NUOENWEI Flexible Ventilation Ducting – Heavy-Duty PVC Industrial Duct Hose for Air, Fume & Dust Extraction
NUOENWEI flexible ventilation ducting
The NUOENWEI flexible ventilation ducting is a professional-grade industrial ventilation solution designed to solve traditional ducting problems: stiffness, air leaks, corrosion, and difficult installation. Made from high-quality PVC material with a seamless circumferential construction, this flexible ducting offers zero longitudinal air leakage, lower pressure drop, and extended service life.
Whether you need to extract welding fumes, ventilate a confined space, move dust in a woodworking shop, or set up temporary ventilation on a construction site, this lightweight yet rugged hose delivers exceptional performance in demanding environments. The duct body thickness ranges from 0.4mm to 0.65mm, offering an optimal balance between flexibility and durability.
The standard bright orange-yellow color ensures high visibility on job sites, while alternative colors (grey, white, blue, red, black, green) are available for custom branding or application matching. Each meter of the duct comes with a 304 stainless steel hanging loop for simple suspension from hooks or beams. The flared bell-mouth end with PP rope allows quick coupling to fans or joining multiple sections for unlimited length extension. Optional belt buckles or zippers provide extra connection security
