Product Overview
The Mitsubishi Electric Lossnay VL-50S2-E is a compact, high-efficiency total heat exchanger designed to provide balanced ventilation for individual rooms. As part of Mitsubishi Electric’s Lossnay residential ventilation range, it is ideally suited to modern, airtight homes that require continuous fresh air supply without compromising energy efficiency.
The unit operates using simultaneous supply and extract ventilation, introducing fresh outdoor air while removing stale indoor air in a controlled and energy-efficient manner. Its advanced heat exchanger core recovers both sensible and latent heat, helping to maintain a comfortable indoor temperature while significantly reducing heat losses.
With up to 85% heat recovery efficiency, ultra-low power consumption, and very quiet operation, the VL-50S2-E is an excellent solution for bedrooms, living spaces, home offices, and apartments. Its flexible design allows for both vertical and horizontal installation, making it suitable for a wide range of wall configurations and retrofit applications.
