The Lambro 4-inch white plastic exhaust j-channel (j-block) hood vent with 1-inch collar is ideal for venting through the wall. You can easily use the exhaust vent for new and replacement installations over an existing 4-inch opening.
The exhaust vent features an opening and closing spring-controlled 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.
The vent features an opening containing the removable screen with a net-free area of 13.3 square inches, allowing for less back pressure. Removing the screen allows for the net-free area of the unrestricted opening to be 18 square inches. It is crucial to check the inside of the vent regularly to prevent lint build-up when using it 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; we recommend plastic paint for effective painting.
Make sure to check local building codes before installation.
