Wammes Tubeformer TF 1600 Ultra is a powerful, high-performance, premium spiral duct forming machine, specifically designed for the fully automatic production of large-diameter round lock-seam ducts. Compared to the TF 1401 model, the 1600 version features increased material thickness ($1.25\text{ mm}$) and a higher production speed ($80\text{ m/min}$). Like the entire Ultra series, it guarantees full compliance with European and international quality standards (DIN, SMACNA, EUROVENT).
