10 Years of Repairing Air Compressors: The Little-Known "Golden Rules" I Only Dare to Share Now(Part 3）

90% of screw air compressors (e.g., Atlas Copco GA series) have small sponge filters hidden inside the intake valve—this "secondary filtration" component is often overlooked. If not washed after 2000 hours of operation, it increases intake resistance and adds 15% extra load to the motor.

Energy-Saving Tip：Use a vacuum cleaner to reverse-blow the main filter (forbid positive blowing with compressed air to avoid impurities embedding in the filter paper), extending its life from 2000 to 3000 hours.
