HVAC Components

HVAC components have been a main field of activity for Gebhardt-Stahl for decades. A particular focus has always been paid to ductwork components, especially those for rectangular air ducts. For this reason, you will find almost everything necessary in our range for building ductwork, ductwork assembly or servicing and cleaning purposes.

Every day, many customers around the world are satisfied by our innovative and high-quality products in the fields of technical building equipment, plant engineering, ventilation planning, ductwork construction and duct fitting.

The core of our range are the various 4-bolt connection systems. These consist of slip on flanges and matching corners. Our range extends from simple flanges for ductwork without higher demands for leak tightness to our protected Premium flanges, which are suitable for sealing class D without any additional sealing measures on the flange (TÜV certified).

In addition, we offer you a wide range of accessories such as access doors/panels, flexible connectors, duct connection materials as well as mounting/hanging components. Everything available from stock.






For all queries please don´t hesitate to contact us. We look forward to hearing from you.
