NUOENWEI Telescopic Loading Bellows are engineered for dust-free, efficient loading of dry bulk solids into tankers, trucks, railcars, and stockpiles. Available in standard and high-temperature configurations, these telescopic loading spouts extend and retract to match vessel heights while containing airborne dust at the source. Ideal for cement, fly ash, grain, fertilizer, clinker, and other powdered or granular materials.

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.

NUOENWEI PCA Hose with Integrated Wiring delivers preconditioned air + built-in electrical cables for aircraft ground AC. 8"-14" IDs, -25°C to 80°C, YKK zippers included.

NUOENWEI Large-diameter insulated air duct features a triple-layer PVC construction with 3mm thermal insulation core, available in 4″–59″ (100mm–1500mm) diameters. Ideal for grain chillers, outdoor tent AC, and portable HVAC systems. Custom lengths & colors available. ISO9001 certified.

NUOENWEI Oxford cloth high temperature air duct delivers -45°C to 300°C performance. Flexible heat resistant hose with spiral steel wire for industrial ventilation & exhaust.
