AVK – AIR DAMPERS FOR RECTANGULAR DUCTS
The AVK air dampers are designed for automatic or manual control of airflow in rectangular duct systems. Built with a galvanized steel case and rotary blade, they ensure reliable shut-off or volume regulation in HVAC systems.
The AVK series air dampers are high-quality components used to control airflow volume or completely shut off air in rectangular duct systems. Suitable for various commercial, industrial, or residential settings, these dampers are compatible with duct sizes ranging from 400×200 mm to 600×350 mm.
Constructed with a durable galvanized steel casing and rotary blade, the AVK dampers ensure long-lasting performance even under continuous operation. Their automatic actuation makes them ideal for integration into smart or sensor-based ventilation systems, offering precise air regulation. In situations where manual adjustment is preferred or required, the AVK allows for an easy switch to manual control mode, providing flexibility for maintenance or non-automated environments.
These dampers are essential for optimizing energy efficiency, balancing airflow, and maintaining air quality in modern ducted HVAC systems.
