System features

PP 45/PPB 30 are ventilation units with heat recovery (HR). In heat recovery mode, a ceramic heat exchanger stores the heat from the exhaust air flow.

This heat is then transferred to the passing supply air entering the rooms – heated air flows into the rooms. The ventilation system should be switched on permanently.

The fan unit is designed as a slide-in module and can be removed for cleaning or to change the filter (PP 45).
