Leading plumbing and drainage manufacturer Wavin expands its Mechanical Ventilation Heat Recovery solutions with the launch of the new Ventiza FlexPro-90, a higher-capacity semi-rigid radial duct developed to meet the increased airflow demands of modern, energy-efficient homes.
The new 90mm duct builds on the Ventiza FlexPro‑75 system introduced last year, delivering up to 45% more airflow than standard 75mm options at the same velocity levels – enabling installers to achieve required ventilation rates using fewer ducts.
The increased airflow capacity lowers the back pressure and enables MVHR units to operate at lower speeds, helping to reduce energy consumption and lower system noise for homeowners.
Supplied in continuous 50‑metre coils, the new semi-rigid radial duct reduces the number of joints required, supporting simpler installation and minimising air leakage risk.
The duct’s double‑wall construction includes an insulating air void to support improved acoustic and thermal performance, contributing to quieter operation within the home. The material also incorporates antibacterial, antifungal, and antistatic properties to help maintain air‑quality standards and reduce dust build‑up inside the system over time.
Features of the Ventiza FlexPro range include a smooth internal surface designed to reduce air resistance, and a ribbed exterior providing high mechanical strength and impact resistance suitable for on‑site conditions.
FlexPro‑90 is available now, with a full range of connectors to be introduced in May. The duct has been designed to remain compatible with existing connectors on the market, so ongoing projects can adopt the new system without delay.
Ben Perris Sales Director for Indoor Climate Solutions for Wavin said: “The launch of FlexPro‑90 is a great example of our commitment to giving installers and developers the flexibility they need to design high‑performing, future‑ready ventilation systems in action. Its increased airflow capacity supports the growing demands of modern, energy‑efficient homes, while helping installers create simpler, more efficient systems with less noise and lower energy use.”
Alongside the new Ventiza FlexPro range, Wavin’s online Ventilation System Finder supports early‑stage project design by helping built environment professionals identify the correct ducting configuration and suitable MVHR unit for their specification.
Following system selection, Wavin’s technical team works directly with developers and installers throughout design and installation, helping to ensure accurate system performance and smoother project delivery.
