Headquarters Laboratory
Motivation for building a ventilation and noise laboratory
1. Verify the airflow distribution of the vents and provide correct performance data
2. Test the level of valve leakage to improve product competitiveness with world-class manufacturers
3. Overcome the difficulties in obtaining UL certification and increase the speed of fire damper performance verification
4. Provide noise product performance to improve the noise quality environment
5. Improve the product quality and corporate image of the group company
