Wanhe Testing’s Range Hood Air Volume and Energy Efficiency Testing Equipment Gains Wide Market Recognition

The independently developed Range Hood Air Volume and Energy Efficiency Testing Equipment (model WH‑YJ01‑100B) from Zhongshan Wanhe Testing Equipment Development Co., Ltd. has recently received multiple bulk orders from leading household appliance manufacturers. The system is designed in accordance with the international standard IEC61591 and incorporates a dedicated test apparatus for “external‑discharge range hood air performance” as specified in Appendix C of the Chinese standard GB/T 17713‑2011 Range Hoods.

Key technical specifications include an air volume measurement range of 3–1200 m³/h with an accuracy of ±1.5%, static/differential pressure measurement from 0–1000Pa with ±0.25% accuracy, and power measurement up to 1100W with ±1.0% accuracy. The equipment can accurately map static pressure vs. air volume curves, air volume vs. rotational speed, air volume vs. current, and power vs. efficiency curves, and supports testing under both suction and exhaust modes. Test items cover air volume, static pressure, efficiency, total pressure efficiency, static pressure at specified airflow, peak static pressure, peak airflow, total pressure efficiency at specified airflow, and main motor input power at specified airflow, with automatic calculation of both old and new national standard values. The series also includes the WH‑YJ01‑100A Range Hood Whole‑Machine Life Test Stand, controlled by PLC and touchscreen, equipped with a dedicated robotic arm for position adjustment and pneumatic cylinders that simulate human finger touches on switches. With continuous innovation in range hood testing, Wanhe Testing has earned positive market feedback and strengthened its reputation as a specialized non‑standard testing equipment manufacturer.
