Durable construction for long-term reliability
The Kensington Inline Draft Blocker 100mm is a practical and efficient solution for maintaining optimal airflow while protecting your ventilation system from unwanted backflow. Designed specifically for installations where rangehood ventilation exhausts out through the roof, this draft blocker ensures that air only travels in one direction—outwards.
At the core of its design is a spring-loaded internal butterfly damper, engineered to respond to airflow dynamically. When the rangehood is in use, the damper automatically opens to allow proper ventilation. Once the system is turned off, the damper closes securely, preventing external air, debris, and pests from entering your home through the ducting.
Constructed with durability and functionality in mind, the Kensington Inline Draft Blocker helps improve energy efficiency by reducing heat loss and eliminating drafts. It’s an ideal upgrade for any kitchen ventilation setup, particularly in cooler climates where temperature control and airflow management are essential.
This unit is easy to install and designed to integrate seamlessly into most 100mm ducting systems, making it a dependable choice for both new constructions and retrofit projects.
