Fire Dampers

Fire Damper

Fire Dampers are critical safety components in HVAC systems, designed to prevent the spread of flames, heat, and smoke through ductwork during a fire emergency. Installed in air ducts that pass through fire-rated walls, floors, and partitions, they automatically close when exposed to high temperatures, creating a protective barrier.

By isolating affected areas, Fire Dampers help maintain safe evacuation routes, minimize property damage, and provide vital time for firefighting and rescue operations. Manufactured with precision and reliability by Shandong Wanneng Group, these dampers combine robust construction with proven safety performance.

Product Description

Our Fire Dampers are engineered to provide dependable fire protection in ventilation systems by automatically closing when fire or heat is detected. Using fusible links or electronic actuators, the blades shut tightly to stop flames and smoke from spreading into unaffected areas. Constructed with heat-resistant steel frames and durable blades, these dampers withstand high operating temperatures while maintaining airtight closure.

Available in static, dynamic, smoke, and combination models, Fire Dampers can be tailored to suit different applications, from commercial buildings to industrial facilities and high-rise complexes. Their versatile design ensures compatibility with modern HVAC systems while complying with international fire safety codes. When properly installed and maintained, Fire Dampers serve as a first line of defense against fire spread, protecting both occupants and property.

FAQs

Q1: What is a fire damper and how does it work?

A fire damper is a safety device in HVAC ducts that automatically closes during high heat or fire. It prevents flames and smoke from traveling through the ventilation system.

Q2: Where is a fire damper required in a building?

A fire damper is required wherever ducts penetrate fire-rated walls, floors, or partitions to maintain the integrity of fire barriers.

Q3: How often should a fire damper be maintained?

Fire dampers should be inspected and tested regularly to ensure proper closure. Cleaning and checking fusible links or actuators are essential for reliable performance.

Q4: What types of fire dampers are available?

There are static fire dampers, dynamic fire dampers, smoke dampers, and combination dampers designed for different airflow and safety needs.

Q5: What happens if a fire damper fails during an emergency?

If a fire damper fails, fire and smoke can quickly spread through ducts, compromising evacuation routes and increasing property damage. Proper installation and maintenance prevent such failures.
