Bathroom and kitchen exhaust fan vents

--------------------------------------------------------------------------------

I have a 290 cfm remote, 4 port bath exhaust fan serving two bathrooms. The exhaust port is 6 inches in diameter.

I will be installing a 360 cfm range hood exhausting to 6 inch pipe.

Can I join both kitchen and bath exhaust pipes in the attic and have the exhaust for both run out the same opening in the roof?

Yes you may. In vents it's called reventing. Good luck, Tom
