Zehnder ComfoTube ø110mm Semi-Rigid Ductwork – High-Performance, Airtight & Easy-to-Install dMEV Ventilation Solution

Zehnder ComfoTube ø110mm is a semi-rigid ducting system designed specifically for residential decentralised mechanical extract ventilation (dMEV). Its robust, smooth internal lining reduces dust build-up, simplifies maintenance, and ensures optimal air quality. With fewer connections and advanced sealing technology, installation is fast, airtight, and reliable, resulting in reduced noise and lower running costs.

• Rapid Installation: Significantly quicker and easier installation than conventional ducting, minimising connections and air leakage.
• Airtight Connections: Integrated O-rings and locking slides ensure airtight seals, preventing accidental disconnection during first fix.
• Easy Maintenance: Clinically smooth internal lining for reduced dust accumulation and simple cleaning.
• Hygienic System: Optional end caps available to prevent dust ingress during construction.
• Durable Construction: Crush-resistant with ring stiffness >8 kN/m², corrosion-resistant, and suitable for embedding in concrete structures.
• Fully Accredited: Approved and listed on the Product Characteristics Database (PCDB) for reliable compliance.
• Material Quality: Manufactured from high-quality food-grade polyethylene (PE), lightweight, corrosion-resistant, and easy to handle.
