Single Room Fresh Air Ventilation with Lossnay Energy Recovery


The wall-mounted VL100 Lossnay Fresh Air Energy Recovery Single Room Ventilation unit provides energy efficient ventilation to ensure individual rooms have a constant supply of healthy, fresh air with the additional benefit of energy efficient heat recovery at the same time. And because the unit is ductless in design, it means the system is ideal for homes and buildings where there is no roof space to install a heat exchanger.

Balanced Pressure Heat Recovery Ventilation Solutions

Lossnay by Mitsubishi Electric, is an advanced Fresh Air Heat Recovery Ventilation System that captures and filters fresh outdoor air (as opposed to attic air) to replace indoor stale air for an all-round healthier, drier and warmer home. But what makes Lossnay so different from other ventilation systems is our patented Heat Exchanger, which is the secret to the heat recovery capabilities of the Lossnay ventilation unit and provides several important benefits.

Why Outside Air, Not Attic Air?

Not all air is created equal. Lossnay only draws fresh air from the outside – it does not draw air from the attic. The absence of significant air movement common in attics means the air is likely to be stale. In addition, build-up of dust, dirt and other contaminants such as mould, insect and rodent droppings makes this air much harder to filter before it is distributed through your home. This is why the Balanced Pressure Lossnay System specifically utilises direct fresh air instead.

Balanced Pressure Ventilation

Ideal for rooms in modern homes that are more airtight

A well ventilated room is vital as it maintains air quality; creating a healthier and more comfortable environment. The Mitsubishi Electric Lossnay System is a patented energy recovery ventilation solution that uses fresh outdoor air to ventilate a room. The system works by extracting stale air from inside a room and replacing it with fresh air from the outside, whilst recovering heat energy from the extracted air.

Retains Heat

Assists Moisture and Condensation Control

Lossnay effectively reduces moisture in your home by directly removing stale air that causes condensation via the Lossnay core.

Energy Efficient

Energy Efficient

Incoming fresh air is pre-warmed so your heating system isn’t required to work as hard to reach desired temperature. This is highly energy efficient, and can help reduce heating bills.

Retains Heat

Retains Heat

Lossnay’s unique Heat Recovery Technology collects up to 80% of the heat energy in outgoing air which is then used to pre-warm or cool the fresh air vented in.
