Противопожарный воздуховод ZhaoYi фенольный стандарт
The fire-resistant ventilation duct from ZhaoYi is a high-performance solution designed for smoke extraction and ventilation systems. Constructed from a phenolic composite material reinforced with steel, this duct provides reliable protection by preventing the spread of fire and smoke within a building.
This product is ideal for central air conditioning systems and specialized fire-fighting exhaust networks. With high-density materials and superior sealing, the duct ensures airtight airflow, which is critical for the efficiency of safety systems in public and industrial facilities.
Special emphasis is placed on thermal resistance, as the material can withstand extreme temperatures up to 300°C while maintaining structural integrity. This makes it an essential component for modern ventilation designs that comply with strict fire safety standards.
