Highlights at a glance

BLEC Motor Saves 30-55% Energy vs AC Fans. The 250mm EC axial fan uses a brushless DC EC motor. It cuts power use by up to 55% compared to AC fans. For 500 units running 24/7, annual savings exceed 30,000 kWh, directly lowering OPEX.

0-10V / PWM Control + Tachometer Output. Each LONGWELL 250mm EC axial fan supports 0-10 VDC and PWM input, plus a tach output for real-time speed monitoring. It integrates easily into AHUs, heat pumps, condensers, server racks, and industrial enclosures. Airflow adjusts automatically up to 1916 m³/h.

IP55 & -25°C to +60°C for Harsh Environments. The LWAE-250 Series features IP55 protection (dust and water jets), PA66 blades, and an operating range of -25°C to +60°C. Ideal for cold storage, outdoor condensers, agricultural ventilation, livestock houses, and workshops.

Built-in Protections Maximize Uptime. Onboard EC controller includes locked-rotor protection, reverse polarity protection, over-voltage protection, and soft start. This prevents damage from unstable power or mechanical jams. The fan delivers 50,000 hours L10 life.

Multiple Models for Exact Performance Needs. Choose from four versions: LWAE3G250SS-7PNW-07 / 7PKW-08: 2480 RPM, 85W, 1627 m³/h LWAE3G250SS-7PNW-09 / 7PKW-10: 2950 RPM, 115W, 1916 m³/h All run on 220V 50/60Hz, static pressure up to 180 Pa, noise only 60 dB(A).

Full Certifications for Smooth Customs. The 250mm EC axial fan carries CE, RoHS, ETL, ISO, and VLD marks. This simplifies import compliance and helps you win tenders. We provide batch traceability, test reports, and a 12-month warranty.

Plug-and-Play Replacement for 250mm AC Fans. Standard 250mm frame and mounting holes allow direct retrofit. Upgrade equipment without modifying panels or ductwork-perfect for aftermarket distributors.

We serve OEM, ODM, and wholesale partners in HVAC/R, industrial cooling, agricultural ventilation, data centers, telecom cabinets, commercial kitchen exhaust, and parking garage ventilation.

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.
