DAYTON 2TGA8 Fire Damper, 11-3/4 Inch Width, Rectangular

Dayton 2TGA8 square fire damper is used in ventilation and HVAC systems to enhance fire safety in buildings. These dampers are strategically placed within ductwork to prevent the spread of fire and smoke throughout different areas. When exposed to high temperatures, they automatically close, blocking the passage of flames and harmful gases.

Working Mechanism:

• During a fire, the surrounding temperature rises significantly.
• Equipped with a heat-sensitive fusible link, the fire damper responds to elevated temperatures.
• Once the temperature hits 165 degrees F, the fusible link melts, activating closure.
• The damper employs gravity for automatic closure and the melted link triggers it due to the damper's weight.
• Once shut, the damper's blade blocks duct airflow, curbing fire, heat and smoke spread.

Features:

• Dayton 2TGA8 square fire damper features robust, 22-gauge galvanized steel construction to ensure fire resistance and durability.
• It is activated by a fusible link triggered at elevated temperatures, the damper swiftly closes using spring-loaded gates, effectively containing fire and smoke propagation.
• This 2TGA8 fire damper features an automated gravity-based closure mechanism to halt the airflow when exposed to high temperatures, bolstering fire safety measures.
• It includes a frame-less flange that optimises airflow control within the ducts, enhancing overall ventilation efficiency.

Compatible Accessories:

• Dayton Fusible Links: These links serve as a crucial component, triggering closure at elevated temperatures to enhance the damper's fire containment capabilities.
• Dayton Vertical / Horizontal Retaining Angles: They offer compatibility for both vertical and horizontal orientations. It aids in secure installation, ensuring the optimal functioning of the fire damper in various mounting positions.

Frequently Asked Questions:

Q. Can the fusible link be replaced after it triggers closure?

A. Yes, the fusible link can be replaced after use, restoring the damper's functionality.

Q. What is the maximum temperature that the fusible link can withstand?

A. The fusible link can withstand a maximum temperature of 165 degrees F. As the link exceeds this temperature value, it triggers the closure of the damper to prevent potential fire hazards.

Q. What is the construction material of the curtain-style blade in this damper?

A. The curtain-style blade has galvanized steel construction, providing fire resistance and durability.

Q. How does the damper prevent the spread of fire and smoke?

A. The damper's closure mechanism blocks airflow, preventing the passage of fire and smoke through ducts.
