Highly efficient motors with state-of-the-art electric technology in combination with mechanical-flow, reworked and especially balanced fans have almost eliminated the known ventilation noises. With a total of less then 16 dB (A)* in level 1,  As comparison: 3 dB decrease stands for 50 % less sound intensity. A ventilator that just complies with this standard is therefore 16 times as loud.Once again new standards set in matters noise.

Environmentally friendly

With a specific fan power of 0.09 W/m3/h the e2 mini is second to none in matters of energy efficiency and thus contributes actively to environmental protection and at the same time spares your purse. The requirements of the current DIN 1946-6 for devices of the efficiency class E are undercut by far which clearly underline the world class of the device.


The e2 mini operates according to the known principle of regenerative heat exchange which has almost been developed to perfection by the company LUNOS. The so-called AcuVent storage stone is located in the middle of the airflow of an electric motor with axial fan. By a reversing airflow, which results for the targeted change of direction of the fan, the ceramics are charged with heat-energy that is offloaded into the room air and discharged again to the air added from outdoors. This is carried out so effectively that a mere 10 % of the heating energy is lost by the ventilation. Efficient filters are just as important. Allergy patients can take a deep breath, pollen and airborne particles can no longer enter the living areas.


The e2 mini is the smallest roomwise apartment ventilation device with heat recovery and is based on the principle of regenerative heat exchange. With the help of state-of-the-art manufacturing processes it has been possible to develop a compact heat exchanger from a ceramic composite material which supplies a thermal efficiency factor of approx. 90.6 %. The combination with highly efficient electric motors and an intelligent control has made it possible for LUNOS to develop one of the most economical ventilators.


The e2mini can be inserted through the outlets/passages of the esisting 100mm ducting.


In a new building, as in a renovated building, the LUNOS e2 mini can be used. The e2 mini is either installed in a new building with the help of a wall recess casing position between the stones, or subsequently, e.g. when renovating with the help of a 100 mm large core bore. The wall need only be a minim 30 cm thick. The cabling is effected directly from the control which is installed in the appertaining flushmount pattress. From there only three leads of cable are required which are charged with 12 V extra low voltage.
