Aldes W16 BDH 5/30 11015131: Hygrorégulable Ventilation Grille

Product Overview

The Aldes W16 BDH 5/30 (Model 11015131) is a hygrorégulable extraction grille designed for sanitary rooms such as bathrooms and WCs. It ensures efficient and continuous extraction of indoor pollutants by automatically adjusting airflow based on the room's humidity level.

Key Product Features

• Simplified maintenance with a removable face
• Unique design without an external grille
• Roll-in seal for enhanced airtightness

Operating Principles

In a hygrorégulable VMC (Mechanical Ventilation Controlled) system, airflow is automatically regulated according to room humidity. The BDH grille is installed in sanitary rooms to meet the building's ventilation needs.

Product Description

The BDH grille is ideal for technical rooms in individual homes and collective housing, suitable for both new builds and renovations. It is a compact hygrorégulable grille designed for flow rates below 50 m³/h.

Application Areas

• Collective Residential Housing
• Individual Residential Housing
• New Construction
• Renovation

Installation Guidelines

• Install the BDH grille in humid or technical rooms like bathrooms, WCs, or utility rooms.
• Position the grille at the upper part of a vertical wall or on the ceiling, at least 1.80 meters above the floor.
• Ensure the grille is accessible and removable, with at least 20 cm clearance from adjacent walls and not flush with the duct.
• Optimal airtightness of the grille-duct connection is crucial, improved by using a sleeve. A metal sleeve is required for collective housing (stainless steel for Gas VMC), while a plastic sleeve is suitable for individual homes.
• Grilles with a Ø 125 mm duct attach directly (push-fit with O-ring) into sleeves, RT Flex, or rigid/semi-rigid ducts.
• Grilles with a Ø 80 mm duct attach by push-fit into sleeves or rigid/semi-rigid ducts.
• For cord-controlled grilles installed on the ceiling or above furniture, use a [cord-return] symbol.
• For electrically controlled hygrorégulable grilles, two AA/LR06 batteries and a standard push-button [push-button] symbol are required.
• Hygrorégulable grilles operate within a pressure range of 80-160 Pa.
• Extraction grilles require annual maintenance and checks. Connecting a mechanical hood to the VMC system is prohibited (Art. 14 - decree of March 24, 1982).
• Before replacing an old grille, perform a pressure reading and note the housing type.
