Flexible Duct

The NUOENWEI Single-Layer High-Temperature Resistant Fabric-Reinforced Ducting is engineered for reliable hot air conveyance and fume extraction in demanding thermal environments. Built with a single-ply reinforced fabric wall and a helical steel wire structure, it operates continuously from -45°C to +300°C and is available in inner diameters from 100mm to 1000mm with fully customizable lengths. Whether you are routing exhaust from a portable heater on a construction site, extracting fumes from a foundry furnace, or supplying hot air to a drying system, this duct is built to deliver consistent airflow across extreme temperature conditions.

NUOENWEI single-layer negative-pressure air duct with tightening buckles is a purpose-built flexible suction hose engineered for high-efficiency exhaust ventilation in demanding industrial environments. Unlike general-purpose air hoses, this duct is specifically constructed for negative-pressure operation—meaning it maintains structural integrity under vacuum conditions where suction forces would collapse inferior hoses. The integrated tightening buckle system at each end creates a secure, tool-free connection to fans, scrubbers, and ducting networks, minimizing air leakage and simplifying installation. Whether you are exhausting fumes from an underground heading, removing dust from a tunneling face, or managing airborne contaminants in a processing facility, this duct is built to perform.

The NUOENWEI Dog Agility Training Tunnel is a lightweight, heavy-duty training tunnel engineered for dogs at every skill level—from first-time learners to competition-grade agility athletes. Made from premium PVC material with a film-coated surface, this tunnel delivers the perfect balance of portability and structural durability. Whether you are a professional trainer setting up a full course or a pet owner looking for a fun bonding activity, this PVC dog training tunnel is built to perform.
