NUOENWEI Flexible Ventilation Pipe – Heavy-Duty PVC Industrial Ducting for Air, Fume & Dust Extraction
NUOENWEI has developed a truly versatile flexible ventilation pipe that solves traditional ducting problems: stiffness, air leaks, corrosion, and difficult installation. Made from high-grade PVC with a seamless, the pipe features no longitudinal seams – meaning zero air leakage along the wall, lower pressure drop, and longer service life.
The pipe body thickness ranges from 0.4mm to 0.65mm, offering a balance between flexibility and durability. The standard bright orange-yellow color ensures high visibility on job sites, while other colors (grey, white, blue, red, black, green) are available for custom branding or application matching.
Each meter of the pipe comes with a 304 stainless steel hanging loop for simple suspension from hooks or beams. The flared bell-mouth end with a PP rope allows quick coupling to fans or joining multiple sections for unlimited length extension. Optional belt buckles or zippers provide extra connection security.
NUOENWEI Flexible Ventilation Pipe
The NUOENWEI flexible ventilation pipe is a premium PVC industrial duct engineered for superior airflow, chemical resistance, and mechanical strength. Whether you need to extract welding fumes, ventilate a confined space, or move dust in a woodworking shop, this lightweight yet rugged hose delivers exceptional performance from -15℃ to 80℃.

Product Advantages
Chemical & Abrasion Resistance
The PVC compound resists acids, alkalis, oils, and many corrosive agents. It also withstands abrasive dust and granular materials without tearing – ideal for mining, chemical plants, and cement works.
Flame Retardant & Self-Extinguishing
Meets industrial fire safety standards. The material slows flame spread, giving workers critical extra seconds in emergency situations.
100% Waterproof & Air-Tight
Seamless circumferential construction means no longitudinal leaks. Whether moving high‑humidity air or liquid mist, the pipe keeps your system efficient.
Telescopic & Omnidirectional Bending
While maintaining structural integrity, the NUOENWEI flexible ventilation pipe can be compressed to half its length or extended fully. It bends in any direction without kinking – perfect for tight corners and moving equipment.
Lightweight & Portable
Weighs significantly less than rubber or metal ducts. One person can carry, deploy, and retrieve a 10-meter section, reducing labor costs and fatigue.
Non-Toxic & Odor-Free
No harmful plasticizers, no fiberglass dust, no flaking particles. Safe for food‑adjacent areas, hospitals, and indoor air quality‑sensitive sites.
Wide Temperature Tolerance
Operates reliably from -15℃ (cold storage warehouses) to 80℃ (near ovens or engine exhausts).
Easy Installation & Extension
The built-in 304 stainless steel hanging loops allow instant suspension. The flared bell‑mouth with PP rope creates a tight, tool‑free seal when connecting to fan outlets or another pipe section.
Customizable Options
Diameter up to 1500 mm
Any length (up to 20 m+ continuous)
Belt buckles or zippers for pressurized systems
Match color to your safety or brand code
