   Osman screw compressor lubricant incorporates advanced viscosity-temperature stability and pressure-responsive viscosity technologies, resulting in an average reduction of 5% in compressor energy consumption. Under high-temperature operating conditions, it forms a directionally aligned, layered lubricating film that ensures the compressor's performance remains consistently stable. Furthermore, it guarantees highly efficient and energy-saving operation across varying pressure levels, effectively resolving issues associated with high viscosityand the resulting excessive resistance and power consumptionthat typically occur during low-pressure operation. At standard pressures, the lubricant effectively adjusts its viscosity to enhance sealing performance. At medium to high pressures, it significantly boosts compressor operational efficiency, ensuring the equipment maintains long-term stability and operates in its optimal state. By utilizing Osman screw compressor lubricant, users can achieve a 30% reduction in compressor maintenance costs.

Functions:

1. Lubrication: Reduces friction between critical componentssuch as screws, bearings, and gearsthereby extending the service life of the equipment.

2. Cooling: Through continuous circulation, the lubricating oil absorbs internally generated heat; this helps lower the equipment's temperature, prevents overheating failures, and serves a vital cooling function.

3. Cleaning and Filtration: Captures contaminants and impurities (such as dust and moisture) carried in the intake air, thereby protecting internal components from damage.

4. Sealing: Within the compression chamber of the screw air end, the lubricating oil forms an oil film that fills the minute clearances between the rotors and the casing. Acting as a dynamic seal, it minimizes gas leakage to ensure compression efficiency, while simultaneously sealing and lubricating the bearing areas to enhance the system's overall airtightness and stability.

5. Noise Reduction:Lubricating oil for screw compressors helps mitigate noise generated during operation. By providing effective lubrication, it reduces friction and vibration between mechanical parts, thereby serving a passive noise-reduction role that lowers operational noise levels and improves the working environment.

6. Protection:The lubricating oil provides protective benefits to the screw air compressor, specifically offering corrosion resistance and protection against dust ingress.

How to determine the amount of oil to add to an air compressor?

The amount of oil to add is not fixed; it mainly depends on the air compressor's discharge capacity (m³/min). You can refer to the following approximate range, but the most accurate guide is the equipment manual.

        • 1-2 m³/min: Approximately 10-15 liters
        • 2-4 m³/min: Approximately 20-25 liters
        • 5-10 m³/min: Approximately 35-50 liters
        • 10-20 m³/min: Approximately 50-75 liters
        • 25-40 m³/min: Approximately 100-150 liters

The oil level should be maintained between the "MIN" and "MAX" marks on the dipstick. Adding too much oil will increase oil consumption and strain on the separator; adding too little oil will result in insufficient lubrication.

Precautions for using screw compressor lubricating oil:

1. Regular inspection: It is recommended to check the oil condition every 500 hours. If the oil turns black, becomes cloudy, has an unusual odor, or emulsifies (the oil becomes cloudy like milk), it indicates that the oil has oxidized or become contaminated and needs to be replaced immediately.

Note: What to do about oil emulsification? Oil emulsification is caused by water contamination, usually due to cooler malfunction or excessively high ambient humidity. The cooling system needs to be checked, and condensate should be drained from the air compressor and air tank regularly.

2. Replacement cycle: Replace the lubricating oil and oil filter every 500 hours for the first maintenance. Subsequent major maintenance recommends replacement every 2500-3000 hours or annually. If the equipment operates in harsh environments, the cycle should be shortened accordingly.

Replace filters simultaneously: When changing the lubricating oil, be sure to replace the oil filter, oil-air separator, and air filter simultaneously to ensure the cleanliness of the new oil and achieve optimal performance.

3. Use the special coolant for screw compressors, which is a lubricant specifically designed for air compressors.

4. The oil used must meet the requirements. Do not mix lubricating oils from different manufacturers or of different models to avoid high-temperature coking and the risk of the oil burning out the unit.

5. Follow the oil change schedule. The oil change interval is 2500-3000 hours. It is best to perform a system oil cleaning with lubricating oil after two years of use.

6. When changing the lubricating oil, the oil filter must also be replaced.
