LONGWELL's Biomimetic EC Fan Achieves 73-82% Static Efficiency with 4-6 dB(A) Noise Reduction

Nature-inspired backward-curved EC platform delivers 8–12% energy savings and fast lead times for HVACR, data-center cooling and air-handling-unit applications

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 73–82% static efficiency 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.

Advanced Biomimetic Design

At the core of the LWBE3G platform is a biomimetic backward-curved EC impeller that improves static efficiency by 5–8 percentage points over conventional designs, delivering 8–12% energy savings at equal airflow. It operates 4–6 dB(A) quieter, reduces high-frequency noise content by more than 50%, and extends stall margin by 25–30%. Each design is validated by in-house whole-unit CFD analysis. EC drives integrate 0–10V, PWM, Modbus RTU and BACnet MS/TP control protocols with 12 protection functions and an L10 bearing life of 60,000 hours at 40°C.

The platform holds CE, UL 507, cUL and ETL certifications, along with RoHS/REACH compliance, ISO 9001/14001/45001 and EN 50155 standards. Air performance is tested to AMCA 210 / ISO 5801, with CRP registration in progress.

Proven Field Performance

In a 2024 European AHU retrofit project, the LWBE3G450-188PT-09 saved approximately 30% energy at 8,660 m³/h and over 2,000 Pa. The LWBE3G560-188PT-01 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 1–3 days for samples and 15–30 days for production, 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."
