Wall diffusers allow the supply air of ventilation and air conditioning systems to flow into the room, with ceiling influence or directly. The airflow occurs with a high induction of the room air. This quickly reduces the air velocity and the temperature difference between supply air and room air. The result is a mixed ventilation system for comfort areas with good room air circulation and low turbulence in the occupied zone. The wall diffusers are equipped with a removable front plate. The front plate contains front rails type PURELINE, which are supplied with factory-set air control blades. The air control blades can be adjusted manually on site. The different airflow directions allow adaptation to different local conditions at any time. The supply air to room air temperature difference may range from -10 to +10 K. To increase transmission loss and reduce sound transmission into adjacent rooms, the diffuser can optionally be equipped with splitters in the plenum box. Damper blades (optional) in the spigot enable the volume flow rate to be balanced during commissioning. The damper screen is adjusted via the opening for the diffuser face. Alternatively, the wall diffuser CHM can also be pre-equipped for combination with a volume flow limiter VFL. The volume flow limiter is set according to the local system parameters and can be mounted from the room side via the opening for the diffuser face. For an architecturally uniform design, the CHM type can be used as an extract air diffuser or also as a supply and extract air combination.
Specification text
Wall diffusers as supply or extract air diffusers, or as supply and extract air combination, for the supply and extraction of air in ventilation and air conditioning systems. Consisting of a plenum box with spigot for connection to the on-site duct system and a removable front plate. Extract air variants are also available without spigot or without a connection option to the on-site duct system. The front plate serves as a carrier for the front rails, which are integrated into the front plate. Air is directed into the room via manually adjustable air control blades which are integrated into the front rails. The airflow with ceiling influence or direct air flow into the room can be preset at the factory. Optionally, splitters are available for improved cross-talk sound attenuation (can be removed from the room side). In addition, the wall diffusers can also be optionally extended with a finely adjustable volume flow limiter in round design.
