• Bend radius: 0.54 X D
• Diameter range: 82 mm - 508 mm
• Fire safety: LNE classification obtained M1
• Report number: C050541 - Cemate / 15
• As the product does not contain PVC, no toxic vapours are released should fire occur

• Each standard length of 10 m is compressed in an individual, reinforced cardboard box

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

• The ALUFLEX AA3 is suitable for applications where static discharges have to be avoided

• The ALUFLEX AA3 ducts are not suitable for transporting air with a high concentration of acid and base
• The ALUFLEX AA3 cannot be used for discharging combustion gases from open fireplaces and oil-fired boilers

Explanation :

Aluflex AA3 = Type of Flexible duct

254 = Diameter of flexible duct

• Aluminium flexible type Aluflex 112

• The connection between the ventilation system and the plenum boxes shall be done with the use of aluminium flexible ducts, approved according to EN 13180. The Aluminium flexible duct consists of 3 Aluminium-layers os 7 micron, combined with 2 Polyester-layers of 12 micron. The diameter shall be adapted to the air flow.
