Do they work? Don't care about air resistance. Just need to know if they flow and are light tight.
Here's a tip... you can dismantle those things, and you will see that they consist of 4 layers put together....This means, as long as you don't need the 100% light proofing, each darkroom louver actually equals TWO of them!
@hush wait...are you telling me that I could save a ton of money by dismantling an 8x8" louver & making it into a 8x16" intake?
