Time between meat and dairy in same oven

How much time do I need to wait in between using my oven for meat or dairy before using it for the other. This is assuming the items are uncovered

Thank you

No need to wait in between.

Why is there no concern of zei’ah here when cooking uncovered?

Our ovens have venting systems and therefore no zei’ah.

Hi. May I assume this is true also if one used the convection setting in an oven like this, which has “true convection”? Thank you.
