The purity of the compressed air is highly essential and it is also difficult to achieve. Even a small drop of oil can spoil the quality of the end product. When oil is used for your process, it becomes difficult to maintain the air quality thus increasing the costs. In order to avoid these problems, many industries are now switching to oil free air compressors for their process. Oil free air compressors ensure high quality, pure compressed air as the system does not require any oil for its operation. Oil free compressors use alternative mechanisms like water or Teflon to ensure smooth running. The lubrication of the gears and bearings of the oil free system is present outside of the compressed air chamber and proper sealing can prevent contamination of the compressed air. Thus, oil free systems deliver 100% oil free air compressed air. Cast supplies ELGi designs AB series oil free screw air compressorsfor industries like pharmaceuticals, food and beverage and healthcare where oil and moisture cannot be tolerated.These are sometimes called as dry screw air compressors.

Oil-free compressors eliminate the need for oil changes and related maintenance tasks, reducing operational costs and downtime.
Eco-Friendly
As oil-free compressors eliminate oil consumption and the associated disposal of oil-contaminated condensate, they contribute to a more environmentally friendly operation.Leading oil free compressor manufacturers like ELGi prioritize environmental sustainability by incorporating eco-friendly features into their designs.
Applications of Oil Free Screw Air Compressors
Food and Beverage Industry:
Even the slightest contamination can compromise the quality of food and beverage products, which is why oil-free compressors are essential for air agitation, pneumatic conveying, and packaging in the food and beverage industry.
Pharmaceutical Industry:
Oil-free compressors are necessary for pharmaceutical manufacturing, where sterile conditions are essential for tablet coating, aseptic packaging, and fermentation.
Automotive Painting and Finishing:
Oil-free rotary screw air compressors play a crucial role in automotive painting and finishing processes. They are a preferred choice for these applications as they ensure the delivery of pristine, oil-free compressed air for tasks such as spray painting and powder coating. The absence of oil particles in the compressed air is essential to maintain the high-quality standards required for automotive coatings. Any presence of oil can lead to imperfections in the paint finishes, negatively impacting the overall quality of the surface finishing.
Textile and Apparel Manufacturing:
Oil-free air compressors play a vital role in diverse applications, including air jet looms, spinning machines, and air knives utilized for fabric cleaning. The critical aspect here is to prevent oil contamination, which has the potential to blemish or harm fabrics. Such contamination not only results in quality problems but can also disrupt production schedules, underscoring the significance of oil-free air compressors in ensuring smooth operations within textile manufacturing.
