LDL-H 125-75/90 x 2 diffuser connection box

LDL-H 125-75/90 x 2 Diffuser Connection Box (Metal)

Product Description

The LDL-H is a galvanized steel diffuser connection box designed to connect the REC Flex System flexible ducting to air supply or extract diffusers. This box allows for the connection of two flexible ducts to a single Ø125 mm diffuser and offers exceptional flexibility during installation.

Recommended Usage Scenarios

This box is highly versatile and is recommended for the following standard cases:

• For Extra Quiet Operation: When maximum acoustic comfort is desired (e.g., in bedrooms), a flexible AKU Comp silencer can be installed between the LDL-H box and the diffuser.
• Wall Mounting: Ideal when the supply or extract diffuser is to be mounted on a wall.
• Flexible Positioning: When the exact location of the diffuser is not known in advance. You can connect 1-2 meters of flexible Ø125 mm duct to the LDL-H, allowing you to easily select or adjust the precise diffuser location later.

Key Features and Installation

• Design: The box features two spigots for flexible duct connections and one spigot for the diffuser.
• Material: Manufactured from high-quality galvanized sheet metal (ZN 275).
• Airtightness: To ensure a tight connection, it is necessary to use RE 75 or RE 90 rubber gaskets (depending on the duct diameter).
• Compatibility: By using FP 75 or FP 90 connectors, either Ø75 mm or Ø90 mm ducts can be connected to the same LDL-H box.
