4" Inch Wall Vent

  • When venting through a wall is the best option a quality wall vent should be considered; the 4 inch wall vent by Vent Works was designed with a spring loaded back draft damper to prevent drafting from outdoors, we also included a ¼” inch metal screen. These heavy gauge vents are not available at your local home improvement or general hardware stores. There are 3 different material options; galvanized (26 gauge), white powder coated steel (26 gauge) and aluminum (high grade). Our vents are used in a wide variety of commercial and residential applications including heating systems, bathroom exhaust, kitchen exhaust, laundry room exhaust, venting spray booths, laser engraving machines, exhaust fan blowers and virtually anything else with a 4" inch round exhaust.

    To Install: Cut a 4-1/8” inch hole in the side wall and install, be sure to seal it.

  • Is there a screen in the vent?

    Yes; our wall vents come with a 1/4” inch metal screen.

    Can it be used for dryer venting?

    No; these wall vents have a fixed screen in them, this screen is not removable and as a result it’s not optimal for dryer venting. If you do use a screened vent you should remove and clean the screen regularly because it will build up lint quickly.

    Can I use this with a bathroom exhaust fan?

    Yes; Try to match the bathroom fan exhaust outlet with the wall vent, it’s best when the diameter of the fan outlet, vent and duct are all the same e.g. if the bathroom fan’s outlet is 4 inch use a 4 inch wall vent with 4 inch ducting etc. If needed use a reducer to decrease/increase the diameter size to bridge the gap of difference from your fan to vent.

    Can I use this with a kitchen exhaust fan? (range hood)

    Yes; Try to match the kitchen fan exhaust outlet with the wall vent, it’s best when the diameter of the fan outlet, vent and duct are all the same e.g. if the bathroom fan’s outlet is 7 inch use a 7 inch wall vent with 7 inch ducting etc. If needed use a reducer to decrease/increase the diameter size to bridge the gap of difference from your fan to vent.

    Can this function as an intake vent?

    Yes & No; It can’t function as an intake vent without modification because the damper only goes one way to exhaust air out but if you removed the damper and left the screen intact you would have a fresh air intake vent. The easiest thing to do would be to purchase a screened vent made for intake applications. 

    Can the screen be removed?

    No; these wall vents have a fixed screen in them, this screen is not removable but we have a version with damper only.

    .

    What size hole do I drill for the pipe?

    The duct (pipe) is 4” inch diameter so you'll want to drill a 4-1/8" diameter hole through the wall for the duct to fit properly.

    .

    Can I mount on a roof?

    No; it’s not designed for that application wall vents are designed to be installed through a side wall, you should use a roof vent.

    Can the duct pipe be cut down?

    Yes; the duct that comes off the back of the vent can be cut down with sheet metal sheers or a hacksaw.

    Can the wall vent be painted to match my house color?

    Yes; first prep by wiping down with a solvent like lacquer thinner or paint thinner to remove all oil residue so primer will adhere properly. Then use an epoxy or etching primer as a base. Then paint it with the color matched paint.
