LONGWELL launches biomimetic EC fan technology

The new platform features a backward-curved impeller design that reaches 73–82% static efficiency while running 4–6 dB(A) quieter than conventional fans.

It is aimed at HVAC Original Equipment Manufacturers (OEMs), Air Handling Unit (AHU) builders, data centre cooling integrators, and service engineers.

EC fans are commonly used in ventilation systems such as HVAC systems, refrigeration units, data center cooling, and medical cleanrooms.

LONGWELL says that for years, specifying a high-efficiency EC fan for an AHU, precision-cooling unit, or data center application often meant relying on a narrow field of European suppliers. This could result in long lead times (14 to 22 weeks), along with rising procurement costs and supply chain uncertainty.

“Engineers who needed a dimensional drop-in alternative had few options that matched both performance and certification depth,” says LONGWELL.

“The LWBE3G platform was built to close that gap.”

At the core of the platform is a biomimetic, backward-curved EC impeller. The design achieves static pressure efficiency of 73 to 82%, an improvement of roughly 5–8 percentage points over conventional impeller designs, and delivers 8–12% energy savings at equivalent airflow.

The company says the aerodynamic profile also lowers noise by 4 to 6 dB(A) relative to conventional designs.

The integrated EC drive offers 0–10V, PWM, Modbus RTU and BACnet MS-TP control interfaces, twelve onboard protection functions, and an L10 bearing life of 60,000 hours at 40°C.

Bruce Li, CEO of LONGWELL, says the LWBE3G was built so that HVACR and industrial engineers can specify a high-efficiency EC fan and actually get it on time; with the certifications their compliance team needs, and with performance data they can verify.

“The biomimetic impeller is the headline,” he says.

“But the real value is giving customers a second source they can trust without re-engineering their equipment.”
