If not, please check: The oil used in the crankcase is anti-wear hydraulic oil, grade L-HM68 or 100. It cannot be added into the cylinder! ! ! The oil for the cylinder depends on the load. Generally, L-DAB100 is used, while L-DAB150 is commonly employed. 1. Definition of air compressor load: The symbol for load ISO-L. Operating conditions: Light load – DAA: a) Exhaust pressure = 1000 kPa, exhaust temperature; Medium load – DAB: a) Exhaust pressure = 1000 kPa, exhaust temperature > 160°C, or b) Exhaust pressure > 1000 kPa, exhaust temperature > 1; Low load – DAC. When the above medium-load operating conditions are met and it is expected that carbon deposits will form extensively in the exhaust system using medium-load oil, then medium-load oil should be used. 2. Application conditions for compressor oil – Lubricant type and application conditions: L-DAA (five viscosity grades: 32, 46, 68, 100, 150) is used in piston-type and oil-fed rotary light-load air compressors equipped with lubricating oil. It should not be used in oxygen and chlorine compressors to prevent explosions. It is necessary to regularly clean the carbon deposits in the exhaust valves and exhaust pipes, and to strictly control the appropriate amount of oil supplied. Lower viscosities are suitable for lower exhaust temperatures and pressures. L-DAB (five viscosity grades: 32, 46, 68, 100, 150) is used in oil-lubricated piston and drop-in rotary medium-load compressors; it shall not be used in oxygen and chlorine compressors. L-DAB68 is used in compressors of grades 1 to 2 with an exhaust pressure of 1 MPa or less.
Compressor oil is generally used, mainly due to its high flash point and high oxidation stability.
Indeed, the lubricator for the 4M50 compressors in our facility uses L-DAB150 compressor oil
I agree with what was said above; compressor oil will do. We use 150# oil for our 4m50 as well
Ours is 150# lubricating oil
