Review on Imperial Premium Intake Built PA 4W by Victor Halla

Seems a bit pricey considering its all plastic but looks like it will last. My only criticism of this is that the pest net has larger holes. So if you want to keep small bugs out, use a finer mesh. I had an old window screen and it was very easy to put it in place with the metal screen (spread out the vent neatly, wrap the thinner screen around the metal it comes with and put everything back together). I like the way the vents look and I think they will allow for good airflow. Using a 4 inch hole saw, cut a hole in each gable of my shed, fitted a vent, drilled screw holes, took the vent out, applied a bead of sealant to the tubular, put it back in the hole and installed the screws. I also sealed the vent in the shed. I'm sure it was overkill, but open sealing is good for a while anyway. Do your own research but this was the best price I could find for what I was looking for, especially compared to the big stores.
