Vents PS 101 Wall Vent Kit 4" with Mahogany External Grille

The Vents PS101 Passive 4" Air Vent with Mahogany exterior grille is an efficient fresh air solution for homes, cottages, cabins, offices, and other residential or light commercial spaces. Designed for through-wall installation, this passive wall vent helps improve indoor air quality by allowing outside air to enter the room without the need to open windows or use powered ventilation.

Perfect for spaces that need simple, reliable background ventilation, the Vents PS101 helps reduce the dust, noise, and discomfort often associated with open-window airflow. In colder weather, it can also help reduce heat loss compared to traditional window ventilation, making it a smart choice for maintaining comfort while supporting energy efficiency. The unit also includes an interior sliding lever, allowing you to easily adjust and fine-tune airflow as needed.

The PS101 is a versatile option for houses, tiny homes, cottages, offices, and other spaces where fresh air circulation is important. It can also be used to support room-to-room airflow in homes or buildings without ductwork. Commonly installed above or near a window on an exterior wall, this passive fresh air vent offers a practical ventilation solution paired with a warm mahogany exterior grille finish for a more refined architectural look.
