Core advantage 

1. Strong Performance, Efficient Heat Dissipation

• Ultra‑high airflow range: Single fan delivers 2950–17933m³/h; the A630M.A014 model reaches up to 17933m³/h, supporting high‑power cooling for energy storage containers.

• Excellent static pressure curve: Stable airflow under medium‑to‑high static pressure, maintaining high heat exchange efficiency even in restricted air ducts, suitable for liquid‑cooled and air‑cooled energy storage systems.

• Wide power coverage: 273–2550W, matching small cabinet cooling and large‑container centralized ventilation for various power‑density setups.

2. Metal Impeller, Sturdy & Long‑Life

• Metal impeller structure: Resists deformation, high temperature and dust impact; stable under long‑term high‑speed operation with far longer service life than plastic impellers.

• Reliable AC motor: Mature industrial‑frequency drive, wide voltage compatibility 230/380/400V, 50/60Hz, direct grid connection, simple control and low failure rate.

• Harsh environment adaptability: Continuous high‑speed operation and vibration resistance, suitable for long‑term duty in outdoor and semi‑outdoor energy storage cabinets.

3. Low‑Noise Design, Site‑Friendly

• Optimized noise level: 63–76dB(A) across models; larger fans feature lower noise, complying with regulations for energy storage stations near residential and park areas.

• Aerodynamic optimization: Reduces turbulence and eddies, boosting airflow while lowering wind noise for a better station environment.

4. Complete Specifications, Ready for Installation

• Full size range: A300/A450/A500/A550/A630 diameters fit standard energy storage cabinet openings.

• Standardized mounting: Universal 4‑hole / 6‑hole fixing patterns and consistent flange dimensions for fast replacement and new projects.

• Multi‑voltage option: 230V/380V/400V, 50/60Hz dual‑frequency, compatible with global power grids and project configurations.

5. Customized for Energy Storage, Safe & Stable

• Perfect thermal management: High airflow + stable static pressure rapidly removes heat from battery clusters, PCS and converters, ensuring system safety and cycle life.

• Robust structure: Metal impeller and heavy‑duty housing prevent foreign objects and impact, improving operational safety in energy storage containers.

• Long‑term reliability: Minimal maintenance required, reducing operation costs and downtime risks for energy storage stations. 

FAQ

Q1: What energy storage scenarios are these metal impeller AC axial fans suitable for?

A: Designed exclusively for energy storage thermal management, they are fully compatible with containerized energy storage, cabinet-type energy storage, and residential/commercial energy storage cabinets. They efficiently dissipate heat from core components such as battery clusters, power conversion systems (PCS), and power converters, and support 24/7 continuous operation in outdoor and semi-outdoor energy storage stations.

Q2: What are the core advantages of metal impellers over traditional plastic impellers?

A: The key differences lie in durability and working condition adaptability:

• Superior resistance to deformation, high temperatures, and dust impact, eliminating the risk of fatigue deformation during long-term high-speed operation

• Significantly longer service life than plastic impellers, especially ideal for the harsh high-temperature and dusty environment inside energy storage cabins

• Higher structural strength to withstand greater wind pressure and vibration, reducing operational failure rates

Q3: What voltages and frequencies do the fans support? Can they adapt to power grids in different regions worldwide?

A: They support 230V/380V/400V 50Hz multi-voltage input, covering domestic and most overseas industrial power grids. The A500M.A002 model additionally offers a 460V 60Hz version, which can be directly adapted to the power grid standards of North America, Japan, South Korea and other regions without additional transformers.

Q4: Is the installation complicated? What daily maintenance is required?

A: Installation is straightforward with a standardized 4-hole/6-hole mounting design and uniform flange dimensions, matching the opening specifications of mainstream energy storage cabinets. It is plug-and-play, enabling rapid deployment for both new projects and old equipment replacement. No frequent daily maintenance is required; only regular cleaning of dust accumulation on the impeller surface is needed, greatly reducing the operation and maintenance costs of energy storage stations.

Q5: How to select the appropriate fan model for my energy storage system?

A: Selection is mainly based on three dimensions:

1. Cooling requirement: Choose the A300 series (2950-3239 m³/h) for low-power cabinets, and the A550/A630 series (11469-17933 m³/h) for large containerized energy storage

2. Installation size: Full diameters of A300/A450/A500/A550/A630 are available to match different cabinet openings

3. Power supply condition: Select the corresponding model according to the on-site grid voltage to ensure stable direct-drive operation
