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)
