HVAC duct forming machinery is essential for the production of air ducts used in ventilation and air conditioning systems. These machines are designed to shape, connect, and prepare sheet metal components with high precision, ensuring strong, airtight, and standardized ductwork.

StanGroup Liberty Seamless Machinery manufactures and supplies equipment for both rectangular (square) and round HVAC duct production, providing reliable solutions for different fabrication needs.

Pittsburgh S-cleat C-drive machine plus Flanger attachment

This multifunctional machine is used to create various connection profiles for rectangular HVAC ducts. It combines Pittsburgh lock forming, S-cleat and C-drive profiles, as well as flange forming in one unit, allowing efficient preparation of duct edges for assembly.

• Forms Pittsburgh lock seams for longitudinal connections
• Produces S-cleat and C-drive profiles for duct assembly
• Includes flanger attachment for edge forming
• Ensures strong and airtight duct connections
• Reduces need for multiple separate machines

TDFC / TDCF Lock & Cleats Roll-Former

This machine is designed to form TDF and TDC flanges directly on duct edges. It also produces cleats and supports both flat and reinforced grooved flange profiles.

• Forms TDF and TDC flanges
• Produces cleats for fastening
• Supports flat and grooved flange options
• High production speed up to 45 ft/min
• Compatible with standard HVAC connection systems

Industrial HVAC Spiral Tube Duct Forming Machine (TF1602)

The TF1602 spiral tube former is designed for the production of round HVAC ducts with high precision and consistent quality. It forms spiral ducts from metal strips using a continuous forming process.
