Product catalog summary

Product Description: The DFRE-C-PR is a fixed blade swirl diffuser with a perforated plate, designed for air supply and return. It features a removable perforated plate and a fixed swirl diffuser, offering easy access and maintenance.

Applications: This diffuser is ideal for environments requiring high air supply flow rates and low velocities, while maintaining aesthetic integration with interior design. Its high induction rate helps reduce air velocities and improve thermal gradient conditions in occupied zones. Recommended installation height is between 2.5 to 3.5 meters, with a spacing of 2 to 4 meters between diffusers, depending on airflow.

Specifications: The standard finish is RAL 9010, with special finishes available upon request. The diffuser is available in various sizes, each with specific dimensions and performance characteristics.

Performance Data: The quick selection table provides data on air flow, sound power, and pressure drop for different sizes, ranging from 125 to 500. For example, a size 125 diffuser has an air flow of 28 m3/h at 20 dB(A) with a pressure drop of 4 Pa.

Dimensions: The document includes a detailed table of dimensions for each model size, specifying measurements such as ØA, ØB, ØC, and D.
