How It Works The Balanced Pressure Lossnay Heat Recovery Ventilation System removes stale, dirty air and draws in fresh air from outside. Lossnay also recovers heat energy from the air being transferred to pre-warm (or pre-cool) the fresh air being drawn into your home. The VL220 model is ideal for small to medium sized homes between 52m2 and 192m2. EXTRACTS STALE AIR Extracts stale air removing toxins and reducing humidity. SUPPLIES FRESH AIR Supplies fresh air increasing the oxygen levels in the home and assists with managing the build-up of moisture. HEAT RECOVERY Recovers up to 86% of the heat energy from the outgoing air to preheat the incoming air, saving you money.

The stale air extracted from your home is Return Air (RA). Return Air can contain high levels of CO2, odours and other pollutants. This Return Air stream also contains heat energy that Lossnay can recover, which is not the case with positive pressure ventilation systems. 2. As the stale Return Air is removed, Lossnay’s core ‘recovers’ the useful heat energy from it. The air is then exhausted (EA) outside along with the unwanted pollutants. 3. Outdoor Air (OA) is introduced to provide fresh air. It is first filtered, then passed through the Lossnay core. This allows it be pre-heated in winter (or pre-cooled in summer) using the energy recovered from the Return Air. 4. Supply Air (SA) then enters your house as fresh pre-heated or pre-cooled air.
