NINGBO, China, July 3, 2026 /PRNewswire/ -- Ningbo Longwell Electric Technology Co., Ltd. (LONGWELL), a leading EC fan manufacturer and air-moving solutions provider, today unveiled its biomimetic EC fan platform. The nature-inspired impeller design achieves while operating significantly quieter than conventional fans, serving HVAC OEMs, AHU builders, data-center cooling integrators and engineers seeking a reliable alternative to premium European EC fans without redesigning equipment.
At the core of the is a biomimetic backward-curved EC impeller that improves static efficiency by over conventional designs, delivering at equal airflow. It operates , reduces high-frequency noise content by more than , and extends stall margin by . Each design is validated by in-house whole-unit CFD analysis. EC drives integrate control protocols with 12 protection functions and an L10 bearing life of .
The platform holds certifications, along with RoHS/REACH compliance, ISO 9001/14001/45001 and EN 50155 standards. Air performance is tested to , with CRP registration in progress.
In a 2024 European AHU retrofit project, the saved approximately at 8,660 m³/h and over 2,000 Pa. The delivered 16,039 m³/h – matching the 16,000-class ebm-papst R3G560 for direct 1:1 replacement without air chamber modifications. Lead times run and , compared to 14–22 weeks typical of imported premium EC fans.
"We are competing on impeller physics, not just price," said Bruce Li, Chief Executive Officer of LONGWELL. "When the aerodynamics are this efficient and this quiet, switching becomes an easy engineering decision."
Founded in 1990 and based in Yuyao, Ningbo, LONGWELL designs and manufactures EC and AC fans and motors, exporting to more than 30 countries. Learn more at .
