introducing the Lunos ego



LUNOS developed the ego for optimum ventilation with heat recovery in small spaces.


Paired operation is not required*, because in an ego two small fans provide air supply and exhaust air with heat recovery at the same time.


Like the e² systems, the ego uses the principle of regenerative heat exchange. The difference is the ego has two fans in one unit.  The two fans operate in opposite directions so that supply and exhaust air are moved at the same time.


* the system can be switched to an exhaust mode in which an airflow level of 45 m³/h is achievable.


* Please note that prices show are retail only. For commercial pricing please contact a Lunos sales representative.  See Services or Accessories for more information.

Occasionally, items may be out-of-stock or back-ordered. You will be alerted in both instances, and in the event of a backorder, you will be provided an approximate date of shipment.


Please note that we do not ship on Saturdays, Sundays or Canadian holidays.
