Square and rectangular louvered face ceiling diffusers are an excellent option in HVAC systems that require high indoor comfort levels, clean air quality, and precise airflow performance. These diffusers are purpose-built for ceiling installations and function efficiently for both supply and return air. Their design creates a uniform airflow pattern through multiple concentric sections.
They provide consistent air distribution, balanced airflow, reduced noise, appealing aesthetics, and durable construction—making them a reliable choice for many architectural and engineering applications.
These diffusers are capable of delivering a wide range of horizontal airflow patterns suitable for various HVAC design conditions while maintaining an attractive appearance that blends well with most ceiling layouts.
Opposed-blade dampers can also be added to transform the diffuser into a unit capable of controlled air volume regulation.
