Lambro Industries gvhaw4 Louvered Vent Hood 4 Inches

Product Description

The LAMBRO INDUSTRIES gvhaw4 is a 4-inch louvered vent hood assembly designed for residential and light-commercial exhaust ventilation applications. It ships fully assembled with the hood, pipe, and collar included, reducing installation time in the field. The built-in bird and rodent guard is removable, making routine cleaning straightforward without specialized tools. The white finish suits standard exterior wall installations. Licensed HVAC technicians and ventilation contractors will find this unit ready to mount directly out of the box.

This vent hood is suited for exterior wall terminations on dryer exhaust, bathroom exhaust fans, kitchen ventilation, and similar low-pressure duct runs. The 4-inch collar fits standard 4-inch round duct, the most common residential exhaust duct size. The louvered design allows exhaust air to exit freely while the closed louvers block outside air infiltration when the system is not running.

Installation Notes

This vent hood is typically installed by HVAC technicians or general contractors during new construction or retrofit exhaust-system work. Shut down the associated exhaust fan or HVAC equipment before beginning installation. Ensure the wall penetration is properly sealed around the collar to prevent moisture intrusion and air leakage. Local building codes and mechanical codes should be consulted for required clearances and exterior termination requirements.
