Bath Fan Vent

The Lambro 3-inch or 4-inch black ABS plastic exhaust vent with snap-in collars is ideal for venting through the roof. It features a damper and screen that prevents outside elements and air from entering the vent. The damper seals the vent opening when the bath fan is not running because no exhaust air exits the vent. When the bath fan operates, the exhaust air pressure pushes the damper to let the exhaust air escape from the vent.

WARNING:The roof vent applications consist only of shingled roof installations.

The exhaust vent is for new and replacement installations. The vent frame comes with six predrilled nail holes to secure the vent to the roof.

The vent’s manufacturing material is ABS (Acrylonitrile Butadiene Styrene) 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.
