Indusvent products

Tapers are spot welded and made of 0.90 mm galvanised sheet metal. When assembling with wide pull rings [f.bb], rapid lock pull rings [f.lyn] and loose flanges [f.b.m.fl] length (L) is increased by 2 x 50 mm. State D- and d dimensions when ordering. Length L is stated in the table below. The difference between the larger and smaller diameter (D - d) is plotted on the vertical axis of the coordinate system. By following the line from this point to the intersection, the length (L) can be read at the corresponding point on the horizontal axis.

Access doors are made of 1.25 mm galvanised sheet metal, such that the inside is smooth and has a close fit.

Sliding dampers are made of 1.25 and 1.50 mm galvanised sheet metal with a damper of 2.00 mm galvanised sheet metal.

Telescopic ducts are made from 0.75 mm and 0.90 mm galvanised sheet metal and supplied with rapid lock pull rings, incl. rubber seal.

Flanges are made in accordance with JKF’s standard, and are a standard component in the product range. Flanges are stock items in hot dip galvanised finish, but can be supplied either untreated or painted. Flanges in other dimensions or profiles are available to order.

Supplied with the same JKF assembly methods as duct systems. Jet caps from diameter ø700 - ø1000 mm are fitted with flanges as standard. Jet caps are fitted with an internal cone and drain hose for disposal of water. See next page for pressure loss curves.

Laser welded and longitudinally lock formed ducts are galvanised and made from 0.75 mm, 0.90 mm or 1.00 mm sheet metal (s). Ducts are also available in 1.25 mm sheet metal. Also available in other qualities and dimensions to order. Ducts of up to ø400 mm diameter are supplied as standard laser welded in lengths of 0.5 m, 1.0 m and 2.0 m. Other sizes from ø450 mm diameter are supplied as longitudinally lock formed ducts in standard lengths of 0.5 m, 1.0 m and 2.0 m.
