Fire dampers are essential safety components in ventilation systems. These fire dampers prevent the spread of fire, smoke, and hot gases through air ducts in the event of a fire. The fire dampers automatically close when the temperature in the ventilation duct exceeds a certain threshold, playing a crucial role in protecting buildings and the people within them.
How do fire dampers work?
Fire dampers operate using a thermal or electric actuator that closes the damper when the temperature in the air duct reaches a preset value. The closure of the fire damper ensures that fire and smoke do not spread through the air ducts to other parts of the building. This delays the spread of fire and protects escape routes and other critical areas.
What is the difference between fire dampers and Butterfly dampers?
Fire dampers and Butterfly dampers both aim to regulate airflow and protect against the spread of fire and smoke, but there are several differences. Fire dampers are specifically designed to close at high temperatures and primarily serve as fire safety measures in ventilation systems. Butterfly dampers are mainly used for regulating and shutting off airflows in ventilation systems. They can be used, for example, in smoke and fire-resistant systems.
The different variants of fire dampers in our range
- Fire Dampers (80mm to 800mm): these are available in round and rectangular designs.
- Butterfly dampers (diameters of: 80mm to 200mm): the round Butterfly dampers can be installed in a round ventilation duct.
- Smoke and Fire-Resistant Butterfly dampers (100mm to 200mm): these round valves provide dual protection against both smoke and heat.
- Rectangular Butterfly dampers (ranging from 100x200mm to 1500x800mm): this valve is suitable for larger ventilation systems.
Additionally, we offer specific versions:
- Manual Fire Damper: this fire damper is easy to operate manually, intended for residential and commercial buildings.
- Fire Damper with Servo Motor: this fire damper has automatic operation via a motor.
- Fire Damper with Smoke Sensor: this fire damper features smoke detection and closure upon smoke development.
- Fire Damper with End Switch: this fire damper closes the air duct in case of fire and provides an electrical feedback once the damper is fully closed. This end switch sends a signal to a building management system (BMS) or fire alarm center to indicate that the damper is correctly closed.
For which ventilation ducts are the fire dampers suitable?
The round fire dampers are suitable for round ventilation pipes and can be easily used in both heat recovery (HR) systems and mechanical ventilation (MV) systems. The rectangular fire dampers fit perfectly into recessed ducts and flat ventilation pipes. These dampers ensure that in the event of a fire, the airflow is effectively shut off, preventing the spread of fire and smoke through the ventilation system. It is important that the fire damper fits exactly in the duct, without any margin, to ensure effective sealing in the event of a fire.
How to install a fire damper?
The installation of a fire damper is crucial for the safety and effectiveness of the ventilation system. Ensure that the fire damper fits precisely in the ventilation duct, with no space for air leakage. The fire damper must be securely mounted according to the manufacturer's instructions. After installation, test the operation of the fire damper to ensure it closes and opens correctly.
How to maintain a fire damper?
Regular maintenance of the fire damper is essential to ensure its operation in emergency situations. Have the fire dampers checked and cleaned at least once a year to ensure they are in good condition. Additionally, ensure that the dampers are free from dust and dirt.
What are the benefits of fire dampers?
- Protection against smoke and fire: the fire dampers automatically close to prevent the spread of smoke and fire through ventilation systems.
- Extended lifespan: the fire dampers help protect the air ducts from damage caused by fire and smoke, extending the lifespan of these systems.
- Safety: by using fire dampers, the safety of occupants and employees in buildings is significantly increased.
