ThermoFlo™ 2000V Series flexible air ducting is an ultra-durable solution suitable for general applications that do not require UL approvals. Crafted with a single-layer metallized foil, a black vinyl coating, and a metal coil, this ducting system is perfect for low-pressure environments and straightforward in-line ducting applications. It features a double-layered aluminum/PVC casing exterior with UV inhibitors for longevity even in direct sunlight. The metal helix maintains the duct's shape, allowing for easy attachment to connectors and fans. Its 25-foot standard length won’t unravel when cut, allowing for easy custom fittings and reducing installation time and costs. Maintenance-free when installed as per the manufacturer's guidelines, it is a cost-effective solution for fresh air intake/exhaust applications like construction sites or temporary work areas.
