The Vents PS101 Passive 4" Air Vent with slate Grey exterior grille is a practical solution for bringing fresh air into homes, cottages, offices, and other residential spaces without the need for powered ventilation. Designed for through-wall installation, this passive wall vent helps improve indoor air quality by allowing a steady supply of outside air to enter the space while keeping windows closed.

Ideal for residential ventilation applications, the Vents PS101 helps reduce drafts, outdoor dust, and street noise that often come with open-window airflow. During colder months, it can also help limit heat loss compared to traditional window ventilation, making it a smart option for homeowners looking to maintain comfort while supporting better airflow and energy efficiency. It comes complete with a sliding level to fine tune the opening of the fresh air vent inside the unit.

The PS101 is well suited for use in houses, tiny homes, cabins, offices, and other spaces where simple fresh air ventilation is needed. It can also be used to support room-to-room airflow in properties without ductwork. Commonly installed above or near a window, this passive fresh air vent offers a clean, effective way to improve background ventilation with a modern slate gray exterior finish.

Its primary function is to deliver fresh air without the need to open windows, all while effectively blocking out dust and street noise.

During the winter months, the Vents PS101 helps conserve heat by preventing heat loss through open windows or window vents. This leads to potential savings on heating costs while still allowing some fresh air circulation. They can also be used for "room to room" airflow for dwellings without ducting.

These wall vents are typically installed in the exterior walls of various spaces, such as homes, tiny homes, cottages, and office buildings, typically positioned above or near a window.
