DAU 03 RÉACTIL / DAP 03 RÉACTIL

Product catalog summary

Overview: The document is a technical guide created by France Air in 2010, detailing the specifications and functionalities of the DAU 03 and DAP 03 Réactil circular diffusers with a thermostatic system.

Advantages: The diffusers automatically transition between winter and summer positions without the need for electrical connections, ensuring optimal comfort through automatic adjustment of the diffuser cone.

Designation: The DAU 03 Réactil is identified by its diameter, material (aluminium), and fixing method (screws or false ceiling slab).

Range: The DAU 03 Réactil is available in diameters ranging from 160 mm to 355 mm, while the DAP 03 Réactil is available in diameters from 160 mm to 315 mm, both painted in white RAL 9010.

Application: Suitable for buildings with numerous or hard-to-reach diffusers, such as offices and shops, for heating and air conditioning purposes.

Construction/Composition: Features detachable central cones made of cast-off aluminium and a steel frame for the DAP 03 Réactil.

Options: Available in various RAL paint colors.

Specification: Ceiling diffusers are circular with multicones, adjustable by a thermostatic system for automatic seasonal transitions, made of aluminium, and optionally integrated onto a steel slab.

Technical Description: The document provides detailed dimensions for both DAU 03 and DAP 03 Réactil models, including nominal diameters and positions for hot and cold modes.

Functioning Principles: The thermostatic system adjusts the position of the mobile cones based on air temperature, transitioning to a hot position at 25-28°C and a cold position at 17-24°C, with transition times varying based on airflow.

Performance Data: A selection chart provides data on airflow (m3/h), pressure loss (Pt in Pa), and sound power level (Lw in NR) for different diameters and flow rates, indicating performance in cold mode.

Thermostatic System: The system operates in summer mode with a cold air blade and in winter mode with a hot air blade.
