DUCT CONNECTION

Strong. Safe. Reliable.

To ensure that your air ducts remain tight even with longer edge lengths and strong pressures, we recommend the use of our sliding strips or threaded clamps. In order to meet your individual requirements, you will find sliding strips and duct clamps of the most varied designs in our portfolio, as well as liner and cold shrink tapes in different sizes.

The selection of a suitable tape and its correct use are also of great importance when it comes to the tightness of a connection in air duct construction.

Compatibility

All components are tried and tested and can be combined with our air duct profile systems.

Tightness

Recommended especially for large edge lengths and high pressures.

Assembly

All air duct connection components are quick and easy to assemble.

CLEATS

Cleats are a popular product for the connection of air ducts, since they are easy to use, stable and offering a nice finish to the flange connection. Gebhardt-Stahl cleats fit all our flange series – Premium-, P-, S- or L-series and all 3 types – 20 flange, 30 flange and 40 flange.Wherever space is very limited during duct fitting, cleats are first choice for duct connection as less space is needed for assembly compared to G-clamps.Cleats should be cut in lengths of 70-100mm and used in distances of not more than 300mm - ideally at a distance of not more than 200mm

  • Sturdy design
  • Suitable for all Gebhardt air duct flange systems
  • Suitable for all flange sizes 20 mm, 30 mm and 40 mm

CLAMPS "STANDARD"

In many cases, G-clamps are the optimum solution for connecting rectangular ventilation ducts. They are easy to work with and ensure a secure, strong connection. Two G-clamps should always be placed close to the corners. The distance between two G-clamps should not exceed 250mm along the flange.Suitable for all Gebhardt flange series and flange types.All Gebhardt G-clamps delivered with fitted screw M8 x 20mm.

  • With double bead for increased stability
  • Galvanised steel
  • Material thickness 2.5 or 3.0 mm

OUR EXPERTS FOR HVAC COMPONENTS

Our focus on continuous development has allowed us to grow over the past decades from a supplier of HVAC components to a leading company in the field of air duct flanges and a full-range supplier in the field of HVAC accessories.

In the course of this development, however, one thing has always been in the foreground - the pursuit of professional, high-quality and individual solutions for you, our customers and partners.

CLAMPS "PLUS"

Duct clamps are in many cases the optimal solution for connecting rectangular ventilation ducts. The Gebhardt threaded clamps are easy to process and ensure a secure, strong connection. Especially for ventilation systems with high pressures, the duct clamps ensure a tight connection. Two duct clamps should always be in close proximity to the corner angle. The distance between the other clips should not exceed 250 mm.

All Gebhardt duct clips fit all air duct profile systems and are suitable for all profile sizes. Delivery always with mounted M8 screw.

  • V-bead for increased stability
  • End tips for better grip
  • 90° angle for increased contact pressure
  • Galvanised steel, stainless steel 1.4301 or 1.4404
