An oil lubricated compressor draws air into a storage tank after compression within the airend which houses the screw rotors. These rotors are lubricated using oil that helps in the dissipation of heat generated during the compression process. The oil injected in the compression chamber keeps the system cool by dissipating the heat and acting as a lubricant to lower the friction between the moving parts. Oil lubricated screw air compressors or Pressure lubricated air compressors are efficient, reliable, quieter, and last longer. Their ability to work quietly makes them effective for various pneumatic tools and accessories. The oil-lubricated screw air compressors are best suited for industries that do not have stringent requirements for maintaining air quality and the compressed air doesn’t come in direct contact with the end product. The type of oil flooded air compressor suitable for you depends on the application. There are different oil-lubricated air compressors, each with different capacities and pressure ratings which can address different application requirements.
ELGi’s range of oil injected screw compressors offers maximum productivity due to high uptime. The lubricated or oil injected screw air compressors from ELGi have a unique rotor design which offers high energy efficiency, and a sophisticated control panel that facilitates remote monitoring & fault diagnosis (for select controller models).

OIL LUBRICATED VS OIL FREE COMPRESSORS
ADVANTAGES
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.
CONSIDERATIONS
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
MAINTENANCE COSTS
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.
NOISE LEVELS
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 changing the compressor’s oil on a regular basis. 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 and repair any leaks 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. Drain the condensate regularly to avoid corrosion and water damage to the components inside.
Professional Servicing: While some maintenance activities can be completed in-house, it is best to have an experienced 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.
