Highlights at a glance

EC axial fans are powered by electronically commutated motors, which combine the stability of AC power with the efficiency of DC motors. These fans are engineered to generate stable and high-velocity airflow, making them suitable for HVAC, industrial cooling, and large ventilation systems. Compared to traditional fans, EC axial fans offer higher energy efficiency, more precise control, and significantly lower noise levels.

1. High-Efficiency EC Motor Design: Precise Control and Energy Savings. At the heart of Longwell’s EC axial fans is its electronically commutated motor (EC motor), engineered to achieve outstanding efficiency and precise control, making it an ideal alternative to German imported fans.

FAQs
What control and feedback options do LONGWELL EC axial fans support?
All our EC axial fans support both 0-10 VDC and PWM control inputs for smooth speed adjustment. They also provide a tachometer output (open collector) for real-time speed monitoring. This allows seamless integration into HVAC systems, AHUs, heat pumps, and industrial equipment.

Are LONGWELL EC axial fans suitable for harsh environments?
Yes. Our LWAE-250 Series offers IP55 protection (dust-tight and protected against low-pressure water jets). The PA66 impeller resists corrosion and moisture. Operating temperature ranges from -25°C to +60°C, making them ideal for cold storage, outdoor condensers, agricultural ventilation, and industrial workshops.

What certifications do LONGWELL EC axial fans have for global markets?
Our EC axial fans carry CE, RoHS, ETL, ISO9001, ISO14001, BSCI, and VLD certifications. Some models are also AMCA certified. These marks simplify your customs clearance and help you qualify for infrastructure or OEM projects in Europe, North America, and Asia.

How much energy can I save by switching from AC axial fans to LONGWELL EC axial fans?
LONGWELL EC axial fans use a brushless DC (BLEC) motor with up to 55% lower power consumption than traditional AC fans at the same airflow. For example, our LWAE-250 Series saves 30-55% energy depending on operating point. This directly reduces your customers’ electricity bills and helps meet green building standards.

Can LONGWELL customize EC axial fans for my specific OEM requirements?
Absolutely. As a direct manufacturer with over 20 years of export experience, we offer full OEM/ODM services. You can customize cable length, connector type, terminal coating, frame color, and even private labeling. We also provide free pre-production samples with test reports for qualified B2B buyers.

What is your quality assurance and after-sales support?
Each fan undergoes 100% balancing and performance testing before shipment. We provide a 12-month warranty and 48-hour video technical support. Our factory is audited by Fortune 500 HVAC brands, and our customer retention rate exceeds 92%. We are the actual manufacturer, not a trading company-you can request a live video tour of our Smart Factory anytime.
