Smart control

Controllers can be configured for different applications and automatically adjust airflow based on temperature, CO2 concentration, room pressure, and airflow offset for precise environmental control.

Energy-Saving Operation

The valve body, blades, and airflow measurement unit use a low-resistance airflow-friendly design with high airtightness, reducing resistance by more than 30% compared with similar products.

Compact design

Thanks to the low-resistance component design, the valve body is only 300 mm long, saving site space and simplifying installation.

Multiple Applications

Widely used in clean systems such as biopharmaceutical and hospitals, laboratory negative-pressure systems, and comfort systems such as offices and hotels.

Remote Monitoring

Supports integration with building automation systems for remote monitoring and management, improving operation and maintenance efficiency.
