AirVital PRIME decentralized ventilation is a highly efficient flush-mounted system for single rooms and small apartments. An incredible 94.5% heat recovery is achieved by minimizing ventilation heat loss using an innovative cross-counterflow heat exchanger. The intelligently controlled ventilation system, well thought-out in every respect, also impresses with extremely low power consumption. This reduces annual energy costs to the equivalent of a few cups of cappucino at the cafe. Optimized sound insulation ensures whisper-quiet operation. Protection from mold, aerosols, allergens and pathogens, as well as from strong winds and frost, is provided by efficient filters and flap systems.
