Aluminium Semi-Rigid Duct Hose (ALH) is a flexible, extendable, and reliable solution for HVAC, ventilation, and industrial air ducting needs. Aluminium Semi-Rigid Duct Hose (ALH) Description Phoenix “ALH” Aluminium Semi-Rigid Air Ducts are flexible, extendable, and highly reliable for low to medium pressure air conditioning, ventilation, boiler systems, and chimney liners. This flexible air duct is elastic and stretchable and can be compressed for easy storage. Oval and Circular Connectors can be easily installed on this hose. Aluminium Semi-Rigid Air Duct is an industrial ventilation hose that withstands high temperature. The ALH Duct Hose is secured with an “Interlock” Crimp System, minimizing the risk of separation when stretched or bent. Applications HVAC Ducting: Commonly used in HVAC ducting systems for heating, ventilation, air conditioning, exhaust, and return air ducts. Industrial: For fume extraction, dust collection, and venting non-corrosive chemical fumes. Home: Ideal for dryer vents and kitchen range hoods. Agriculture: Ventilation for greenhouses, barns, and animal enclosures. Construction: Temporary ducting for dust control, ventilation, and dehumidification. Commercial Kitchens: Vents smoke, heat, and grease-laden air outside Salient Features Pure Aluminium Body Non-combustible, UV resistant, and chemical-resistant Semi-Flexible and Interlock Construction This flexible air duct is easy to transport, install and store.
