• Aluminium foil flexible ducting: The outer layer employs thickened black PVC material, effectively blocking light leakage. Beneath the black PVC layer, the ducting comprises a double-layer aluminium foil composite with an internal steel wire spiral structure. This ensures the ducting maintains its shape, preventing tears or pinholes within the ventilation system
• Flame Retardant & Temperature Resistant: Our ducting is fully flame retardant, meeting stringent safety standards. It withstands a broad temperature range from -30°C to 100°C, making it suitable for diverse operating environments. The ducting performs reliably in both frigid climates and high-temperature conditions
• Easy Installation: The exhaust hose is highly flexible and simple to install, sliding directly into your duct fan, exhaust pipe, carbon filter, or light reflector
• Product Dimensions: Fully extended, the exhaust hose measures 1 metre, 2 metres, 3 metres, 4 metres, 5 metres, with internal diameters of 150mm, 160mm, 170mm, 180mm, 200mm, 250mm, 300mm, 350mm, 400mm, 450mm, and 500mm. Please verify the correct size before purchasing
• Versatile Applications: This ducting is suitable for HVAC systems, facilitating air conveyance and circulation in scenarios including: kitchen exhaust ventilation (cooking fumes), greenhouses and grow rooms (air recirculation, intake, exhaust, and luminaire heat dissipation), bathroom odour and moisture extraction, drying rooms, and grow tents
