1、 Air filter, we can use the naked eye to distinguish. The paper density and quality of the filter element can be distinguished by naked eyes. If the filter element is of poor quality, a large amount of impurity dust will enter into the air compressor, block the oil core, generally the internal pressure is too high, and the safety valve will open and spray oil.
2、 Oil filter. The quality can not be identified by naked eyes, only through the use of time. If the blockage alarm or low oil pressure before the specified time leads to high exhaust temperature, it is caused by oil filter blockage. If the quality of oil filter is poor, it will also lead to air compressor failure.
3、 Oil gas separator, its cost is relatively high, so the price is also high. The quality of the imported oil-gas separator is better, especially the pressure difference ratio and oil filtration. Generally, the imported oil-gas separator can basically guarantee no oil core separation failure.
4、 Screw air compressor special oil, oil is the blood of air compressor, no good oil, air compressor can not run. For more information about Weifang screw air compressor, please visit our website: http://jz418.cn .
