Quick question - insect screen

[m2e]

Just wondering, for inlet louvre, you'd use insect screen, but for exhaust louvre, would you also use insect screen? Or does it depend whether it's a ducted exhaust or just a louvre on the wall?

Thanks.

I would use the insect screen for exhaust, unless it was a laundry dryer or grease hood exhaust. No screens for those.

I would think that insects wouldn't care whether they came in on the inlet or the outlet. Having a bunch of wasps coming into the kitchen through the stove hood would be quite disconcerting.

Think of when the fan is not in operation (I just pulled a dead bird from my laundry drier that got in throught the exhaust. Took me a while to find out why my basement smelled so foul)

Thanks for sharing your interesting experience. Dead bird and wasps aren't exactly what I hope to get into the ducts. I'd put the screens at both intake and exhaust now. Thanks.

I almost never specify an insect screen unless a fan is expected to be dormant for long periods of time (weeks, not hours). Every maintenance guy that I have ever talked to despises insect screens because they clog up so easily.
I have been specifying bird screens ONLY for years and have yet to have any insect invasion problems in my systems.

If this exhaust is likely to carry solids like a dryer's I'd put a spring louver. Just in case
