Dry oil-free screw air compressors are mainly used in food, medical, electronic, fermentation, and other high-end industries. There are strict requirements for the quality of compressed air. Here are some of its advantages and maintenance items.

Use and maintenance

  1. This machine should be used indoors at no lower than 5°C, no higher than 40°C and relative humidity no more than 80%. The surrounding environment must be kept clean, dry, ventilated, and protected from direct sunlight.
  2. It should be placed on flat and firm ground to prevent the machine from shifting during work.
  3. An air filter is installed at the air compressor suction port to prevent dust from entering the air compressor. The filter element of the air filter is blocked after a period of use, which affects the air intake of the air compressor, so the filter element must be replaced regularly. The method of replacement is to open the cover of the suction muffler, take out the filter element, replace it with a new one, and then re-install the cover.
  4.  

Drain the water in the air tank and filters

  1. When the air compressor is running, it will compress the moisture contained in the air and condense it. The accumulation of moisture in the air storage tank will affect the air quality of the air storage tank. Therefore, it must be drained in time. The drainage period depends on environmental conditions. Generally, it must be drained every 3 days.
  2. Drainage method: When there is a certain pressure in the air storage tank, slowly turn the drain valve counterclockwise to make the accumulated water spray out through the drain hose. After draining the water, tighten the handle of the drain valve clockwise to ensure that there is no air leakage.
