Roof exhaust vent SpiroFlex SpiroFlex 60/100 turbo with roof plate (model SX-TDN60/100WPD)

SpiroFlex 60/100 turbo roof exhaust vent (model SX-TDN60/100WPD) is a roof-mounted ventilation terminal designed to connect duct systems with a 60 mm to 100 mm transition. Supplied with a roof plate for secure installation on pitched roofs, this unit combines a turbo-style outlet with a stepped connection to accommodate both smaller and larger round ducts. It is intended for extraction of moist or stale air from residential and light-commercial ventilation systems and for use where a compact roof-mounted terminal is required.

Advantages

The SpiroFlex 60/100 turbo vent provides a compact roof terminal with a built-in transition between 60 mm and 100 mm duct sizes, reducing the need for additional adapters. Its roof plate ensures a stable, weather-resistant mounting on pitched roofs while maintaining a low profile to minimize visual impact. The turbo-style outlet supports efficient exhaust airflow and helps reduce backflow and ingress of precipitation when correctly installed. Materials and form factor are chosen to simplify connection to round ductwork and to speed up on-site installation.

Suitable for

• Extraction of moist air from bathrooms, kitchens, and utility rooms
• Ventilation exhaust in small residential and light-commercial buildings
• Connection to round ducts requiring a 60 mm to 100 mm transition
• Replacement or upgrade of existing roof terminals on pitched roofs

Key specifications

• Connection transition: fits round ducts with diameters from 60 mm to 100 mm
• Mounting: supplied with a roof plate for pitched roof installation
• Outlet type: turbo-style exhaust outlet for improved airflow
• Application: extraction of moist or stale air from ventilation systems
• Compatibility: suitable for residential and light-commercial ducted ventilation

How to use

Mount the roof plate securely to the pitched roof structure following local building and weatherproofing requirements, ensuring correct sealing around the opening. Connect the appropriate size round duct (60 mm or 100 mm) to the stepped connection and secure with appropriate clamps or sealant to prevent air leaks. Position the turbo outlet above the roofline so exhaust air is discharged freely; check the orientation and clearances recommended for roof terminals. After installation, verify airflow and check for any signs of vibration, leakage or unwanted ingress.

Usage recommendations

For reliable long-term performance, ensure the vent is installed by a qualified fitter and inspected periodically for debris buildup, seal integrity, and secure mounting. Use corrosion-resistant fasteners and suitable flashing materials compatible with the roof covering to maintain weatherproofing.
