Heat Recovery VentilatorLG Air Conditioning

Key Features

High efficiency heat exchangerEfficiency and comfort is ensured by the high-efficiency energy recovery central core which recovers energy from the indoor air and transfers it to the fresh incoming air without mixing airstream.

Bypass ventilationIt switches automatically the ventilation mode (Enthalpy Heat Exchange Mode / Bypass Mode) according to the indoor/outdoor temperature.

Strong filter functionThe air filter has collection efficiency above 80%, which means it can filter particles up to 0.3 m including tobacco of smoke and even floating particles from yellow sand.

Flexibility of installationIt’s possible to install the opposite direction of upper and lower part. It needs the only one inspection hole.

Easy cleaning and changing filterDoor attached side panel and slide removable Enthalpy heat exchanger filter can be changed without additional maintenance.
