Lightweight air ventilation tubing (similar to a plastic bag) manufactured from durable clear polyethylene, has been engineered for maximum elasticity, flexibility, toughness, and resistance to splitting and tearing. Most commonly used for transferring large volumes of forced air to confined areas, such as water restoration projects, building renovations or other temporary applications. Not designed for permanent installations. Collapses when airflow stops. Unaffected by moisture and most chemicals. Resistant to bacterial and fungal growth (suitable for use in food preparation areas). 41° F to 150° F (5° C to 65° C) temperature range. 22″ diameter (not inflated). Length: 500′.
