Intended use

PP 45 ventilation units with heat recovery are used for air extraction/ventilation of apartments, offices or similar rooms. They are suitable for new buildings and renovation work. The units are designed for 24h operation. The housing unit’s ventilation system should be configured in accordance with DIN 1946-6.

PP 45 are ventilation units, which are generally only suitable for use in supply air rooms. To achieve efficient ventilation of these units, we would recommend operating the PP 45 in pairs, with alternating ventilation and air extraction.

The units are installed in exterior walls (wall thickness 265-790 mm) The electrical connection is made to a permanent electrical installation.

The ventilation units are operated using a room air control suited to the unit type:

Control RLS 45 O or RLS 45 K
for PP 45 O / PP 45 K and PPB 30 O / PPB 30 K.
Radio switch DS 45 RC for PP 45 RC /
PPB 30 RC.
Alternatively, with RLS 45 K + radio extension module PP 45 EO.
