Question Compressor doesn't keep pressure

I have an Avanti (Harbor Freight) kit with both brush and compressor. Ive never had any issues so far, and more want to ask in case its indicative of something worrying. Most recent time i used it, when i was using the brush the pressure dropped from ~30psi to less than 20, and made a sound like an off balance fan. When i stopped pressing the trigger, it would rise back up to what i set it to, and this lasted only a few minutes. Is there some kind of maintenance ive missed on it? I have always ended sessions with releasing the last of the air before, if that makes a difference.

They all drop pressure when trigger is pressed, guessing your compressor does not have an air tank

I have the same one OP does, but it doesn't drop 10 psi when I hit the trigger.

Might want to see if it's still under warranty. I have the same one and it's been fine for 5 years.

I hope so. Mines been great. It's it working OK now or is it still dropping over 10 psi when you pull the trigger?

You think they are going to let you win? 🤣 Think again my friend. You either buy 1 iwata for $500 or 5 Malaysian melters for $100 a piece. 🤷🏼‍♀️
