Highlights at a glance

As a professional ventilation fan manufacturer, LONGWELL presents the LWAE-450 Series 450mm EC axial fan for industrial HVAC, OEM, and wholesale buyers who demand high airflow, energy efficiency, and smart controllability.

1.High Airflow up to 6695 m³/h for Large Scale Ventilation. The 450mm EC axial fan delivers up to 6695 cubic meters per hour at 1590 RPM with only 420W power consumption (model LWAE3G450SS-5MNW-01). This makes it ideal for air handling units, condensers, industrial workshops, agricultural ventilation, and data center cooling. The high static pressure curve (see performance chart) ensures stable operation even with duct resistance.

2. BLEC Motor Saves 30-55% Energy vs. AC Fans.All LWAE-450 fans use a brushless DC EC motor. Compared to traditional AC axial fans of the same size, energy savings range from 30% to 55%. For a facility running 100 units 24/7, annual electricity cost reduction can exceed 15,000 USD. Lower OPEX is a direct benefit to your customers.

3. 0-10V / PWM Speed Control with Tachometer Output.Each 450mm EC axial fan supports both 0-10 VDC and PWM control inputs for precise speed adjustment. A tachometer output provides real-time RPM monitoring. This allows seamless integration into building automation systems, heat pumps, refrigeration units, and server room cooling systems.

4. Multiple Models for Suction or Blowing Direction.The LWAE-450 Series offers both suction type (SS suffix) and blowing type (ST suffix). You can choose the optimal airflow direction for your equipment layout. Models include: LWAE3G450SS-5MNW-01 (suction) and LWAE3G450ST-5MNW-02 (blowing) at 1590 RPM, 6695 m³/h LWAE3G450SS-5MEW-03 (suction) and LWAE3G450ST-5MEW-04 (blowing) LWAE3G450SS-5MGW-05 (suction) and LWAE3G450ST-5MGW-06 (blowing) Low noise versions: LWAE3G450SS-5MEW-09 (230V, 1670 RPM, 5871 m³/h, 67 dB) Ultra quiet model: LWAEG3450SS-5PEW-10 (1080 RPM, 4266 m³/h, only 52 dB)

5. Rugged Design for Harsh Environments.

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.

Are EC axial fans noisy?

Longwell EC axial fans are designed with noise reduction features, maintaining a low noise level even at high speeds, making them ideal for noise-sensitive environments.

What’s the difference between EC axial fans and traditional AC fans?

EC axial fans use electronically commutated motor technology, which provides higher energy efficiency and precise speed control, making them more efficient and flexible than traditional AC fans.
