In modern buildings, fire safety is not only a regulatory requirement but also a moral obligation to protect human life. One of the most effective solutions in this area is the butterfly type fire damper. Integrated into ventilation systems, these dampers prevent the spread of smoke and flames between different sections of a building, significantly minimizing damage and risk.
What Is a Butterfly Type Fire Damper?
A butterfly type fire damper is a safety device designed to automatically close ventilation ducts in the event of a fire, thereby preventing the fire from spreading to other areas. These products are equipped with a thermal fuse that activates at 72°C. Once the ambient air temperature exceeds this threshold, the fuse breaks and triggers a spring mechanism that closes the damper blade, isolating the affected section.
Certified According to EN 1366-2 and DIN 4102 Standards
Butterfly type fire dampers manufactured by Doğuş Teknik are certified to withstand 300 Pa vacuum pressure for 240 minutes, in accordance with the EN 1366-2 standard. This certification ensures reliable performance even under extreme conditions.
The damper blade is surrounded with an intumescent strip that expands in high heat, fully sealing the perimeter of the damper to prevent smoke and flame leakage. This sealing material complies with DIN 4102 fire resistance standards, as does the fire-rated mastic used to fill all joint areas of the damper. This construction significantly enhances the safety and integrity of the product.
Where and How Are They Used?
Butterfly type fire dampers are widely used in:
Hospitals
Shopping malls
Hotels
Industrial facilities

They are typically installed at wall penetrations within the ductwork and can be mounted either in front of or outside the wall, depending on the structural requirements.
