Lambro 143B 4 Inch Exhaust Soffit Dryer Vent

Product Overview

The Lambro 4-inch exhaust soffit vent with 3-inch pipe is ideal for venting through the soffit. The soffit vent features an opening and closing damper that prevents outside elements and air from entering the vent. 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-inch opening. The vent frame comes with four 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 square inches 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 made of polymer resin with a UV additive to prevent premature fading caused by sunlight. You need to prep the vent before painting; plastic paint is recommended for effectively painting the plastic vent.

Make sure to check local building codes before installation.
