Ducting Bends for ventilation are produced in diameters range 80 mm to 1600 mm of galvanized, aluminum and stainless steel sheet at 15, 30, 45, 60 and 90 degree angles.

It is recommended to choose the version with EPDM seals to ensure achieving "D" class leakage (airtightness) according to EN 12237 (SITAC certificate).

In both versions there are 4 types of ducting bends:

  • BP (w/o seals) and BPL (with seals) pressed bends - in diameters range 80 to 250 mm.
  • BS (w/o seals) and BSL (with seals) segmented bends of R=D radius - manufactured in diameters range 200 to 1600 mm.
  • BSK (w/o seals) and BSKL (with seals) short segmented bends of R=0,6D radius
  • BSD (w/o seals) and BSDL (with seals) long bends of R=2D radius - which are manufactured in diameters range 160 to 1250 mm.

Optionally segmented ducting bends can be produced with various non-standard diameters, a thickness of sheet, radii, and angles.
