COMBIFLEX N BLACK • Combined laminated flexible ducts

The COMBIFLEX N BLACK is a fully flexible 4-layer aluminium / polyester laminate duct. The outside is a co-polymer, antistatic layer (standard length 10 m). The aluminium and polyester layers overlap each other entirely. This “sandwich” construction of the layers results in a higher external resistance against sparks.

• The COMBIFLEX N BLACK flexible ducts are used in ventilation, air conditioning, and air handling systems with low and moderate air pressure where a high mechanical strength, temperature and fire resistance is required

• 4-layer: Aluminium 1x layer 7 micron, 1 layer polyester (PET) of 12 micron, 1 layer 12 micron metalized polyester (MPET), 1 layer PVC of 65 micron, wire helix 25 mm (Ø82 mm), 36 mm (Ø102 mm and larger)
• Colour: black

• Temperature range: From - 30°C till + 140°C
• Air velocity (max): 20 m/s
• Operating pressure (max): -188 to +2500Pa
• Bend radius: 1x Dia minimum
• Pressure loss: see diagram
• Diameter range: 82 mm - 508 mm
• EU - EN 13180 Dia. Class B, Tightness Class C, Sag < 10º, Crushing Strength 13-35 kg compressed, 2-5 kg uncompressed

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

• Good resistance to many solvents

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

• Clamps, type MCA
• Textile tape, type GREYTAPE

• The extraction of the welding stations shall be done with the use of a polyester flexible duct with aluminium inner core
• ATC type COMBIFLEX N BLACK

• COMBIFLEX N BLACK, 254
