Plenum Box for Round Ceiling Diffusers
Connection Box for Even Air Distribution & Easy Installation
The Plenum Box for Round Ceiling Diffusers is designed to provide a stable and efficient connection between the duct system and ceiling diffuser. It helps regulate and distribute airflow evenly, improving overall system performance while simplifying installation.
Specifically suited for use with round ceiling diffusers, these plenum boxes are commonly used in ventilation systems where controlled air distribution and a clean ceiling finish are required.
What is a Plenum Box?
A plenum box is a connection chamber fitted behind a ceiling diffuser. It acts as a transition point between the ductwork and the diffuser, helping to balance airflow and reduce turbulence before air enters or exits the room.
How Does It Work?
Air enters the plenum box from the connected ducting and is evenly distributed across the diffuser face. This helps to improve airflow patterns, reduce noise, and ensure consistent air delivery throughout the space.
