Air compressor is not pumping air no pressure.
Can not find serial number
The flat round part like an inlet valve or muffler is not working. Need to get the part shown.
I doubt that the intake filter is your compressor problem.
Does the machine work OK with this part removed?
But if it’s really clogged, check the threads to see if they’re SAE or British.
You should be able to find a replacement at a small engine shop, or your local big-box store.
As long as you can thread it in and the filter housing is the same or bigger than the old, you should be good to go.
