Focus on low noise
With the new AM 300, we have set ourselves the challenge of meeting the particularly stringent requirements for low-frequency noise that apply to school buildings in Sweden and Norway, among other places. We have risen to the challenge and believe that the improved low-frequency noise performance is of interest to all our customers. These requirements are simply formulated in Swedish law, in that the C-weighted sound level must not exceed the A-weighted sound level by more than 20 dB, so that at 30 dB(A), a maximum of 50 dB(C) may occur.
Low energy consumption – Ecodesign class A
The new AM 300 still has the low-energy EC motors and an efficient countercurrent heat exchanger with an efficiency of approx. 85%. The unit uses very little energy to transport air and complies with energy class A, cf. Ecodesign.
Focus on airtightness and minimal leakage
Airtightness has been improved on the new AM 300 and complies with:
- class L2, cf. EN 1886:2007 and
- class A1, cf. EN 13141-7:2010.
Airtightness also applies to the newly developed shut-off dampers, which comply with class 3 for shut-off dampers, cf. EN 1751:2014.
