Core advantage

1.Wide Voltage & Multi-Spec Compatibility for Full-Scenario Cabinet AC Needs

The series offers versions compatible with 110/230/380/460V power supplies, supporting both 50Hz and 60Hz grid environments. With impeller diameters ranging from 175mm to 225mm, airflow from 438 to 1328 m³/h, and power from 43.4 to 242W, it flexibly matches small cabinet precision air conditioners of various power levels, meeting diverse installation and power supply requirements.

2.High-Efficiency Cooling Performance for Cabinet Heat Loads

With a maximum speed of 3190 rpm and backward-curved centrifugal impeller design, the fans deliver stable high airflow within a compact footprint. They effectively penetrate heat zones even in high-resistance enclosed cabinet air ducts, quickly removing sensible heat from equipment, preventing local hotspots, and ensuring uniform and stable cabinet temperatures.

3.Energy-Efficient Operation to Reduce Long-Term Operating Costs

The series demonstrates excellent energy efficiency across different loads. For mainstream 230V models, power consumption is only 112-148W at airflow rates of 900-1110 m³/h, significantly reducing energy use compared to traditional fans. They also support speed regulation on demand, dynamically adjusting with the air conditioning system to eliminate unnecessary power consumption, ideal for 24/7 continuous operation.

4.Low-Noise Operation for Quiet Data Center Environments

Through aerodynamic optimization and precision dynamic balancing, the series controls noise levels between 60.8 and 71.8 dB(A). Mainstream 230V models operate as quietly as 60.8-68.6 dB(A), effectively reducing operational noise while maintaining airflow and static pressure, avoiding disturbances to data centers or office areas.

5.High Reliability & Long Lifespan for Year-Round Cabinet Operation

Equipped with maintenance-free bearings and reinforced insulation, these fans can operate stably long-term in fluctuating cabinet temperature and humidity environments. All models undergo strict dynamic balancing and aging tests, ensuring low vibration and failure rates. Designed for 24/7 continuous operation, they minimize downtime and maintenance, enhancing overall system reliability.

6.Compact & Modular Design for Easy Installation & Maintenance

Featuring a compact, volute-less backward-curved centrifugal structure, these fans fit easily into the limited space of small cabinets. They support multi-orientation installation without complex duct modifications. The modular design simplifies cleaning and maintenance, effectively reducing labor costs for installation and upkeep.

FAQ

Q1: What voltage and grid environments do these centrifugal fans support? Are they suitable for overseas projects?

A1: This fan series offers multiple voltage versions including 110V, 230V, 380V and 460V, compatible with both 50Hz and 60Hz power grids. They can directly meet the power supply requirements of cabinet precision air conditioners in different regions at home and abroad without additional power conversion modules, making overseas project adaptation much easier.

Q2: How effective is the cooling performance of these fans in small cabinets? Can they eliminate local hotspots?

A2: Equipped with backward-curved centrifugal impellers and a maximum speed of 3190 rpm, the fans deliver airflow ranging from 438 to 1328 m³/h. They effectively penetrate high-resistance air ducts inside cabinets, evenly dissipate equipment heat, prevent local hotspots, and ensure stable internal temperatures, perfectly matching the cooling demands of precision air conditioners.

Q3: What are the energy consumption and noise levels during 24/7 continuous operation?

A3: For mainstream 230V models, power consumption is only 112–148W at airflow rates of 900–1110 m³/h, significantly lower than traditional fans. Noise levels are controlled between 60.8–68.6 dB(A). Even with round-the-clock operation, they maintain low energy use and quiet performance without disturbing the data center or office environment.

Q4: Can the fans withstand the harsh conditions inside cabinets? Are they prone to frequent failures over long-term use?

A4: Featuring maintenance-free bearings and reinforced insulation, these fans undergo strict dynamic balancing and aging tests. They can operate stably in the enclosed, temperature- and humidity-fluctuating environment of cabinets, supporting year-round continuous operation with low failure rates and long service life. This minimizes downtime and maintenance, ensuring stable operation of the precision air conditioning system.

Q5: Are installation and maintenance complicated? Do they require modifications to the cabinet air ducts?

A5: With a compact, modular design, these fans support multi-orientation installation without complex air duct modifications, directly fitting the limited space of small cabinets. The modular structure also simplifies post-installation cleaning and maintenance, effectively reducing labor costs for both setup and upkeep.
