ego is equipped with highly efficient motors with the latest ec technology. In combination with flow-mechanically reworked and specially balanced fans, the well-known air noises have been virtually eliminated. This results in low measuring surface sound pressure levels.
With a very low power consumption, the ego is unsurpassed in energy efficiency and thus makes an active contribution to environmental protection and also saves money. The requirements of the current DIN 1946-6 for devices in efficiency class E are undercut many times over.
The ego works like the e² according to the well-known principle of regenerative heat exchange, which has been almost perfected by LUNOS. The novel ceramic with hexagonal honeycomb structure sits in the middle of the air flow of two ec motors with axial fan. By means of reversing and counter-rotating air flows, which are created by a targeted change in direction of the fans, the halves of the ceramic charge themselves with the heat energy of the room air or release it to the outside air supplied. This happens so efficiently that less than 15 % of the heating energy is lost through ventilation. Equally important are efficient filters. Allergy sufferers can breathe a sigh of relief; with the optional pollen filters, pollen, dirt and suspended particles can no longer enter the home.
The ego is one of the smallest decentralised fans for domestic ventilation with heat recovery. With the help of the most modern manufacturing processes, it has been possible to develop a compact heat accumulator made of a ceramic composite material, which delivers a thermal efficiency of up to 87.7 %.
