SpiroFlex wall/floor rosette white Ø150 mm for ventilation duct connection SX-WO150R

SpiroFlex wall/floor rosette white Ø150 mm (model SX-WO150R) is a circular termination flange designed for neat connection of 150 mm ventilation ducts to walls or floors. The rosette provides a finished edge around the duct penetration, helps guide airflow into or out of the ventilation system and improves the visual appearance of duct connections in residential or light commercial installations. Its white finish allows it to blend with common interior surfaces while maintaining functional alignment with circular ductwork.

Advantages

The rosette creates a clean, flush termination for round ventilation ducts and reduces visible gaps at wall or floor penetrations. It facilitates easier connection of ducts and diffusers and supports a more professional appearance of the ventilation outlet. The white surface is durable for indoor use and simplifies finishing around the opening without additional trim. Designed for 150 mm diameter systems, it fits standard round ductwork and helps maintain airflow direction at the connection point.

Suitable for

• Residential ventilation duct terminations with 150 mm round ducts
• Light commercial ventilation where a tidy wall or floor penetration is required
• Connections to circular diffusers, grilles or flexible ducts of matching diameter

Key specifications

• Outer diameter: approximately 150 mm to match circular ducting systems
• Material: rigid plastic with white finish suitable for indoor environments
• Application: wall or floor termination and duct connection for circular ventilation systems
• Compatibility: intended for use with 150 mm round ducts and corresponding fittings
• Mounting: flange-style rosette for visible finishing around duct penetration

How to use

Measure and cut the wall or floor opening to suit the 150 mm duct and insert the rosette so that the flange sits flush with the finished surface. Align the rosette with the circular duct and slide the duct into the opening until it contacts the internal edge. Secure the duct to the rosette and surrounding structure using appropriate clamps or sealants for airtightness where required. Connect any diffuser, grille or flexible duct to the rosette according to the accessory instructions.

Usage recommendations

Ensure surfaces are clean and dry before installation; use suitable sealing tape or silicone if an airtight connection is needed. Verify that the rosette is compatible with existing 150 mm duct components and allow access for future maintenance or diffuser replacement.
