Oil-lubricated air compressors, compress atmospheric air and store it in an air receiver tank. The lubricating media in the case of oil-lubricated air compressors is oil. Oil offers efficient heat dissipation and frictionless operation for the rotors or the pistons. With ELGi’s lubricated or oil-injected air compressors, you can keep your production process running smoothly with maximum efficiency. They offer high uptime and ensure you get consistent airflow at a low maintenance cost.

OIL LUBRICATED VS OIL FREE COMPRESSORS
Both oil-free and oil-lubricated compressors have unique benefits. Oil-free compressors are an excellent choice when air quality is of utmost importance. They eliminate the risk of oil contamination, have lower maintenance costs, and are environmentally friendly. On the other hand, oil-lubricated compressors are cost-effective upfront and suitable for a wide range of applications across various industries. They offer established and reliable technology with a broad selection of sizes and capacities.
When deciding between oil-free and oil-lubricated compressors, factors like the specific needs of your application, budget constraints, and environmental considerations come into play. Making an informed choice ensures that your compressed air aligns perfectly with your operational requirements.
Air Quality Classes for Oil Free Compressors
Compressed air quality is a vital consideration when selecting an air compressor technology. Air Quality Standard ISO 8573-1 serves as the benchmark, evaluating the size and quantity of contaminants, such as oil, dust, and water, in the compressed air. Air quality classes are defined, with most applications favoring Class 2 or lower due to lower oil content. More sensitive industries may opt for Class 1 or the highest standard, Class 0, which provides the best air quality. For reference, here are some recommended air quality classes by industry:
Class 0: Food & Beverage, Pharma, Electronics
Class 1: Metallurgy, Pulp & Paper, General Manufacturing
Oil-free screw air compressors may have a higher initial cost but lead to lower maintenance expenses. They rely on oil solely for internal lubrication, reducing overall maintenance needs.
It’s important to note that oil-free screw compressors may produce slightly higher noise levels due to their dry technology. When selecting an oil free air compressor, the compressor’s location within your facility should be considered to mitigate noise-related concerns.
OIL LUBRICATED COMPRESSOR MAINTENANCE TIPS
Oil lubricated air compressors are commonly used in various industries for generating compressed air. Proper maintenance of these compressors is essential to ensure their efficiency, longevity, and safe operation. Here are some maintenance tips to keep your oil lubricated rotary screw air compressor in optimal condition:
Regular Oil Checks: Check the oil level in the compressor regularly. Low oil levels can cause increased friction and premature component damage. Use only the type and grade of oil suggested by the manufacturer.
Oil Changes: Follow the manufacturer’s recommendations for regularly changing the compressor’s oil. This keeps the oil’s lubricating capabilities efficient and prevents impurities from accumulating.
Air Filter Inspection and Replacement: The air intake filter keeps dust, dirt, and other impurities out of the compressor’s system. Regularly inspect, clean, and replace the air filter if it is broken or clogged. A clogged filter can reduce airflow and reduce compressor efficiency.
Cooling System Maintenance: The compressor’s cooling system is critical for preventing overheating. Clean the cooling fins and ensure optimum airflow to disperse heat effectively. Check for any coolant leaks and repair as soon as possible.
Inspect Belts and Hoses: Examine the condition of the belts and hoses that drive the compressor. To ensure smooth functioning, replace any worn or broken belts and hoses.
Drain Condensate: Condensation can accumulate in the compressor’s tank and lines. Regularly drain the condensate to avoid corrosion and water damage to interior components.
Professional Servicing: While some maintenance activities can be completed in-house, it is best to have a professional technician inspect and service your oil injected air compressor on a regular basis. They can detect possible problems early on and respond correctly. Make an appointment with one of our professionals to have your compressor checked.
