Wall collar airRoxy 100 (model 02-458) for ventilation duct connection

The airRoxy Wall collar 100 (model 02-458) is a compact wall flange designed to connect round ventilation ducts with a 100 mm nominal diameter to building wall openings. It provides a stable mounting point for ductwork, helps maintain alignment of the ventilation pipe and reduces gaps around the penetration to improve sealing. The low-profile design is intended for residential and light commercial ventilation installations where a tidy, space-saving wall transition is needed.

Advantages

The wall collar is made for straightforward installation and provides a secure, flush connection between the duct and the wall. Its compact form minimizes protrusion from the wall while offering sufficient support for attachment and sealing materials. The design supports consistent alignment of circular ducts and reduces the risk of air leakage at the wall interface when installed with appropriate sealing.

Suitable for

• Connecting round ventilation ducts with 100 mm nominal diameter to exterior or interior walls
• Residential bathroom, kitchen or utility room ventilation systems
• Light commercial or small office ventilation where a compact wall transition is required

Key specifications

• Compatible duct nominal diameter: 100 mm
• Function: wall flange / collar for ventilation duct connection
• Profile: low-profile design for minimal wall protrusion
• Typical application: wall penetration support and sealing of round ducts

How to use

Cut or prepare a wall opening sized to accommodate the collar and the 100 mm duct. Insert the collar into the wall opening and align the duct so it seats securely into the collar. Fasten the collar to the wall using appropriate screws or fixings for the wall material. Apply suitable sealing material around the collar and duct joint to ensure an airtight connection and to prevent moisture ingress. Verify alignment and secure attachment before completing the interior and exterior finishes.

Usage recommendations

Use compatible 100 mm round ventilation ducting and recommended sealing products. Select fixings appropriate for the wall substrate and check that the collar is flush and aligned before sealing. For external wall terminations, use additional weatherproofing as required by local building practice.
