The DVAC‑120 and DVAC‑240 Fire Duct Systems are innovative non‑coated fire‑rated ductwork solutions, engineered by industry‑leading technical experts to provide reliable fire resistance without the use of external coatings.

Both systems are specifically designed for fire‑rated ductwork applications, achieving fire performance through advanced duct construction and materials.

DVAC‑120 and DVAC‑240 are tested and certified in accordance with BS 476: Part 24: 1987 and ISO 6944‑1 (1985), providing fire resistance for stability and integrity for Type A and Type B ducts (external and internal fire exposure).

The systems have been tested by IFC for galvanized steel, stainless steel, and carbon steel ducts, including rectangular, circular, and oval configurations.
DVAC‑240 is certified for 4‑hour fire resistance, while DVAC‑120 is certified for 2‑hour fire resistance.

Both systems comply with Qatar Construction Specifications (QCS) and are approved by the Qatar Civil Defense Department (QCDD).
