Perforated Plates

Perforated plates are used in HVAC systems to supply or extract air through a perforated face, helping to distribute airflow evenly across a space. The perforation pattern reduces air velocity at the grille face, which helps achieve a more uniform air distribution and improves comfort levels within the room.  

They are commonly used as both supply air diffusers and extract grilles, depending on the system design. In supply applications, perforated plates help spread conditioned air gently into the space. In extract applications, they allow air to be drawn back into the system while maintaining a clean, unobtrusive finish.  

Our collection includes perforated plate grilles and perforated plate diffusers for use in ceilings and walls across commercial and industrial HVAC installations. Typical applications include offices, schools, hospitals, retail spaces and other buildings where controlled air movement and a minimal visual impact are required.
