The benefit of fresh air
Stale air with higher levels of CO2 is a common problem not only in schools and offices but also in homes where structures are becoming more and more airtight due to more stringent building regulations.
High levels of CO2 can affect concentration and learning as well as overall wellbeing and productivity. Furthermore, the lack of natural ventilation in airtight spaces can lead to the build-up of moisture-laden stale air. This is the perfect breeding ground for mould that can trigger allergy or respiratory problems.
The option of leaving doors and windows open to allow fresh air to enter is not always desirable or practical, with potential security risks and greater exposure to outdoor noise.
This is where a fresh air ventilation system like Lossnay can make a real difference.
Balanced pressure energy recovery ventilation
The Lossnay VL100 Range includes a ducted model that is the perfect unobtrusive in-ceiling solution. For applications without adequate roof space, there is a ductless unit purpose-built to accommodate a simple back-to-back wall hung installation.
The balanced pressure ventilation system captures and filters fresh outdoor air (as opposed to stale attic air) to replace indoor stale air for an all-round healthier, drier and warmer room.

The Lossnay Core
The Lossnay Core recovers energy from the extracted stale air, to pre-warm or pre-cool the incoming air.
As a result, an existing heating appliance in the room does not have to work as hard to reach desired temperatures, maximising energy efficiency and reducing your energy bill.

Single Room VL100 Ducted Ceiling Mount Fresh Air Energy Recovery Ventilation
This ducted model is specifically designed to provide energy efficient ventilation to ensure an individual room has a constant supply of filtered fresh air whilst minimising moisture build-up. Furthermore, incoming air is pre-warmed (or pre-cooled) so your existing heating appliance does not need to work as hard to reach desired temperatures.
Key specifications of the VL100 Ducted
- Up to 64% heat exchange efficiency
- Low height 204mm
- 100mm duct diameter
- Lightweight and compact
- Low noise operation from 25dB on low fan speed
- Filter replacement notification
- Air intake can be installed away from the unit in the most convenient location
- Ideal for residential or small commercial applications with ceiling void or roof space

Single Room VL100 Wall Mount Fresh Air Energy Recovery Ventilation
This wall mounted unit provides an effective balanced pressure ventilation solution for a specific area up to 90m2*. Lossnay recovers energy from the air being transferred to pre-warm (or pre-cool) the fresh air drawn into the room. As a result, moisture build-up is minimised and a warmer, drier and healthier indoor environment can be maintained all year round.
Because this model is ductless in design, it is ideal for applications where there is no roof space to accommodate the heat exchanger and duct work.
Key specifications of the VL100 Wall Mount
- Up to 80% heat exchange efficiency
- Simple installation by drilling two 75mm diameter installation holes
- Low noise operation from 25dB on low fan speed
- Easy to clean filters
- Ideal for residential or small commercial applications where there is no roof space

Energy recovery ventilation works all year round
In winter a traditional ventilator captures fresh air at the cold outside temperature. Lossnay Ventilation preheats the outside air before bringing the fresh, filtered air inside.

In summer a traditional ventilator captures fresh air at the hot outside temperature. Lossnay Ventilation lowers the outside air temperature before bringing the fresh, filtered air inside.
