Conflicting Information

"Built in screen to prevent insect entry (Must be removed if using for Dryer Venting)" is in the description then the tech says "You can't remove it without professional assistance." Well which is it? I want critters to stay out but want to use for a dryer. Can't the screen just be made so it is removable? Once a month remove, rinse and reinstall. That's how my current one is but it is on the roof. I am trying to keep from having to climb up onto my roof once a month. This is unnecessarily dangerous and i want to be able to clean my vent while on the ground. Nice and safe.
Asked by: RobertoOnTheRoof
When using this as a dryer vent, yes....the screen MUST be removed or you will overheat your dryer and risk a fire. Removing the screen is easy by using a sharp utility knife (it's just metal window-screen). Cut the screen out from the "duct" end before installing it.....easy!! My dryer is in the basement, with the vent installed only 16 inches above the outside ground level. While we have plenty of bugs and "critters," I've never had any problem of them entering through the vent, after 15 years of use.

How to use as dryer vent at end wall

When used to vent dryer to outside home wall: how can critters be prevented from entering while avoiding lint buildup?
Asked by: kimfit
When using this as a dryer vent, your concern about lint build-up is valid. The screen MUST be removed or you will overheat your dryer and risk a fire. Removing the screen is easy by using a sharp utility knife (it's just metal window-screen). Cut the screen out from the "duct" end before installing it.....easy!! My dryer is in the basement, with the vent installed only 16 inches above the outside ground level. While we have plenty of bugs and "critters," I've never had any problem of them entering through the vent, after 15 years of use. The built-in flapper seems to be doing it's job. Notes: - If it's to be used for a bathroom vent, leave the screen in. - This vent may also be painted to blend with your exterior finish. (see photo)

how do you remove the insect entry screen

Asked by: matt
As noted below, the screen is not designed to be removed, however...... When using this as a dryer vent, the screen MUST be removed or you will overheat your dryer and risk a fire. Removing the screen is easy by using a sharp utility knife (it's just metal window-screen). Cut the screen out from the "duct" end, running the blade next to where it's held by the aluminum. It will come out in one, circular piece.....easy!!! My dryer is in the basement, with the vent installed only 16 inches above the outside ground level. While we have plenty of bugs and "critters," I've never had any problem of them entering through the vent, after 15 years of use. The built-in flapper seems to be doing it's job.

What are the dimensions of the vent frame?

4 in is the diameter of vent pipe. The exterior of my hour is stucco and the cut-out rectangular opening for the dryer vent is five and 3/4 in. by six in.
Asked by: buster
The vent we purchased is 6 1/2" wide x 7 1/4" tall overall. It is designed to sit flush against the outside of your building utilizing a hole large enough to pass a 4" pipe (4 1/4"- 4 1/2" diameter). It can be secured by screws through the flange or high quality adhesive caulking under the flange, or ideally both.

The "flap" works well. I Drilled a hole through my wall, and it installed fine. However, the pipe portion is not long enough to reach through even a 2x4 thick wall. I had hoped to be able to hook the elbow on the inside of the wall directly to the wall vent. However, it is short enough, I had to get a straight pipe extension to attach to this vent to extend inside the interior of the house so I could then attach the elbow connection on the inside. I would probably not buy this again, and find one with a longer pipe.

This is the best gosh darn 4" round wall vent that IO have ever installed! The cool shine of the all aluminum body, they easy motion of its flap, the even grid of its screen, and a full 8.5 inches of exhaust area. If you are in need of a totally superior, solid metal, 4" round wall vent then this baby is for you.

This seems to be pretty well constructed and like the fact it has a bug screen and foam padding to keep the flapper from making a lot of noise when the wind blows. Install was easy, had a tough time installing a 4" insulated hose of the pipe, but after making a small cut in the pipe with tin snipes I was able to slide the hose over it. There wasn't any holes drilled in mine, I drilled three across the top and three down each side, I know over kill but don't want any leaks.
