Heat Resistant Portable Air Duct – Flexible Vent Hose for HVAC & Industrial Applications

Heavy-Duty Flexible Ventilation Ducting (Industrial Grade)

Ditch the flimsy, collapsing vent hoses that tear under the slightest pressure. These heavy-duty industrial air ducts are engineered with a reinforced flame-retardant PVC skin and a rigid internal wire frame to handle the punishing airflow requirements of welding fume extraction, job site blowers, and confined space ventilation. The flexible, accordion-style design allows you to snake the duct around tight corners in shop environments without pinching or cutting off critical airflow. We stock these commercial-grade ventilation ducts at wholesale prices to ensure you get real value for the dollar on your shop and site-safety equipment.

Key Features:

• Flame-Retardant PVC: Constructed from thick, high-heat resistant PVC that prevents melting or structural failure when venting hot welding fumes or heavy exhaust.
• Reinforced Wire Core: Features a heavy-gauge internal wire helix that keeps the duct fully expanded even under high-pressure suction, preventing accidental collapse.
• Industrial Connectivity: Equipped with integrated drawstring cuffs, allowing you to create an airtight seal on standard industrial blowers, fans, and wall vents in seconds.
• Collapsible Portability: Fully folds down into a fraction of its length, making it easy to throw in the back of a service truck or store in a tight warehouse corner between jobs.
• Multiple Lengths & Diameters: Available in high-volume 30.5 cm (12") and 50.8 cm (20") diameters to match the output capacity of your heavy-duty shop exhaust fans.
