Lossnay ventilation

VL-250-500CZPVU Vertical Lossnay


Compact mechanical ventilation with heat recovery for your home. Removes both moisture & stale air and brings in fresh, filtered air from outside.

  • Fresh air without windows open
  • Designed for airtight modern homes
  • Assists moisture & condensation control
  • Retains heat
  • Bypass mode to bring in cool, fresh outside air

Bypass mode to bring in cool, fresh outside air

Using onboard temperature sensors, the unit automatically enters bypass mode when it detects the space is hotter than desired and the outside air is cool enough. Bypass mode allows the unit to bring in fresh air from outside without recovering the heat helping to reduce the need for air conditioning cooling, such as overnight in summer.

Heat recovery ventilation

Heat is recovered from both outgoing stale air as well as from damp areas such as kitchens and bathrooms. This heat is utilised to pre-heat incoming fresh air so your heating system is not required to work as hard to maintain desired room temperature.

New compact vertical design

The Vertical LOSSNAY boasts several key new features including a compact slimline design (it’s small enough to fit inside a cupboard), low noise output, and both left and right configurations.

Optional NOx or PM2.5 filters

A third filter slot can hold an optional NOx (nitrogen oxides) filter on the supply side of the unit to clean incoming air in polluted environments. The third filter slot can alternatively hold an optional PM2.5 (particulate matter 2.5) filter providing a high standard of fresh air filtration.

Reduce air conditioning heating load

The Vertical LOSSNAY can contribute to as much as 40-46% in energy savings on reduced air conditioning loads depending on conditions. Full energy consumption, CO2 emissions, and electrical expense calculations are available upon request.

Removes both moisture & stale air

Removes both moisture & stale air

Ideally suited to residential buildings including multi-stories or homes located in inner-city locations concerned with localised air quality, the LOSSNAY technology continuously removes stale interior air from bathrooms, kitchens, toilets, and the laundry. Heat is then transferred to the incoming fresh air to warm the home on a cool day. This allows maximised energy efficiency of ventilated air while reducing the demands on air conditioning for heating.

Simultaneous air supply and exhaust

Simultaneous air supply and exhaust

Lossnay is the ultimate home ventilation system that provides fresh clean air from outside, while removing both moisture and stale indoor air at the same time. Bringing in fresh air into the house can help improve air quality by lowering the amount of CO2.
