Description
Mitsubishi Electric Lossnay: Single Room Ventilation & Energy Recovery
The Mitsubishi Electric Lossnay VL100 is a wall-mounted ventilation system designed to provide cost-effective energy recovery to specific areas of your home. By capturing fresh outdoor air and filtering it, Lossnay replaces indoor stale air for a healthier, drier, and warmer environment.
Because this model is ductless, it is the perfect solution for homes where there is no roof space to accommodate traditional heat exchangers and ductwork.

- Simple Installation: Requires only two 85-90mm diameter installation holes.
- Ultra-Quiet: Low noise operation starting from just 25dB.

- Coverage: Effective for areas up to 88m² (based on 0.5 air changes with 2.4m ceiling height).
Who Can Benefit?
| Application | The Solution |
|---|---|
| Tiny Homes & Studios | Solves moisture build-up in compact, airtight spaces where ducted systems aren’t practical. |
| Renovated Spare Rooms | Ideal for home offices, gyms, or hobby rooms converted from older, stale spaces. |
| Overheating Rooms | Purges summer heat without the need to open windows—perfect for noise or privacy concerns. |
| No Ceiling Space | A standalone option for existing homes that cannot accommodate bulky ductwork. |
The Lossnay Core: Advanced Energy Recovery
The secret to Lossnay is our patented Heat Exchanger (Lossnay Core). Unlike traditional ventilators that bring in cold or hot outdoor air directly, Lossnay recovers energy from the air being extracted to pre-condition the incoming fresh air.
- In Winter: Lossnay pre-warms the cold outside air before bringing it inside.
- In Summer: Lossnay cools the hot outside air before bringing it inside.
As a result, your existing heating or cooling appliances don’t have to work as hard, reducing your energy bills while maintaining a constant supply of filtered oxygen.
Healthier Air, Better Wellbeing
Modern homes are becoming more airtight to meet building regulations, which often leads to high COâ‚‚ levels and trapped moisture. High COâ‚‚ can affect concentration and overall wellbeing. The VL100 Lossnay system ensures your rooms stay fresh with a constant supply of filtered outdoor air, preventing moisture build-up and creating a drier, healthier indoor climate all year round.
Case Study: Airtight House Solution
This system was successfully implemented in a well-insulated property in Rangiora, Canterbury. The homeowners needed a way to reduce condensation and ensure high-quality air without the space for extensive roof ducting. The VL100 provided the perfect balance of efficiency and ease of installation.
