What happens if the air compressor uses three filters and one oil for an extended period of time

The "three filters and one oil" of the air compressor have a specified service life, which is generally replaced after 2000 hours of use. If you continue to use it beyond the service life, it will bring a lot of harm to the normal operation of the air compressor

Cold storage anti-corrosion and anti-frost coatings effectively solve the problem of frosting and corrosion

In the cold storage, when the dew point of the air is lowered by the cooling pipe surface, the moisture in the food and air will precipitate and condense on the pipe wall. If the pipe wall temperature is lower than 0°C, it will condense into a rain layer.
