Oval ducts

bringing you the best of both spiral and rectangular ducts - easy on the eyes look and adjustable height for unobtrusive installation...
  • Oval ducts

    Oval air ducts have very similar characteristics and advantages as spiral round air ducts. They are made from stretched spiral pipes. The features of the flat oval duct make it a very good option for designers when space constraints do not allow the use of round and rectangular ducts. The rounded corners do not create the turbulence inherent in a rectangular duct. This allows for higher volume airflow and higher speed without generating noise and dynamic losses.

    Oval ducts
  • Duct connections

    Connecting parts are used to connect two oval air ducts.

    They are not used to connect air ducts to another fitting.

    The connecting parts are internal and external and the choice of which one to use depends on you ...

    Available with or without rubber seal.

  • Elbows

    Elbows for oval ducts. Bending range between 30 and 90 degrees.

    There are two types of oval elbows - OVAL BFL and OVAL BFL1. That needs to be taken into consideration when placing orders.

    They are available with and without rubber seal.

    Elbows
  • T-branches and Y-branches

    T-shaped and Y-shaped branches with deviation degrees between 45 and 90.

    Like the elbows, the tees are also divided into several types depending on the direction of deviation and this must be taken into account when ordering them.

    Like all other fittings, these are available with or without a rubber seal

    T-branches and Y-branches
  • Reducers

    Used to connect different sizes of oval ducts or to connect oval ducts with rectangular or spiral ducts.

    Reducers
  • Spigots

    Spigots are a budget solution for branching from a main air duct.

    They somewhat replace the use of a T-piece or X-piece, but it is not recommended to use them frequently.

    They are more suitable for accidental branches, which were necessary to be introduces after the completion of a ventilation system.

    They are produced with a branch angle of 45 and 90 degrees.

    Like all other fittings, they are available with and without a rubber seal

    Spigots
  • End caps

    End caps for sealing off an oval air duct.

    They are produced in two variants - for internal and external application.

    They are available with and without a rubber seal

    End caps
