The Lambro 4 inch exhaust wall vent with floating damper prevents outside elements and air from entering the vent when the clothes dryer or bath fan is not in use. When the clothes dryer or bath fan is in use, the exhaust air pressure pushes up the floating damper. The exhaust air escapes from the vent’s bottom. When the clothes dryer or bath fan stops, the damper drops back down to keep outside elements from entering the vent. Made of HIPS (high impact polystyrene), the exhaust wall vent mounts easily over an existing 4 inch vent pipe and can be painted.
Features:
- Replaces traditional clothes dryer or bath fan wall vents
- Floating damper prevents outside elements from entering the vent
- Mounts over existing 4 inch openings
- Made of HIPS (high impact polystyrene)
- UV inhibitor is used to help prevent the premature fading of vent
