SIE’s Seat Performance Test Bench is designed to evaluate air volume and fan performance in ventilated car seats. Equipped with an ASHRAE 51 flow nozzle, the system precisely measures air intake and outlet flow, as well as ventilation resistance (pressure drop). It also enables analysis of blower characteristics, including P-Q curves and maximum airflow.

As electric vehicles continue to gain dominance in the automotive industry, ventilated seat systems are drawing increasing attention for both comfort and energy efficiency. This test bench provides a reliable and efficient solution for evaluating these advanced features.

With a range of 3-400 CMH and optional blower power supply, the system is fully automated using a LabVIEW-based UI and compact DAQ system—maximizing test reliability and efficiency.
