The Kensington Inline Draft Blocker 150mm is a practical and reliable solution for maintaining the efficiency and cleanliness of your home’s ventilation system. Specially designed to prevent unwanted backflow, this draft blocker is ideal for use in kitchen rangehoods that exhaust through the roof. Its robust construction features an internal spring-loaded butterfly damper, which responds dynamically to airflow. When the rangehood is in use, the damper opens to allow effective ventilation; when not in use, it closes tightly to stop outside air, debris, insects, or unpleasant odours from entering the ducting.
This smart mechanism not only improves indoor air quality but also supports energy efficiency by helping to maintain indoor temperature control, especially in homes using climate control systems. The 150mm size makes it compatible with most standard ducting systems, ensuring a straightforward installation for both professional installers and competent DIYers. Whether you're upgrading an existing system or building new, the Kensington Inline Draft Blocker is a dependable addition to your ventilation setup.
