What is fire flaps?

Fire flaps are safety devices used in HVAC systems to prevent the spread of smoke and flames during a fire. They are typically installed in ductwork and automatically close when a fire is detected, helping to contain the fire within a specific area and protect other parts of the building. This mechanism is crucial for maintaining safe egress routes and minimizing property damage during a fire incident. Fire flaps are often part of a broader fire protection strategy in commercial and industrial buildings.
