DVAC Welded Circular Ducts are manufactured from cold‑rolled steel coils (minimum 16 gauge) in compliance with NFPA 96 standards.

These ducts are primarily designed for kitchen ventilation and exhaust systems, connected to exhaust fans to remove heat, smoke, and odors from kitchens and cooking areas. Stainless steel ducts are also available for the same application.

Commercial kitchens often operate at temperatures exceeding 100°C, combined with high humidity levels. Properly constructed welded duct systems ensure safe and efficient air extraction, contributing to a healthier and more comfortable environment.

Construction of DVAC Welded Circular Ducts complies with:

• • – SMACNA
  • – NFPA 96

All DVAC welders are fully qualified and hold WPQ (Welder Performance Qualification) certifications issued by third‑party inspectors in accordance with approved WPS (Welding Procedure Specifications).
