Air flow, IN or OUT

[DLBOONE]

Hi, I just installed a circulating air fan to my FI 2100 still air incubator. The air flow goes out from the vent hole, is that correct? Just want to make sure. Thank You

It should just move air around inside the incubator, not necessarily in or out.
Blowing air in or out will bring cool air in the other vents making the heat element work harder.
There does need to be some air brought in, especially the last 2 weeks for oxygen for the embryos.

Thanks for the answer. It does have about a 1/2 inch vent hole that is to line up with the vent hole of the bator top. So there has to be air flow, I would think??
