Lomanco CV3BW 3 Inch White Circle Vent 6 Pack

Product Description

The LOMANCO CV3BW is a 3-inch white circle vent designed for installation in exterior walls and soffits to allow moisture and stale air to escape from wall cavities. Constructed from heavy-duty aluminum, this vent resists corrosion and holds up in exterior applications where long-term durability matters. The drill pop-in design allows for fast installation without the need for specialized tools or fasteners. This listing covers a pack of 6 vents, making it a practical choice for projects requiring multiple penetrations. HVAC technicians, general contractors, and roofers commonly install these as part of a broader ventilation strategy in residential construction and renovation work.

The CV3BW is suited for residential applications where moisture control in wall cavities is a priority. Trapped moisture in exterior walls can cause paint to peel, wood rot, and mold growth over time. By allowing passive airflow, these circle vents help maintain wall assembly integrity. Common installation locations include exterior stud bays, crawl spaces, and soffits. The white finish blends with standard trim and siding in typical residential settings.

Installation Notes

Installation is typically performed by a general contractor, carpenter, or HVAC technician as part of a wall or attic ventilation system. Drill the required opening to the appropriate diameter before pressing the vent into place per the drill pop-in design. Follow local building codes for minimum ventilation ratios when determining vent placement and quantity. Inspect the surrounding wall material condition before installation to ensure a proper seal and fit.
