FLX-PVC-SRGL Extension Pipe for Alnor Plenum Boxes
FLX-PVC-SRGL
FLX-PVC-SRGL: Extension Pipe for Air Valve Plenum Boxes (FLX-PLO-EPP)
The FLX-PVC-SRGL is a dedicated PVC extension piece designed to solve a critical installation challenge: accommodating the depth of thick ceilings or walls. This round pipe component extends the air valve connection spigot (d1) found on Alnor FLX-PLO-EPP-F plenum boxes, ensuring a clean and secure fit for both supply and extract air valves.
Technical Specifications and Dimensions for Installers
Understanding the material and precise dimensions is essential for a seamless integration with the main FLX-REKU components.
Material: The pipe is constructed from durable PVC.
Standard Length: Each extension piece is supplied in a length of 500mm (0.5m).
Wall Thickness: The pipe maintains a wall thickness of 1.5mm, providing structural integrity while remaining lightweight.
Available Diameters: The extension pipe is available to match the common plenum box outlet sizes:
FLX-PVC-SRGL-100-0050: Diameter 100mm
FLX-PVC-SRGL-125-0050: Diameter 125mm
Installation Instructions and Required Accessories
Proper installation ensures airtightness and a professional finish for the air valve connection.
Step-by-step connection:
Attach Coupling: A separate coupling, either FLX-PVC-NS-100 or FLX-PVC-NS-125, is required to securely install the extension pipe onto the FLX-PLO-EPP-F plenum box.
Fixation: It is highly recommended to fix the male coupling (which connects to the plenum box) with steel screws to ensure a robust, permanent attachment before mounting the extension pipe.
Air Valve Installation: The air valve mounting frame should be attached to the extension pipe using either steel screws or a polymer-based mounting adhesive for the final seal.
This dedicated accessory ensures that the high airtightness class (ATC2 D) of the overall FLX-REKU system is maintained even when adapting to thicker ceiling finishes.
