Damper

HVAC dampers are essential components used to regulate, isolate, and control airflow within ventilation and air conditioning systems. By managing the volume and direction of air, dampers improve system efficiency, maintain indoor comfort, and enhance fire safety. Depending on the application, they are available in manual or motorized configurations for residential, commercial, and industrial buildings.

In-Line Dampers

In-line dampers are used to regulate or shut off airflow in duct systems. They are available in manual and motorized versions, including rectangular opposed blade, parallel blade, and round flanged or flangeless models. These dampers provide precise airflow control with reliable performance.

Fire & Smoke Dampers

Fire and smoke dampers are designed to prevent the spread of fire and smoke through HVAC ductwork. They are activated either by a fusible link or a motorized actuator connected to the building's fire alarm system. Available in rectangular and round configurations, these dampers are essential components of modern smoke management systems.

Backdraft Dampers

Backdraft dampers prevent reverse airflow when ventilation equipment is not operating. Acting as a non-return air valve, they improve system efficiency and protect ductwork from unwanted air movement. They are available in both rectangular and round designs.

Car Park Ventilation Dampers

Car park ventilation dampers control supply and exhaust airflow in enclosed parking garages while supporting smoke extraction during emergencies. Designed with reinforced blades and compatible with 2–15 Nm actuators, they offer excellent durability, fire resistance, and easy installation.
