air is crucial in many industries including:
Food and Beverage: Oil-free compressed air is a critical requirement in the food and beverage industry to ensure product and consumer safety, compliance with food regulations, preventing cross-contamination, and ultimately ensuring equipment reliability in the production process. Many food and beverage companies across ELGi North America trust ELGi’s oil free compressors to provide clean and reliable oil-free compressed air.
Pharmaceutical: Oil-free compressed air is essential in the pharmaceutical industry to ensure product quality, comply regulatory bodies, such as the FDA (Food and Drug Administration), prevent contamination, protect equipment, ensure worker safety, maintain process consistency. ELGi’s OF Series and AB Series oil-free screw compressors are efficiently powering prestigious pharmaceutical companies across the globe.
Electronics: The electronics assembly process often requires a controlled and clean environment to ensure the quality and reliability of electronic components. The use of oil-free air compressors becomes crucial. Oil-free compressed air is essential for maintaining the integrity of electronic components, ensuring product quality, and reducing maintenance efforts, It is a critical factor in achieving the precision and reliability required in the manufacturing processes of electronic devices.
Automotive: The use of oil-free air compressors in the automotive industry is essential in processes where the presence of oil can affect the quality if the final product. In the automotive industry, particularly in the painting and finishing process, oil-free air is necessary to ensure a high-quality finish. Oil particles in compressed air can lead to defects in the paint job, affecting the appearance and durability of the coating. Oil-free compressed air is also a critical requirement to maintain the performance and longevity of tools and equipment and create a clean and safe working environment.
The Food and Beverage, Pharmaceuticals, Electronic, and Automotive industries are just a few industries that require oil-free compressed air. If you application requires oil-free compressed air, ELGi has a compressed air soluition for you. Contact us to determine whether the AB Series or OF Series is a good fit for your facility.
