Imperial Premium Intake Built PAT 4W Review

I have used them as a fresh air supply for a 4" duct heat recovery fan. It is unobtrusive in the home and easy to install, I wish they were made with a built in tilt BUT after much searching it is, like asking for a unicorn.

I thought it was the answer to my external metal vents. No. It looks like it's made out of low quality plastic. Installation was easy, but after three weeks the plastic began to warp from the scorching sun. I'm in Michigan so not too much sun. Looks like I just got a clumsy setup.

It doesn't show the long 10 inch metal line at the end. It doesn't matter because it can just be cut off. However, I didn't have the right tools and didn't expect such a long canal. It was just annoying. and somewhat misleading, but overall a good product.

It easily attaches to the house wall (after drilling a 6 inch hole). The zip tie is long enough to go right through…
