The air compressor used in the summer and winter use lubricating oil should be distinguished from, because oil has a characteristic is the viscosity decreases in the high temperature condition, and under the condition of low temperature viscosity.

    So the air compressor according to the different season or temperature to select the appropriate lubricating oil, lubricating oil viscosity is larger the greater the number. In the case of a conditional, summer and winter, the lubricating oil should be strictly separated.

    In the general air compressor, cylinder, filling part with 19 compressor oil in the summer, winter 18 compressor oil. Crankshaft connecting rod part in the summer - with 50 mechanical oil. Winter can be 30, No. 40 mechanical oil, such, can make the air compressor lubrication more good. General single role of small air compressor used in winter 13, summer 19 compressor oil, compressor oil.
