Manufacturing of air ducts
For the professional manufacturing of air ducts and ventilation systems, we offer a wide range of products and components essential for creating efficient and reliable ventilation solutions. This category includes all the elements required for the construction, connection, and optimisation of air ducts.
Efficiency begins at the core
Rectangular air duct systems are indispensable in numerous applications – from office buildings and industrial facilities to complex air conditioning systems.
They place special demands on stability, airtightness, energy efficiency, and ease of installation. A crucial role is played by the profile, which forms the frame for each individual duct element and significantly contributes to the overall performance of the air duct system.
In our Air Duct Solutions business unit, we combine decades of experience in the production of air duct profiles. With high vertical integration, state-of-the-art production technology, and a deep understanding of practical requirements, we develop robust, precise, and durability-oriented profiles that serve as the structural backbone of air ducts.
These profiles not only ensure a dimensionally stable connection between duct elements, but also actively help to increase the system’s airtightness – a key factor for energy efficiency. After all, every profile that is not perfectly fitted or lacks stability poses a risk of leakage, which can significantly increase the energy consumption of ventilation systems.
In short: Our air duct profiles are far more than just connecting elements – they are a central building block for reliable, energy-efficient, and long-lasting air duct systems.
Slip-on flanges for air ducts
Our air duct profiles are available in various lengths, material grades, and system variants, offering maximum flexibility for a wide range of applications in air and climate technology. Depending on the requirements, versions with or without injected sealing compound are available – ideally matched to the desired level of airtightness and the hygienic demands of the specific application area.
High-quality workmanship and thoughtful design ensure a reliable, airtight connection of rectangular air duct segments, contributing to efficient air distribution. Whether in industry, healthcare, or sensitive environments – our profiles meet even the highest standards for airtightness, stability, and hygiene.
Corners
Our corners enable a simple, fast, and precise connection of rectangular air ducts. Thanks to their well-designed geometry and high manufacturing quality, they ensure reliable installation with exact alignment. The corners are available in various designs and material grades, and are perfectly matched to our air duct profile systems. They offer maximum compatibility and stability – ideal for efficient and secure air duct connections across a wide range of applications.
For stable and efficient air duct systems
Air duct reinforcements and baffle fastenings play a central role in the construction of high-quality air duct systems.
They ensure that air ducts remain dimensionally stable even under higher pressure conditions, preventing deformation or unwanted vibrations. Reinforcing the duct walls helps avoid material distortion and ensures the long-term reliable operation of the entire air distribution system.
Baffle fastenings also enable targeted control of airflow – especially in areas with directional changes or large duct cross-sections. They minimize flow losses, reduce noise, and noticeably improve the energy efficiency of the system.
Our components for air duct reinforcement and baffle mounting are available in various designs and material qualities, and can be flexibly integrated into a wide range of system concepts. This provides the foundation for durable, hygienic, and high-performance air duct systems – fully aligned with optimal operating conditions and high technical standards.
Efficient flow control
Our fasteners are specifically designed for securing baffles in ventilation systems. Their high-quality workmanship and precise fit guarantee a secure and long-lasting connection. Made from galvanized steel or stainless steel, our fasteners are corrosion-resistant and suitable for use in harsh environments.
Safe air ducts in accordance with standards
DIN EN 1507 sets clear requirements for the reinforcement of ventilation ducts – and for good reason:
Vibrations in large-format ducts can not only cause disturbing noise but also promote structural damage.
Our reinforcement systems offer an effective solution.
They minimize vibrations, improve sound insulation, and simultaneously increase the stability of your air ducts.
The result: consistently quiet and safe operation of your ventilation system – even under demanding operating conditions.
Rely on certified quality and reliable technology – with our reinforcement systems, you lay the foundation for durable and standards-compliant air duct systems.
