Product catalog summary

Product Description: The DFRE-P is a swirl diffuser designed for risers, manufactured by KOOLAIR. It is available in various sizes and is integrated into a plate with customizable dimensions. The diffuser is constructed from steel sheet and can be painted in any RAL color upon request. An alternative model, the DFRE-P-C, is available with a circular plate.

Mounting Options: The diffuser can be mounted directly using a mounting bridge (PM) or connected to a plenum box made of galvanized steel sheet (PD). Design details for the plenum box are available upon consultation.

Technical Specifications: The document provides a legend explaining key parameters: Q (m3/h) for air flow, ∆Pt (Pa) for total pressure loss, LwA [dB(A)] for sound power level, and VX (m/s) for maximum air stream velocity at 0.70 m from the diffuser.

General Dimensions: The nominal dimensions for various sizes are provided, with measurements in millimeters. For example, a nominal size of 100 has dimensions Ø127/125, 115, and 99 mm for A, B, and D respectively.

Performance Data: A table outlines performance data for different sizes, including air flow (Q), sound power level (LwA), total pressure loss (∆Pt), and maximum velocity (Vx). For instance, a size 100 diffuser with an air flow of 30 m3/h has a sound power level of 20 dB(A), a pressure loss of 10 Pa, and a velocity of 0.08 m/s.

Selection Table: The document includes a selection table for the DFRE-P and DFRE-P-C models, detailing dimensions such as ØA, ØD, and ØB.
