Intended use

PP 45 / PPB 30 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 PP 45 units, we would recommend operating the PP 45 in pairs, with alternating ventilation and air extraction. The PP 45 exists in unit variants O, K andRC.

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 standalone units or can be used in groups with other PPB 30/PP 45 units. The PPB 30 exists in unit variants O, K andRC. They have degree of protection IP X4. The protection zone must be determined depending on the unit variant used.

PP 45 are installed 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 electrical connection is made to a permanent electrical installation.

The fan/heat exchanger unit is designed as a duct mounting and can be removed for repair and cleaning purposes.

A PP 45/PPB 30 external cover with integrated condensate drain is required for installation with a wall sleeve. For PP 45 , installation in the window soffit with the PP 45 LE soffit element is permitted as an alternative.

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