Industrial Fans & Blowers
Longwell manufactures centrifugal, axial, cross-flow, duct and exhaust fans plus blowers and motors for HVAC, refrigeration, data-center, energy-storage and OEM appliance applications — 3,000+ models in AC, DC and high-efficiency EC, ready for custom voltage, size, bracket and label.
One broad-line source for air-moving products
Ningbo Longwell Electric Technology Co., Ltd. has designed and built fans, blowers and motors since 1990. From a 40,000+ m² factory we supply components and OEM/ODM assemblies to equipment makers and ventilation projects worldwide.
Our range covers centrifugal, axial, cross-flow, duct and exhaust fans plus blowers and drive motors — in AC, DC and high-efficiency EC/BLDC versions. Under variable load, EC drives typically cut energy use by about 30% versus conventional AC motors (confirmed against your load curve). As both a component supplier and a development partner, we tailor voltage, blade, bracket, cable and label to your equipment — whether you need to drive, ventilate, cool, exhaust or air-condition. Final selection is confirmed against your duty point (airflow, static pressure, voltage and control method) and project validation.

Fans & blowers: common questions
Quick answers to help you shortlist the right family before you send specs.
What's the difference between axial, centrifugal and cross-flow fans?
Axial fans move large air volumes at low pressure and suit cooling and general ventilation. Centrifugal fans (including backward-curved and plug fans) generate higher static pressure for ducted systems and AHUs. Cross-flow (tangential) fans deliver an even, wide, low-noise air curtain ideal for appliances such as fireplaces, air curtains and split ACs.
Do you offer EC (energy-saving) versions?
Yes. Most families are available in AC, DC and high-efficiency EC/BLDC. Under variable load, EC drives typically reduce energy consumption by about 30% versus conventional AC motors and add speed control — the exact saving is confirmed against your load curve.
Can you customize voltage, size and mounting for OEM projects?
Yes — we are an OEM/ODM manufacturer. We adapt voltage, blade material, impeller diameter, bracket, connector, cable length and private labeling to your equipment, and can co-develop new configurations from drawings.
What certifications do your fans carry?
CE, UL, ETL and RoHS builds are available depending on model and market. Aerodynamic performance is tested to AMCA 210/211 methods and a third-party report can be provided on request. Quality processes are ISO 9001/14001/45001 certified.
What are your lead times for samples and production?
Samples are typically ready in 1–3 days for stock configurations, with volume production in 15–30 days depending on quantity and customization. We ship to 30+ countries.
How do I select the right fan?
Share your duty point — airflow (m³/h or CFM), static pressure, voltage/phase, control method, size envelope and quantity. Our engineers match a model and confirm the final selection against your working point and project validation. Use the form on this page or email sales@longwellfans.com.
