ARB Compressor strange noise [Video]

Hi all,

i have a ARB Compressor for the lockers in my Portal Axle Buggy. Everytime it compresses air it sounds really weird since a few months now. I already disassemled it and cleaned it. Also checked for loose fasteners but everything seems okay and in place. The noise must come from the compressor itself. Does anybody have any idea where the noise could come from?
I am really not sure which exact model it is, but i could look it up if someboda is interested.

Thank you in advance and greetings from Germany to the US.

I don't think I hear anything "bad". Can you describe what it is about how it sounds you're worried about?

A few months ago it had a very clean quieter sound. Now it got a lot louder and sounds more "nasty". I am really not sure how to describe it.

Just a shot in the dark, but have you unmounted it from the frame and ran it? Sometimes the sound will vibrate through the steel chassis and make funny noises. I would put a rubber mount underneath the mounts when reinstalling it.

I will do that and video it
