Why customers choose TaskHolt Tools

Meet the VIVOSUN 4 inch flexible aluminum duct. This 25 ft long hose is designed to move air with efficiency in a variety of setups, from HVAC runs to dryer exhausts and grow tent ventilation. The length is adjustable, letting you run the duct tight along walls, above ceilings, or around corners without sacrificing airflow.

  • Durable aluminum construction resists heat and corrosion for lasting use.
  • Triple-layer protection with flame-retardant inner and outer foil plus a PET middle layer reduces leaks and wear.
  • Built in steel wire lets you bend and lengthen to fit exhaust blowers or inline fans.
  • Includes two clamps for quick, secure connections and a tight seal.

The duct is lightweight and portable, making it easier to handle during installation in a range of spaces. Its flexible design helps you shape routes that minimize resistance and optimize airflow.

Versatile across commercial and residential environments, this duct serves HVAC runs, bathroom vents, stove and dryer exhausts, kitchen vents, grow rooms, and greenhouse air circulation. It also helps cool AV rooms, closets, and cabinets by providing reliable, adjustable airflow.

Practical tips for optimal installation

  • Match duct size to fan diameter for a leak-proof fit, such as pairing a 4 inch fan with 4 inch ducting.
  • Keep runs as straight as possible and secure connections with the included clamps to minimize resistance.
