The COMBIFLEX 2100 is a fully flexible 6-layer aluminium / polyester laminate duct. The outside is a co-polymer, antistatic layer. 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 2100 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

• Inner duct of the ALUFLEX AA3 type and a co-polymer outer jacket, total thickness: 145 μ Wire spacing: a steel spiral spring of different thicknesses and a pitch of 25 mm (Ø82-90 mm), 36 mm (Ø102-508 mm)
• Colour : Grey

• Temperature range: From - 30°C till + 140°C
• Air velocity (max): 30 m / sec (5900 ft / min)
• Operating pressure (max): + 2500 Pa (250 mm WC)
• Bend radius: 0.54 x D + 25 mm
• Pressure loss: see diagram
• Diameter range: 82 mm - 508 mm
• Fire resistance: LNE classification obtained M1
• Report number: F080235 - Cemate/3

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

• Good resistance to many solvents

• The COMBIFLEX 2100 ducts are not suitable for transporting air with a high concentration of acid and base
• The COMBIFLEX 2100 cannot be used for discharging combustion gases from open fireplaces and oil-fired boilers

• Clamps type MCA
• Aluminium tape type Alutape

• The extraction of the welding stations shall be done with the use of a polyester flexible duct with aluminium inner core
• ATC
• Type COMBIFLEX 2100

• Combiflex 2100, 254
