The SEMIFLEX is a semi-flexible 1-layer aluminium alloy duct. The SEMIFLEX duct is easy to install on circular connection parts. As the product does not contain PVC, no toxic vapours are released should fire occur

• The SEMIFLEX flexible ducts are used in ventilation, air conditioning, and air handling systems where a high mechanical strength is required

• Spiral wound and profiled strip from aluminium alloy, thickness: 80 μ
• Colour: Aluminium

• Temperature range: From - 30 °C till + 250 °C (max 400°C for a short time)
• Air velocity (max): 25 m / sec (4912ft / min)
• Operating pressure (max): + 2000 Pa (200 mm WC)
• Bend radius: 1 X D
• Specific weight: 0.17 kg/m ( Ø100 mm)
• Diameter range: 82 mm - 315 mm
• Fire resistance: ZP3/1992 (fire resistance of chimneys of small diameters)

• Each standard length of 3 m is compressed in an individual, reinforced cardboard box

• Good resistance to many solvents
• Moderate resistance to acid and base

• The SEMIFLEX is suitable for applications where static discharges have to be avoided

• The SEMIFLEX ducts are not suitable for transporting air with a high concentration of acid and base
• The SEMIFLEX cannot be used for discharging combustion gases from open fireplaces and oil-fired boilers

• Clamps type MCA
• Aluminium tape , type Alutape

• The connection between the ventilation system and the plenum boxes shall be done with the use of flexible ducts made of pure aluminium
• ATC
• Type SEMIFLEX

• Semiflex, 254
