Description

Pressed & Segmented Duct Bends (BP & BS) – Complete Ventilation Bending Solutions

The BP Pressed Bends and BS Segmented Bends provide a comprehensive range of high-quality duct fittings designed to create smooth and efficient changes of direction in circular ventilation systems. Suitable for both spiral and plain ductwork, these bends deliver optimal airflow performance, high airtightness, and reliable installation across a wide range of HVAC applications.


BP Pressed Bends – Compact & Efficient Airflow Control

BP Pressed Bends are manufactured in a single pressed form, creating a smooth contour that minimises airflow resistance and pressure loss.

Key Benefits

  • Low Pressure Loss
    Smooth pressed design ensures efficient airflow with reduced resistance. 

  • Improved Airtightness
    Seam-welded construction enhances system sealing, with some versions achieving airtightness class D

  • Compact Design
    Ideal for tighter spaces where shorter-radius bends are required.

  • Safe & Easy Handling
    Hemmed edges reduce risk of injury during installation. 

  • Quick Installation
    Simple push-fit connection into spiral or plain duct systems. 

Typical Use

  • General HVAC installations
  • Systems requiring compact duct routing
  • Applications prioritising ease of installation and cost efficiency

BS Segmented Bends – High-Efficiency, Large-Diameter Performance

BS Segmented Bends are constructed from multiple sections, creating a larger bend radius that significantly reduces airflow resistance—ideal for larger ducts and high-performance systems.

Key Benefits

  • Reduced Pressure Loss
    Multi-segment construction allows larger radii (1.5D or 2D options) for improved airflow efficiency. 

  • Designed for Larger Diameters
    Available in sizes up to 1600 mm, making them ideal for industrial and large-scale HVAC systems. 

  • High Airtightness Options
    Versions with EPDM gaskets provide airtightness class D in accordance with EN 12237. 

  • Robust Construction
    Manufactured from multiple joined segments for strength and durability. 

  • Wide Material Selection
    Available in galvanised steel, stainless steel, aluminium, and copper to suit various environments. 

Typical Use

  • Large commercial HVAC systems
  • Industrial ventilation
  • Applications where airflow efficiency is critical
  • Swimming pools or corrosive environments (stainless steel options)

Shared Features (BP & BS Bends)

  • Suitable for spiral and plain round duct systems
  • Wide range of angles (15° to 90°)
  • Available with male, female, or double female connections
  • Designed for easy insertion and secure installation
  • Optimised radius (~1 x duct diameter) for balanced airflow performance
