Questions & Answers

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.

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. 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)
