Adapter SpiroFlex 60/100 TWK white – SpiroFlex SX-TD60ATWKB

SpiroFlex 60/100 TWK white adapter (SpiroFlex SX-TD60ATWKB) is a duct transition piece designed to join a 60 mm inner duct to a 100 mm outer duct in ventilation systems. Manufactured for use in residential and light commercial HVAC installations, the adapter provides a stable mechanical connection and helps maintain airflow between differing duct diameters. The white finish integrates with typical interior installations and supports standard flexible and rigid duct materials.

Advantages

The adapter delivers a reliable diameter transition with a design that ensures a secure fit between 60 mm and 100 mm ducts. Its construction is intended to minimise air leakage at the junction and to simplify installation where a change of duct size is required. The white colour provides a neutral appearance for visible sections, and the component is compatible with common ventilation materials used in domestic and small commercial systems.

Suitable for

• Connecting 60 mm inner ducts to 100 mm outer ducts in HVAC systems
• Residential ventilation installations such as bathrooms, kitchens, and utility rooms
• Light commercial ventilation where a compact 60/100 transition is required
• Retrofit projects that require restoring or adapting existing ductwork

Key specifications

• Function: Diameter transition adapter for ventilation ducts
• Inner diameter side: 60 mm (connection to smaller duct)
• Outer diameter side: 100 mm (connection to larger duct)
• Colour: White finish suitable for visible installations
• Application: Compatible with flexible and rigid ventilation ducts

How to use

Install the SpiroFlex 60/100 TWK adapter by sliding the 60 mm duct onto the smaller end and the 100 mm duct onto the larger end, ensuring each connection is fully seated. Secure each duct end with appropriate clamps or tape to prevent displacement and to reduce air leakage. Check alignment and clearance within the installation space to avoid bending or compressing the ducts near the transition. Follow local ventilation codes and best practices for sealing and mounting.

Usage recommendations

Inspect duct materials for damage before installation and use corrosion-resistant clamps or approved sealing methods to maintain airtightness. Avoid sharp bends immediately adjacent to the adapter to preserve airflow efficiency and reduce noise. For systems with specific flow or pressure requirements, verify compatibility with system design parameters and consult installation guidelines for the overall ventilation setup.
