## Description

From the manufacturer Product Description This ducting is designed for various ventilation, circulation, and heating/cooling transfer applications. It features four-layer protection, making it more durable and resistant to leaks than single-layer designs. The internal layer is made of heavy-duty dual aluminum foil that is fire/flame resistant. Its outer layer utilizes dual PVC thermoplastic that protects the aluminum from cuts and tears while stopping leakage. Each duct tube is held together by an internal steel-wire spiral that is flexible and easy to install in hard to reach places. The ducting can be shortened by cutting the tube to fit various applications. Includes two stainless steel duct clamps. Applications Primarily used with duct fan systems in various air circulation and ventilation projects including hydroponic grow rooms and tents, bathrooms and attics, heating and cooling transportation, and other installations. It is also used to cool AV equipment rooms, closets, racks, and cabinets. Aluminum Ducting Flexible ducting tube designed to route airflow in home HVAC applications. Creates a passage to supply, return, and exhaust air. The Most Essential Ventilation Accessory Ducting tubes are a vital part of any room that requires a regular exchange of air, facilitating air delivery for proper ventilation. Using ducting will streamline the airflow, ensuring good indoor air quality and thermal comfort in your home or workplace. Multi-layer Construction Features dual layer protection made of an outer thermoplastic and an inner aluminum. Employs a four-layer design that resists leaks, tears, and cuts. Wire Coil Structure The spiral wire holds the tubular shape, while the inner lining stays smooth and straight when stretched out, maximizing airflow and diminishing CFM loss. Flexible Ducting Makes installation easy by bending the aluminum duct tube in any direction. This allows you to accommodate most space restrictions. Steel Duct Clamps This set includes two steel duct clamps that secure the aluminum tubing to your inline fan or other duct openings. Fastens the loop using a Phillips screw.

## Questions & Answers

**Q: What is the fully compressed length of the 8FT 4" diameter duct?**
A: 5 1/2 inches

**Q: Is this safe to vent a portable ac? ac's can get really hot.**
A: I've never owned a portable AC. If there is a 4"  circle shaped vent hole on the portable AC, it should tolerate the heat. Stationary ACs condensate water, there is no vent hole.

**Q: anyone use this for garage auto exhaust tube?**
A: I am currently using this to exhaust the air in my wood shop

**Q: Is this suitable for marine use?**
A: No paperwork came with it indicating whether it is USCG compliant (if there is such a requirement).  If you want to use it as a duct for a bilge blower, I would say go ahead and use it.  If you are concerned about fire retardancy, I suggest you contact the seller first.
