Fanryntech is pleased to introduce its Semi-Rigid Aluminum Duct, a reliable solution for low- and medium-pressure air conditioning, ventilation, and industrial applications.

The duct is made of soft aluminum foil with a unique interlocked and knotted continuous seam. It is lightweight and flexible, yet strong enough to maintain its shape without additional support in most installations.

Key highlights include:

• Diameter range: 50mm to 500mm (2″ to 20″)

• Extension ratio: 1:3

• Temperature range: -25°C to +300°C

• Working pressure: up to 2500 Pa

• Fire resistance: non-combustible, no toxic gas release at high temperature

The semi-rigid aluminum duct is available in standard lengths of 1.5m, 3.0m, and 6.0m. It is suitable for boiler systems, chimney liners, bathroom or kitchen venting, and many other ventilation needs.

Fanryntech also supports custom packaging with your own logo. Free samples are available upon request (postage fee applies).
