Single Room Through Wall Systems
Through-wall single room ventilation systems provide efficient ventilation by installing directly through an exterior wall, offering fresh air and removing stale air without the need for ductwork.
Single room through wall ventilation systems offer a highly efficient, compact solution for improving indoor air quality in homes or small commercial spaces—without the need for extensive ducting or ceiling space. At HVAC NZ, we supply advanced wall-mounted systems that bring in fresh air, remove stale air, and recover heat in the process, making them ideal for spaces where traditional ducted systems are not an option.
A standout in this category is the Mitsubishi Electric Lossnay VL100, which is specifically designed for easy through-wall installation. Requiring just two 75mm diameter holes, this system is perfect for rooms up to 90m² and is an excellent option for properties lacking roof space or ducting infrastructure. The VL100 provides balanced pressure ventilation, meaning it introduces filtered fresh air while simultaneously extracting stale, moisture-laden air—without creating pressure imbalances in the room.
Thanks to its energy recovery heat exchange system, up to 80% of the heat from outgoing air is retained, pre-warming or pre-cooling the incoming air. This reduces the load on your heating or cooling system, lowering your energy bills and contributing to a more comfortable, healthier living environment. Quiet operation (from just 25dBA), easy-clean filters, and low power consumption (15–31W) make it a practical choice for bedrooms, home offices, and enclosed living areas.
Whether you’re dealing with excess moisture, poor ventilation, or simply want cleaner, fresher air indoors, our single room through wall systems provide a smart, efficient, and affordable solution that works all year round.
