PremAir Units

Heat recovery ventilation unit HRU-PremAIR is a modern device with 350 / 450 or 500 m3/h airflow @ 100 Pa. The unit is made from cutting edge materials – PET or aluminum heat exchanger and EPP self-supporting casing. Depending on the model, the following heat exchangers are used: counterflow heat exchanger made of PET, aluminum heat exchanger or counterflow, enthalpy exchanger.

Enthalpy exchangers in HRU-PremAIR-E series have a polymer membrane that effectively recovers heat and moisture from the extract air. Such membrane works like a membrane in waterproof trekking clothing i.e. it allows water vapour to pass through, but not liquid water and air. The enthalpy exchanger also blocks the transfer of odours, bacteria, and spores.

HRU-PremAIR-450 is certified by Passive House
Institute and can be used as a certified
component in passive houses.
