SONOFLEX 25 • Acoustic laminated aluminium flexible ducts

  • Insulated
  • Aluminium laminated
  • Acoustically insulated
  • Fire resistance B - s1, d0
  • 25 mm insulation
  • Pink anti-allergical glass wool

The SONOFLEX 25 is a thermally and acoustically insulated duct, consisting of a micro-perforated inner duct of the ALUFLEX type and a laminated 3-layer outer jacket. The yellow fibreglass anti-allergic insulation has been developed especially for flexible ducting. A polyester barrier is applied between the fibreglass insulation and the inner duct to avoid the diffusion of insulation particles in the air stream.

Application

  • The SONOFLEX 25 flexible ducts are used in ventilation, air conditioning, and air handling systems where high mechanical strength, temperature, fire-resistance, and thermal and sound attenuating qualities are required

Composition

  • Micro-perforated inner duct of the ALUFLEX type, consisting of
    • 1 layer of 7 μ aluminium
    • 1 layer of 12 μ polyester (PET)
    • 1 layer of 12 μ aliminized polyester (PET)
    • Total thickness without glue: 31 μ
  • Metalized polyester outer jacket 3-layer laminate, consisting of
    • 2 layers of polyester of 12 μ each
    • 1 layer aluminium of 7µ
    • Total thickness without glue: 31 μ
  • Fibreglass insulation:
- Density: 16 kg/m³
- Thickness: 25 mm
- Thermal resistance: 0,65 K.m²/W
- Thermal conductivity: 0,039 W/m-K
- Colour: pink (Ø82 - 406 mm) / yellow (Ø457 - 508 mm)
  • Polyester barrier of 12µ between insulation and inner duct
  • Wire spacing: a steel spiral spring of different thicknesses and a pitch of 25mm (Ø82-90mm), 36mm (Ø102-508mm)
  • Colour: Aluminium

Specifications

  • Temperature range: From - 30°C till + 140°C
  • Air velocity (max): 20 m/s
  • Operating pressure: -188 up to 2500 Pa
  • Center bend radius: 1 x Diameter minimum
  • Diameter range: 82 mm - 508 mm
  • Fire resistance: class B - s1, d0 according to EN13501-1
  • As the product does not contain PVC, no toxic vapours are released should fire occur
  • Produced according EN 13180: Dia Class B, Thightness Class C, Sag<4°, Crushing strength 13-35kg compressed; 2.5kg uncompressed.

Packaging

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

Chemical resistance

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

Static properties

  • The SONOFLEX 25 is suitable for applications where static discharges have to be avoided

Restrictions

  • The SONOFLEX 25 ducts are not suitable for transporting air with a high concentration of acid and base
  • The SONOFLEX 25 can not be used for discharging combustion gases from open fire places and oil-fired boilers

Accessories

  • Clamps type MCA
  • Aluminium tape, type ALUTAPE 40S PREMIUM
