I wouldn't think a whole lot of insects could survive the trip through the intake fan.
I draw intake from a room that has had an ac running since may 1st... and I live up north! Works pretty well.

Insects... put a couple layers of stocking over the intake if you are really worried, but if you are drawing from indoors it isn't so much a problem... mites can certainly get through a fan, the indestructible little SHITS
stinkyattic Reviewed by stinkyattic on . Question about intake? Got a few cycles under my belt, but I am for the first time running into some temperature problems. Right now it's 81 in the room, trying to keep things down. As of now I only have an open circuit that is taking warm air out of the room, through the lights, and into the attic via my Vortex fan. There is also a hole in the floor that would be perfect for pulling cold air in... is this the passive intake? In a nut shell I am proposing that I attach some ducting to the whole in the floor Rating: 5
