Connection Boxes (Plenums) for Diffusers and Grilles
Product Description
Connection boxes (also known as static pressure plenums or adapters) serve as the connecting link between the air duct system and air distribution devices — diffusers or grilles.
The use of such boxes allows to:
- Evenly distribute the airflow before supplying it to the diffuser.
- Reduce air velocity and reduce noise.
- Conveniently connect flexible or rigid air ducts to the ceiling diffuser.
Upon customer request, the interior of the box can be equipped with thermal and acoustic insulation.
