Stainless Steel Fire Damper for HVAC Safety

Key Benefits for Contractors

• Corrosion-Resistant Structure: Housing, blades, and mechanism available in SS304/SS316, ideal for humid or coastal environments with reduced lifecycle cost.

• Reliable Safety Closure: Fusible links (commonly 68°C/72°C/74°C) and spring-return mechanism ensure quick shut-off during fire or power failure.

• Air-Tight & Low Pressure Drop: Blade-seal design minimizes leakage and reduces operating pressure loss, supporting system efficiency.

• Easy Installation & Maintenance: Standard flange connection (TDC/TDF or angle flange) and service opening design for routine inspection and testing.

• Wide Customization: Available in rectangular/round, single or multi-blade, manual or motorized, and non-standard sizes to fit project drawings.

• Code Compliance: Models can be supplied in accordance with UL 555 (North America) or EN 1366-2 / EN 13501-3 (Europe), subject to available certifications.

Typical Applications

• Commercial complexes, offices, hospitals, and labs requiring fire separation in ventilation systems

• Coastal and humid environments, food & pharma factories, commercial kitchen exhaust ducts

• Public and industrial buildings requiring enhanced corrosion resistance and fire safety

Technical Specifications

Installation & Maintenance

• Install at fire-rated partitions or duct sections as per local code; use certified firestop sealants for gaps.

• Ensure airflow direction matches arrow on the housing; avoid twisting or stress on duct and damper body.

• Motorized types must be wired by a qualified electrician and tested for open/close cycles.

• Conduct regular cleaning and functional testing, checking blade movement and seal integrity during annual fire drills.

Ordering Information

Recommended to specify: duct shape and dimensions, installation position, fire rating requirement, airflow/pressure data, control type (fusible/motorized), flange standard, and applicable codes (UL/EN/local).

Compliance & Documentation

Models can be supplied with relevant fire test reports and compliance documents depending on project location.
