Class 0 Oil free Air Compressors

Oil free air compressors draw in the outside air through the unloader valve, controlled by the control system.Oil-free screw air compressors work by drawing in outside air through the unloader valve, which is controlled by the control system. When the valve is open, the compressor pumps air and is active.

This type of compressor is less expensive and lighter in weight than many oil-lubricated models, while still producing the same airflow (CFM) and pressure (psi). ELGi oil free air compressors range offers 100 percent oil-free compressed air. The oil free screw air compressors come with pre-coated rotors. They offer zero risk 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. People also refer oil-free air compressors as dry screw air compressors/oilless air compressors as these do not use oil as a lubricating media.

ELGi’s oil free screw 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 optimised 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.

PHARMACEUTICAL

Compressed Air in pharmaceutical industry plays a pivotal role in ensuring product quality and safety. 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 air compressors for textile industry are used in jet looms for dry and oilless 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; the role of an air compressor for food processing becomes pivotal, especially with oil-free compressed air. 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. Oilless compressors also find application in food storage. Nitrogen is used to store food in cans. The nitrogen, generated using compressed air, must be oil-free as it comes in direct contact with 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.

These compressors offer high uptime and contribute to creating high-quality, defect-free electronic products as there are no traces of oil. As a result, oil-free air compressors for electronics industry meet the high quality, clean air criteria.

ADVANTAGES OF OIL FREE COMPRESSORS

Elimination of Oil Contamination: Oil free compressors, as the name suggests, do not require oil lubrication for operation. This means no risk of oil contaminating the compressed air output. Oil-free compressors are essential to maintain product purity and safety in applications where air quality is critical, such as food and beverage processing, pharmaceutical manufacturing, electronics, and medical industries.

Energy Efficiency: Oil-free air compressors have an efficient package design, from rotors coated with a proprietary layer for lubrication to a robust cooling system. The coated rotors ensure optimal heat dissipation, resulting in improved energy efficiency. Additionally, the cooling system utilises minimal electrical energy to ensure that the overall package offers high system efficiency.

Reduced Maintenance Costs: Oil-free compressors do not require frequent oil changes or oil filter replacements. This leads to reduced maintenance requirements, lower service costs, and increased uptime for critical operations. Additionally, the absence of oil also simplifies maintenance procedures, saving valuable time and resources.

Enhanced Reliability: The elimination of oil in the compression process reduces the risk of mechanical failures and breakdowns associated with oil contamination. This leads to improved compressor reliability and longer service life, providing a more stable and consistent source of compressed air for industrial processes. ELGi Oil free compressors offer a compelling solution for reducing emissions in industrial operations. By eliminating the release of hydrocarbons, VOCs, and other pollutants associated with traditional oil lubricated compressors, they directly contribute to lowering greenhouse gas emissions.
