Description
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.
