Product Overview

The non-insulated flexible aluminum air duct is engineered for efficient air transfer, exhaust ventilation, and climate control across HVAC, industrial, and hydroponic applications. Built with multi-layer aluminum foil encapsulated around a heavy-duty spiral steel wire, this ducting maintains structural integrity while allowing flexible routing in tight spaces. Its lightproof and flame-retardant properties make it an ideal choice for connecting inline fans, grow room exhaust systems, and general ducting networks.

Key Performance Characteristics

  • Fire-Resistant & Durable: Multi-ply aluminum foil construction resists high temperatures and resists flame propagation.
  • Flexible Bending & Structural Stability: Internal spiral steel wire wire helix allows smooth, tight bends without kinking or collapsing airflow.
  • Lightproof Air Dispersion: Zero light transmission through duct wall, safeguarding sensitive indoor growing photoperiods.
  • Universal Compatibility: Standardized ducting diameters fit all standard inline exhaust fans, carbon filters, duct fan flanges, and vents.
