When this is the case in your equipment, it means that the compressed air contains oil. If you have the right tools at your disposal, it is recommended that you check the filter unit element as follows.
Step 1: The device is powered off
01 Close the software
02 Turn off the power button on the side of the device's control panel
03 Turn off the solenoid valve switch of the filter unit of the equipment
Step 2: Rotate the size 22 open-end wrench clockwise as shown in the diagram below until you can manually rotate the bowl to remove it
Step 3: Rotate the black knob clockwise to remove the filter
Step 4: Remove the other filter in the same way
It can be seen that 2 filters are already visibly contaminated and need to be replaced immediately.
Step 5: Check that the check is complete and reinstall the bowl
Tighten it by hand first, and then gently tighten it with an open-end wrench, and do not use blind force to prevent the thread of the filter cup from being screwed.
