Multi-leaf dampers are indispensable components in ventilation technology and enable flexible and efficient control of the air flow.

Due to their wide range of applications and robust properties, they are used in numerous areas.

In ventilation technology, this applies to residential buildings, office buildings, production halls and other buildings to regulate the room air.

Another important area of ​​application is air handling units. Here, the dampers are used to control the air distribution and to adjust the room temperature.

They are also used in industrial plants, especially in processes where precise control of the air flow is required.

The volume flow controller type VRSE is a cost-effective alternative to the volume flow controller of type VRME.

It is used for pressure-independent control of variable volume flows in supply air and exhaust air systems and it consists of a control damper, which at the same time can also serve as a shut-off damper, and two measuring sticks that are integrated in the casing as well as the electronic
control components.

The multi-use shut-off damper AK no.219 is a further development of the proven shut-off damper no. 220 from Aerotechnik E. Siegwart.

The multi-use shut-off damper is factory-provided with a lever for manual adjustment as well as a bracket for electronic actuators (Belimo LM / CM). The integrated mounting clip of the bracket can
be extended if required.

The VRC-238 is a field adjustable high capacity constant airflow regulator.

This round damper is designed to provide automatic, precise, balanced pressure-independent maximum constant airflow in round duct systems without use of electricity, sensors or controls.

VRC-238 is the next-generation of the VRK-233 constant airflow regulator.

This enhanced version showcases an advanced, durable, easy to adjust lock-in nub for airflow control, meticulously designed for optimal performance and efficiency.
