76mm (3") ID Aluminium Flexible Air Duct for Cooker Hood, Air Conditioner, Extractor Fan, Tumble Dryer - 2m / 6.5ft Semi-Rigid Exhaust Hose - Ventilation Ducting

Aluminium semi-flexible air ducting is a type of duct work commonly used in heating, ventilation, and air conditioning HVAC systems. It is made from aluminum, which makes it lightweight and flexible, allowing for easy installation in various applications. Ducts are designed for flexible connections between specific ventilation system components, e.g. the main ventilation ducts and plenum boxes. They can also be used for hot air exhaust connections between fireplace fireboxes and for building air heating duct work. Round ducting has the most effective airflow performance and should be considered as the first option, if space will allow. Connects to extractor fans, cooker hoods and other diameter systems. The use of aluminum in the construction of the ducting provides a balance between flexibility and durability. Aluminum is resistant to corrosion, which is important for HVAC systems where the ducting may be exposed to different environmental conditions. This type of ducting is not as rigid as traditional ducts, offering some degree of flexibility. It can be bent and shaped to accommodate the specific layout and requirements of the HVAC system. While aluminum is generally resistant to temperature variations, it's essential to ensure that the specific ducting used is suitable for the temperature range expected in the HVAC system. The interior surface of the ducting is typically smooth, promoting efficient airflow. However, care should be taken during installation to avoid sharp bends and kinks that could impede airflow. The flexibility of the ducting makes it relatively easy to install, especially in situations where rigid ducts might be challenging to fit. However, care should be taken to avoid sharp bends that could restrict airflow.
