When the high-pressure airless spraying machine operates continuously for a long time and the phenomenon of frost accumulation inside and outside the muffler is severe, a water separation filter and air dryer can be installed before compressed air is input into the spraying machine, and the muffler can be removed. Alternatively, replace the oil in the oil mist atomizer oil cup with antifreeze for the car water tank. The water separation filter and air dryer are selected or self-made by users according to their actual needs. Anti freeze liquid for car water tanks can be purchased from all over the country.
