The Lambro 4-in. white plastic soffit exhaust vent is ideal for venting through the soffit. The vent features an opening and closing damper that prevents outside elements and air from entering. The damper seals the vent opening when the clothes dryer or bath fan is not running because no exhaust air exits the vent. When the clothes dryer or bath fan operates, the exhaust air pressure pushes the damper open to let the exhaust air escape from the vent. You can easily use the exhaust vent for new and replacement installations over an existing 4-in. opening. The vent frame comes with 4 screw holes to secure the vent and a caulk-friendly frame for completing the installation. The vent features a sufficient opening with a net-free area of 11 sq. in. to allow for less back pressure. Make sure to check the inside of the vent regularly to prevent lint build-up when using the vent to exhaust a clothes dryer. The vent’s manufacturing material is polymer resin with a UV additive to prevent premature fading caused by sunlight. It would be best to prep the vent before painting it; we recommend plastic paint to paint the plastic vent effectively. Make sure to check local building codes before installation.
