OIL FREE SCREW AIR COMPRESSORS

ELGi’s oil-free screw air compressors comply with class zero oil standards with no breakdowns & workable economics. They are designed & manufactured with our in-house oil-free technology like oil-free airends and unique eta-V rotor design, helping deliver the highest quality air during the manufacturing process.

Oil-free air compressors draw in the outside air through the unloader valve, controlled by the control system. When the valve is open, the compressor pumps air and is active. The oil-free screw air compressors are less expensive, lighter in weight, and produce as much airflow (CFM) & pressure (psi) as many oil-lubricated models.

ELGi’s range of oil-free air compressors offers 100 percent oil-free compressed air solutions. The oil free screw air compressors come with pre coated rotors. They are designed to provide zero risks of contamination and improved energy efficiency. In addition, the oil-free range provides long-term reliability to meet the precise needs of a diverse range of industries that cannot tolerate any scope of contamination. Industries such as pharmaceuticals, food & beverage, semiconductor and electronics manufacturing, automotive, and textiles rely on oil-free air compressors for their operations.

ELECTRIC OIL FREE SCREW AIR COMPRESSORS

AB SERIES OIL FREE SCREW AIR COMPRESSORS

ELGi is one of the few air compressor companies to design and manufacture airends for Oil-free compressor technology. The new AB series air compressors provide disruptive benefits in terms of efficiency, reliability, and air quality resulting in lower life cycle cost and high uptime. In addition, the Class-“0” certified high-quality air makes this compressor ideal for sensitive applications in pharmaceuticals, food, and beverage industries where the presence of oil vapor and moisture is intolerable.

ELECTRIC OIL FREE SCREW AIR COMPRESSOR

45–450 KW

ELGi is amongst the few air compressor manufacturers with an in-house designed and manufactured oil-free airend. ELGi’s oil-free range of air compressors provides class zero oil-free air with leading energy efficiency, reliability, and low operating costs supported by a Best-in-class warranty.

CLASS 0 OIL FREE AIR SOLUTION

Our Oil-free air compressors come with 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. In addition, pipes with special e-coating and optimized rotor clearances provide consistent, clean, oil-free air delivery.

REDUCED COST OF OWNERSHIP

ELGi’s oil-free air technology increases productivity by eliminating energy waste due to pressure drops. In addition, our oil-free air compressors, the AB Series and the OF Series, are designed to enable easy access to components, reducing maintenance time and cost.

DISTINCTIVE DESIGN AND OWNERSHIP OF TECHNOLOGY

ELGi is among the few compressor companies to design and manufacture oil-free airends. ELGi’s air compressors come with our in-house oil-free technology and are engineered to deliver maximum uptime and reliability. In addition, 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

Our airend rotors and housing come coated with PTFE-based food-grade PP coating to resist corrosion and endure high temperatures up to 250 degrees C. This results in optimum long-term performance with no loss in efficiency.

APPLICATIONS OF OIL-FREE AIR COMPRESSORS

PHARMACEUTICAL

Contaminant free air of high quality is of utmost importance for the pharmaceutical industry. ELGi’s Oil-free compressors offer the highest quality clean and compressed air for various processes in the Pharma industry, such as Tablet Coating & Drying, Bottle cleaning, Nitrogen separation, and many more.

TEXTILE

Oil from the air compressors can leave grease stains on fabric, causing it to darken and damage the end product. Therefore, it is recommended to choose oil-free compressed air throughout the production process and reduce the risks of rejections. ELGi’s oil-free screw air compressors are used in jet looms for dry and oil-free compressed air helping with the intermingling of yarn to give it shape, elasticity, and prominence while ensuring the finished fabric’s quality.

FOOD AND BEVERAGE

Quality and health matter the most in the food and beverage industry; therefore, oil-free compressed air becomes pivotal in the operations. Compressed air is used to supply oxygen to bacteria to form citric acid during the fermentation process. The presence of oil during the fermentation can affect the process and contaminate the end product. Oil-free air compressors also find application in food storage. Nitrogen is used to store food in cans. The nitrogen used must be oil-free as it directly contacts the food.

AUTOMOTIVE

Compressed air finds application in various processes in the automotive industry, such as spraying paint on the vehicle, assembling parts, and more. The presence of oil in the air may cause bleeding or prevent adhesion. Therefore the use of oil-free compressed air becomes vital. Oil-free air compressors from ELGi offer reliable, high-quality, contaminant-free compressed air for the automotive industry.
