Intended use

PP 45/PPB 30 units with heat recovery are used for air extraction/ventilation of apartments, offices and 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 suited to 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. We recommend multiple ventilation units per room for larger residential units. PP 45 units are available in the following models: "O" for object, "K" for comfort and "RC" for radio-controlled.

PPB 30 are balanced ventilation units, which are the ideal choice for use in exhaust air rooms (bathroom, WC or kitchen with windows) and ventilate and extract air from the rooms at the same time. Exhaust air mode is started automatically depending on the setting or can be started manually at the touch of a button. PPB 30 are stand-alone units or can be used in groups with other PPB 30/PP 45 units. They can also be used in damp rooms (protection zone 1). Combinations of PPB 30 K units with exhaust air units (e.g. ER/ECA) are not possible.

PP 45 units are fitted in exterior walls, with a wall thickness of 265-790 mm; PPB 30 in exterior walls with a wall thickness of 320-790 mm. The ventilation units are connected to a permanent electrical installation. The ventilation units are operated using a room air control suited to the unit type:

• RLS 45 O for PP 45 O / PP 45 K and PPB 30 O.
• 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 and PPB 30 RC, alternatively with PP 45 K + radio extension module PP 45 EO.
• Combinations of PPB 30 K with PP 45 O are not possible.

An external cover PP 45 AK/AE/AW/AS is mandatory for PP 45 units (see accessories) with integrated condensate drip edge. Alternatively, a combination with the PP 45 LE soffit element is permissible (condensate drain via the drip edge-external grille).

An external cover PPB 30 AK/AE/AW/AS is mandatory for PPB 30 units. These external covers divert the condensate via the side grille.

PP 45/PPB 30 units are only intended for domestic use and similar purposes. No other or additional use is intended.
