Watertight ABS Duct Fan Hose Wall Connector — 100mm and 150mm Key benefits Creates a watertight, secure connection between the wall and duct/vent to prevent air and moisture leakage. Reduces loss of extracted air, improving extractor fan efficiency and overall ventilation performance. Durable ABS construction for longlasting use in indoor ventilation systems. Features Material: Robust ABS plastic that resists everyday wear in ventilation installations. Sizes: Available in 100mm and 150mm diameters to match common duct and vent sizes. Installation: Designed for easy, hassle wall mounting; quick to install and saves time on site. Function: Connects inline fans, flexible hose, and wall vents to create a sealed transition that minimizes leakage and backflow. Compatibility and performance Fits standard 100mm or 150mm ducts, vents, and fan hoses — choose the size that matches your existing system. Improves airflow efficiency by sealing the joint between the fan hose and wall vent, helping the fan work more effectively. Provides a neat, stable connection that reduces vibration and movement at the duct joint. Practical applications (use scenarios) Bathroom extractor fan: Connects the fan hose to the external wall vent to ensure moisture and odors are expelled without leakage into the cavity. Kitchen ventilation: Seals the ducting for a kitchen exhaust fan or hood to maintain airflow efficiency and reduce greaseladen air escaping into the wall. Laundry or utility room: Links inline fan ducting to a wall outlet to keep humid air moving outside and protect surrounding structures. Why choose this connector Simple, reliable solution for sealing fan hosetowall connections. Two size options for direct compatibility with common ventilation setups. Solid ABS construction balances durability with easy handling and installation. What's included One ABS wall duct fan hose adapter in the selected size (100mm or 150mm).
