DFSCF-4

MAXI Flexible Connectors

DFSCF-4

Type A: Silicone Coated Glassfabric based materials – performance summary:

  • Type: DFSCF-4 Silicone Coated G/F (Double Sided).
  • Operating Temperature Range: -50°C to +250°C.
  • Operating Pressure Range: 508mm WG (20” WG) (Max).
  • Typical Applications: Heating & Ventilation, Smoke Extract duties.

 

Single Layer Flexible Connections – All Types:

  • Single Layer, or “ply” Flexible connections are designed to provide: Vibration isolation, absorb expansion, compensate for misalignment in ductwork and reduce noise breakout when using flexible materials having dedicated noise attenuation properties.
  • Available in the following standard geometries:
  • “Circular Flat Flanged” (C.F.F.) - Circular with “plain ends” suitable for “Jubilee Clip” type installation.
  • “Rectangular Flat Flanged” (R.F.F.) - Square / rectangular with “plain ends” suitable for backing flat installation.
  • “Circular Angle Flanged” (C.A.F.) - Circular with flanged ends at 90 degrees to the body suitable for steel backing flanges.
  • “Rectangular Angle Flanged” (R.A.F.) - Square or rectangular with flanged ends at 90 degrees to the body suitable for steel backing flanges.
  • Can also be manufactured as tapering and / or transitioning from circular to rectangular geometries.
  • Can be supplied pre-punched to match clients existing ductwork flanges or “plain flanges” for drilling during installation, where specific hole centres are unknown.
  • Fire rated materials available for specific applications.
  • All related steelwork can be specified, designed and manufactured in-house, including:
  • Steel Backing Flats / Flanges, Steel Inner sleeves to protect the Flexible Connection from abrasive particles or high velocity gasses / buffeting.

 

Other Types of Flexible Connections available, (the majority of which are coated in-house):

Type B: Neoprene Coated Glassfabric.

Type C: Specialist materials having Acoustic properties, chemical resistance or insensitive to buffeting.
