SpiroFlex double-wall duct pipe 80/125 mm white 0.5 m, model SX-TD80/125RB0,5

SpiroFlex double-wall duct pipe 80/125 mm, white finish, length 0.5 m is a rigid concentric ventilation and exhaust component designed for installations that require an inner 80 mm airway and an outer 125 mm protective sleeve. The product provides a separated concentric path for supply or exhaust air and is intended for indoor or sheltered locations where a two-wall configuration helps maintain airflow integrity and prevents direct exposure of the inner airway to surrounding conditions.

Advantages

The double-wall construction offers mechanical protection for the inner duct while maintaining a compact concentric layout. The white finish delivers a neutral appearance suitable for visible or semi-exposed installations. Rigid materials ensure dimensional stability, simplified alignment during assembly and reduced risk of deformation compared with flexible ducts. Short length facilitates use as a modular connector between fans, flue terminations and larger duct sections.

Suitable for

• Concentric ventilation connections where inner and outer diameters of 80 mm and 125 mm are required
• Extractor fan outlets that need a protected exhaust path
• Flue or appliance venting in sheltered or indoor spaces
• Modular HVAC assemblies requiring short rigid transition pieces

Key specifications

• Inner diameter: 80 mm
• Outer diameter: 125 mm
• Length: 0.5 m
• Color/finish: white
• Construction: rigid double-wall (concentric) duct
• Intended installation: indoor or sheltered locations

How to use

Install the pipe as a concentric transition between compatible components so that the 80 mm inner airway aligns with the appliance or fan outlet and the 125 mm outer sleeve connects to the receiving duct or termination. Use appropriate joining collars, clamps or sealants rated for ventilation systems to ensure airtight connections where required. Support the assembly according to local installation rules and avoid exposing the component to direct outdoor weathering or contact with high-temperature surfaces beyond its specified application.

Usage recommendations

Verify compatibility with the connected fan, flue or ventilation components before installation. For safe and efficient operation, follow applicable ventilation and building regulations, maintain clearance from heat sources, and perform periodic inspections to check joints and supports.
