DAMPERS & AIR CONTROL SYSTEMS
Dampers are used throughout HVAC systems to control airflow and, in critical cases, to protect a building from the spread of fire and smoke. While they’re often hidden inside ductwork, they play a major role in how a system performs and how a building responds during an emergency.
Saturn provides a complete range of damper solutions for commercial, industrial, and government projects. We help ensure the right damper is selected for the application, coordinated with the design, and installed in a way that meets both code and performance expectations.
LIFE SAFETY DAMPERS (Fire & Smoke Dampers)
Fire and smoke dampers are installed where ductwork passes through rated walls, floors, or partitions. Their purpose is to maintain the integrity of those barriers and help control the spread of fire and smoke during an emergency.
Depending on the application, a project may require a fire damper, a smoke damper, or a combination of both.
Fire Dampers
Fire dampers are designed to close when heat reaches a specific temperature, typically through a fusible link. Once released, the damper blades close and help prevent fire from spreading through the duct system.
- Available in static and dynamic designs
- Curtain-style and multi-blade configurations
- Installed in rated walls and floor penetrations
- Operate without motors or controls
Smoke Dampers
Smoke dampers are used to control the movement of smoke within a building. Unlike fire dampers, they are motorized and connected to the fire alarm or building control system.
- Leakage-rated to limit smoke transfer
- Motorized (open/close or modulating)
- Used as part of engineered smoke control systems
- Installed in ductwork and air transfer openings
Combination Fire / Smoke Dampers
Combination dampers handle both functions in a single assembly. They respond to heat like a fire damper and also operate with an actuator like a smoke damper.
- Provide both fire protection and smoke control
- Motorized operation with multi-blade construction
- Used where both ratings are required by code
- Common in shafts, corridors, and rated partitions
CEILING RADIATION DAMPERS
Ceiling radiation dampers are installed at ceiling openings. Typically where diffusers or grilles are located to maintain the fire-resistance rating of the ceiling assembly.
- Designed for use in floor/ceiling and roof/ceiling systems
- Installed above diffusers and grilles
- Available for round and rectangular ducts
- May include integral airflow control options
CONTROL DAMPERS
Control Dampers (Volume Control)
Control dampers are used to regulate airflow within the system. They are essential for balancing air, controlling zones, and maintaining proper system operation.
- Opposed blade and parallel blade designs
- Manual balancing or motorized control
- Used in supply, return, and exhaust systems
- Designed for efficient airflow and low pressure drop
Backdraft Dampers
Backdraft dampers prevent air from flowing in the wrong direction. They are commonly used in exhaust and intake systems to stop reverse airflow when fans are off.
- Gravity-operated or motorized designs
- Open with airflow, close when airflow stops
- Low resistance to forward airflow
- Used in exhaust, relief, and intake applications
INDUSTRIAL DAMPERS & HEAVY-DUTY APPLICATIONS
Some applications go beyond standard HVAC conditions and require dampers built for higher temperatures, pressures, or more demanding environments. These are typically found in industrial and process systems.
Industrial Control Dampers
Used to regulate airflow in high-velocity or high-pressure systems.
- Heavy-duty construction
- Designed for demanding operating conditions
- Used in industrial ventilation and process air systems
Isolation Dampers
Isolation dampers are designed to provide tight shut-off when a section of a system needs to be isolated.
- Low-leakage or bubble-tight options
- Used in high-pressure or critical systems
- Common in power, process, and industrial applications
Vane Inlet Dampers
Installed at the inlet of fans to control airflow and improve system efficiency.
- Provide smooth airflow control into the fan
- Improve fan performance and energy efficiency
- Used in larger air handling systems
Heavy-Duty Backdraft Dampers
Built for larger systems where higher airflow and pressure conditions exist.
- Designed for industrial applications
- Prevent reverse airflow in large systems
- Durable construction for long-term use
HOW DAMPERS FIT INTO THE SYSTEM
Each type of damper serves a specific purpose:
- Fire and smoke dampers protect life safety and meet code
- Control dampers manage airflow and system performance
- Relief and backdraft dampers maintain airflow direction and pressure
- Industrial dampers handle demanding operating conditions
Selecting the right damper depends on the application, code requirements, and how the system is expected to operate.
