For 35 years, Longwell has engineered EC, AC, and DC fan and motor systems for the operations that cannot fail — from data centers and premium HVAC, to rail transit, cold chain logistics, and industrial production. Trusted by Fortune 500 OEMs across 30+ countries.
Longwell was founded in 1990 in Yuyao, Ningbo — the heart of China’s advanced manufacturing belt. What began as a precision fan component workshop has grown into a vertically integrated ventilation technology group, with 4,000㎡+ of manufacturing floor, dedicated aerodynamics and CFD simulation labs, and a global export network spanning Europe, Americas, and Asia-Pacific.
Longwell’s core strength is the seamless vertical integration of high-performance aerodynamics with our independently developed drive motor technology — covering AC induction motors, brushless DC, and intelligent EC (Electronically Commutated) motors with integrated control electronics.
A single engineering team designs the impeller, the motor, and the control algorithm together — achieving efficiency and acoustic performance that component-assembled competitors cannot match. Our EC motors reach up to 90% efficiency with on-board 0–10V / PWM / Modbus RTU control.
Our brand positioning is built on three interlocking strengths that define how we engineer, deliver, and support every fan system we build.
We integrate high-performance aerodynamics with independently developed AC, DC, and EC motor drive technology. From impeller geometry to control electronics — engineered as one system.
Longwell offers full-process OEM/ODM: 3D STEP model integration, sample delivery in 1–3 days, bulk order in 15–30 days, 12-month warranty, and 24/7 technical support.
Data center precision cooling, oven fans at 300°C+, fire suppression axial systems, BESS thermal management, high-static-pressure AHU plug fans. Built for the critical.
Longwell’s product library spans EC, DC, and AC platforms — centrifugal, axial, and cross-flow fan technologies — with the industry’s broadest customization capability.
Forward-curved, backward-inclined, and backward-curved geometries. AHU, FCU, heat pump, BESS, commercial HVAC. EC efficiency up to 90%.
Data center in-row cooling, refrigeration condensers, heat exchangers, industrial ventilation. LWAE3G: IP55, ±1° pitch, PWM/0–10V/Modbus.
Ultra-slim profile for fan coil units, HRV/ERV, elevator ventilation, and display cabinet cooling. Silent, compact, width-customizable.
Brushless EC motors (60W–2,200W+) and industrial AC induction motors. Integrated or standalone. Servo motor series for precision drive.
High-temperature oven fans (350°C), corrosion-resistant exhaust, fire suppression jet fans, explosion-proof fans for hazardous environments.
Poultry/livestock ventilation, greenhouse climate, commercial kitchen exhaust, air curtain systems. IP-rated for harsh environments.
Our engineering team applies CFD simulation at every stage of impeller and housing design — predicting airflow behavior, minimizing turbulence losses, and optimizing blade geometry before a single prototype is cut.
Fans with best-in-class SFP ratings, compliant with EU ErP 2021/2015 and exceeding ASHRAE 90.1 benchmarks. EC motor platform delivers 30–50% energy savings vs legacy AC+VFD configurations.
Every Longwell product is designed, tested, and certified to meet the requirements of the world’s most demanding markets.
Performance tested to AMCA 210/211 method. Third-party test reports available on request.
Longwell’s solutions are deployed across six continents in industries where performance and reliability are non-negotiable.
