The Delta Duct FD5 is a premium flexible duct designed for maximum durability and thermal efficiency. It features an inner core composed of a double layer of ALU PET and clear polyester, providing superior resistance to mechanical abuse and thermal conduction. The core is reinforced with a coated steel spring helix and surrounded by a high-quality fiberglass insulation layer and a metalized PET outer jacket.

Real-World Applications

• High-Demand Commercial HVAC: Perfect for malls and hotels where high air volumes and thermal stability are required.

• Tropical Climates: Extensively used in regions with high humidity to prevent condensation on the duct surface.

• Complex Routing: Allows ducting around structural obstacles where fabricated metal ducts would be too costly to install.
