Exhaust Fan sucks in more air than it expells

When running the Chamber Fan aka Exhaust Fan, the fan is sucking in more air than it is expelling. It behaves more like an intake fan than an exhaust fan. Try this test. Turn on your Chamber Fan and place a tissue against the Exhaust Fan rear grate . The tissue will get sucked up the grate. This is not how an exhaust s is supposed to behave. I don’t see how there’s any benefit to the carbon filter that’s behind the fan. I hope that Bambu Lab can come up with a fix that can correct this issue.

P1S: Chamber Fan Direction

Hello! I have just started a HEPA project on the housing fan. Now I realize that my chamber fan is sucking into the printer and not blowing out as I thought. I assumed that the air was being sucked out of the housing through the carbon filter, otherwise it wouldn’t make any sense. Is my fan installed/connected the wrong way round or is that the case? How is it with you, does it blow out or does it suck in?
