Lunos e² – home ventilation with heat recovery for all application purposes, can be used even for high sound protection requirements.

With a very low energy consumption, super silent and extremely compact, the Lunos e² units achieve very good energy-efficiency – class A, and provides a heat recovery rate of up to 90 %.

• Certification Z-51.3-242

• RoHS and WEEE compliant

• Tested according to DIN 308 and DIBT Standard

• EnEV and DIN 1946-6 compliant

• Used in low energy houses

Technology – low noise level

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 16 dB in level 1, 19.5 dB at level 2 and 26 dB at level 3 (each 17, 32 or resp. 38 m3/h volume throughput) the fans are well below the required values of DIN for living and sleeping rooms.

As a 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.

Advantages

• Environmentally friendly - Efficiency

With a specific fan power of 0.09 W/m3/h, Lunos e² is second to none in matters of energy efficiency and thus contributes actively to environmental protection and at the same time spares your purse. 

• Healthy indoor environment

Efficient filters are just as important. Allergy patients can take a deep breath, pollen and airborne particles can no longer enter the living areas.

• Innovative – Heat Recovery

Lunos e² operates according to the known principle of regenerative heat exchange. The so-called AcuVent storage stone is located in the middle of the airflow of an electric motor with an 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 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 intelligent control has made it possible for LUNOS to develop one of the most economical ventilators.

• Slim - Small dimensions

The e² is the smallest decentralised fans on the field of home ventilation with heat recovery. Like the e²neo, the 160 fans e² and e²short are extremely compact in their volume flow class.

• Compatibility with other devices

If a LUNOS ventilation system has already been installed, an existing fan of the 160 series can be replaced by the fans e² and e²short. This is possible by the use of the same wall duct. In a new building the LUNOS e² can also be combined with all LUNOtherm elements.

• Versatile installation option

In a new building, as well as in a renovated building, all fans of the LUNOS e² series can be used. The e² 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 162 mm large core bore.
