Heavy Duty Lay Flat Ducting Tubing, 25in x 328ft Large Industrial Ventilation Hose for Air Blowers, Exhaust Fans, Grow Rooms, Warehouse & Agricultural Airflow (328 ft X 25 Inch)

Heavy Duty Lay Flat Ducting Tubing, 25in x 328ft Large Industrial Ventilation Hose for Air Blowers, Exhaust Fans, Grow Rooms, Warehouse & Agricultural Airflow (328 ft X 25 Inch)

• Extra Long 328ft Length – Covers long distance airflow needs from end to end. Ideal for ventilating large warehouses, connecting remote grow rooms, or exhausting fumes from construction sites without joining multiple shorter tubes. Saves time and reduces leak points.
• 25 Inch Width – Standard Fit for Most Fans – Flat width of 25 inches (approx. 16 inches diameter when inflated) works with many axial fans, centrifugal blowers, and inline duct fans. Compatible with standard 16″ round outlets using duct tape or clamps (adapters may be needed for smaller outlets).
• Heavy Duty & Flexible Polyethylene Construction – Made from tear-resistant, weather-resistant lay flat material. Remains flexible in cold or hot conditions, yet strong enough for continuous blower operation. Can be used for fresh air supply, dust extraction, or odor control.
• Lay Flat Design for Compact Storage – Collapses completely when not in use, taking up minimal shelf space. Unrolls quickly in seconds and re-rolls easily after job completion. Lightweight enough for one person to handle a 328ft roll.
• Cost-Effective & Disposable Option – Affordable per square foot compared to rigid metal ductwork. Can be reused multiple times or disposed of after heavy contamination, making it a practical choice for spray painting booths, asbestos abatement, or emergency smoke ventilation.
