Why the air filter regulator has the problem of leakage?

In some cases, the air filter regulator has a leakage problem, which will affect our normal production and lower the working efficiency.

Now I am going to point out one common reason for the leakage.

Like the photo below, after a while of working, if the compressed air is not very clean and dry, the dirt will stay on the face of the part, also causing the rust problem, this will bring the problem of leakage.

So, when we find the leakage problem, it is not difficult to fix it, just disassemble the air filter regulator, clean every part, remove the rust, this will help the air filter regulator to perform again.
