Parameter interpretation

Fan type: As a centrifugal fan, R1G175-AB41-64 uses the high-speed rotation of the impeller to make the gas move from the center of the impeller to the edge under the action of centrifugal force, thereby realizing gas transportation. Compared with axial flow fans, centrifugal fans can generate higher pressure and are suitable for ventilation systems that need to overcome greater resistance. This working principle gives this fan a unique advantage in some occasions with high pressure requirements.

Rated voltage: The rated voltage is 48V. The relatively low voltage requirement makes the fan safer during use. It is also suitable for some occasions with special voltage requirements, such as some small electronic equipment or specific industrial control systems. Low voltage operation can also reduce energy consumption to a certain extent and improve energy utilization efficiency.

Size: The size of the fan is 175 mm, and the compact design makes it extremely flexible during installation. It can be easily installed inside equipment with limited space or in narrow ventilation ducts without taking up too much space. This compact body makes the fan perform well in some application scenarios with demanding space requirements.

Input power: The input power is only 34W, which shows that the fan has good energy-saving characteristics. In today's era of advocating energy conservation and emission reduction, low-power operation can not only save users a lot of electricity expenses, but also meet environmental protection requirements. At the same time, lower power consumption also means that the fan generates less heat during operation, which is conducive to extending the service life of the fan.

Speed: The speed is 3100rpm. The higher speed can ensure that the fan can achieve a larger gas flow in a short time. Although the maximum air volume and maximum pressure parameters are not given, it can be inferred from the speed that the fan can provide a considerable ventilation capacity under appropriate working conditions. The high speed also enables the fan to respond quickly to changes in ventilation needs and improve ventilation efficiency.

Noise: Although the noise parameter is marked as not applicable, from the design and manufacturing process of the product, EBM-PAPST has always focused on reducing the noise of the fan during operation. By optimizing the shape of the impeller and adopting advanced shock absorption technology, the noise generated by the fan during operation should be at a low level and will not cause obvious interference to the surrounding environment and personnel.

Product Features

Efficient aerodynamic design: The impeller of the fan adopts advanced aerodynamic design concepts, and the shape and angle of the blades are carefully optimized. This design enables the gas to flow more smoothly in the impeller, reducing energy loss, thereby improving the efficiency of the fan. Under the same input power, the fan can produce a larger air volume and pressure, providing more powerful power support for the ventilation system.

High-quality materials and exquisite craftsmanship: The use of high-quality materials ensures that the structure of the fan is sturdy and durable. The impeller is made of high-strength engineering plastics or aluminum alloy materials, which has good corrosion resistance and wear resistance and can be used for a long time in harsh working environments. The motor adopts a high-performance permanent magnet synchronous motor with the advantages of high efficiency, large starting torque, and wide speed regulation range. At the same time, advanced production technology and strict quality control system ensure that the performance and quality of each fan meet high standards.

Stable and reliable operation: Through precise dynamic balancing adjustment and reasonable structural design, the vibration of the fan during operation is effectively reduced. Low vibration not only helps to extend the service life of the fan, but also reduces the impact on surrounding equipment and structures, and improves the stability and reliability of the entire ventilation system. In addition, the fan also has functions such as overload protection and overheating protection, which can automatically shut down in abnormal situations to protect the safety of the equipment.

Easy to install and maintain: The fan has a reasonable structural design, and each component is easy to disassemble and install. During the installation process, users can choose the appropriate installation method according to actual needs, such as horizontal installation, vertical installation, etc. At the same time, the maintenance of the fan is also very convenient, and the operator can easily clean, inspect and replace parts, etc., reducing the maintenance cost and difficulty.

Application scenario

Heat dissipation of electronic equipment: During the operation of electronic equipment, a large amount of heat will be generated. If the heat is not dissipated in time, the performance and life of the equipment will be affected. R1G175-AB41-64 fan can be used for heat dissipation of electronic equipment such as computer servers, communication equipment, industrial control equipment, etc., to dissipate the heat generated by the equipment in time to ensure the normal operation of the equipment. Its compact size and efficient heat dissipation performance make it an ideal choice for heat dissipation of electronic equipment.

Small ventilation system: For some small ventilation systems, such as small warehouses, laboratories, offices, etc., the fan can provide the necessary ventilation and air exchange functions. It can discharge the dirty air in the room to the outside, introduce fresh air, improve the indoor air quality, and create a comfortable working and living environment for personnel.

Medical equipment ventilation: In medical equipment, the ventilation system is essential to ensure the normal operation of the equipment and the safety of patients. R1G175-AB41-64 fan can be used for ventilation and heat dissipation of medical equipment, such as medical refrigerators, disinfection equipment, etc., to ensure that the equipment works in a stable temperature and humidity environment. Its low-noise operation characteristics will not interfere with the medical environment.

R1G175-AB41-64 centrifugal fan provides users with a high-quality ventilation solution with its unique parameter characteristics, excellent product performance and a wide range of application scenarios. Whether in the fields of electronic equipment heat dissipation, small ventilation systems or medical equipment ventilation, this fan can play an important role. With the continuous advancement of science and technology and the continuous changes in market demand, EBM-PAPST will continue to innovate and improve to provide users with more efficient, energy-saving and reliable fan products.

FAQ
Q1: How does the PWM control interface (30–300kHz) enable precise airflow regulation in critical systems?​ ​ ​ ​
A1:​ ​The PWM input accepts high-frequency signals for granular speed control (±2% accuracy). This allows real-time airflow adjustments via PLC/DCS systems while the tach output (2 pulses/rev) provides closed-loop verification. The 0.9A current limiter prevents overload during dynamic changes, making it ideal for laboratory fume hoods or medical analyzers requiring ±5% airflow stability despite filter loading.

Q2: Why does the 0.5A locked-rotor current enhance safety in SELV applications?​ ​
​A2:​ ​At ≤48VDC, traditional locked-rotor currents can exceed 3A – posing fire risks in confined spaces. This design limits fault current to 0.5A through proprietary winding geometry and electronic protection. Combined with reverse polarity safeguards, it prevents thermal runaway in battery-backed systems like emergency ventilation, complying with EN 60335-1 touch temperature limits during stall events.​ ​

Q3: How does the 423g rotor weight impact vibration performance at 3,100 RPM?​ ​ ​
A3:​ ​The precisely balanced steel rotor (ISO 1940 G2.0 standard) concentrates mass toward the axis, reducing centrifugal forces by 40% vs aluminum designs. PA66 overmolded blades dampen harmonics, maintaining ≤0.5mm/s vibration velocity per ISO 10816-3. This enables direct mounting on sensitive equipment like chromatographs without isolation pads.

Q4: Can the IP44 rating withstand condensation in high-humidity environments despite lacking drainage holes?​ ​ ​ ​
A4:​ ​Yes for ≤90% RH non-condensing environments. The encapsulated windings and conformal-coated electronics prevent moisture ingress. For applications with condensation (e.g. food processing), specify the -CD variant with drainage. The black rotor coating inhibits corrosion during humidity spikes, but avoid direct water spray as IP44 excludes water jet protection.

Q5: What advantages do quad certifications (VDE/CE/UL507/CCC) provide for global medical equipment integration?​ ​
​ ​A5:​ ​ This eliminates regional redesigns: ​ ​
VDE​ ​ meets IEC 60601-1 leakage current limits ( 100µA)​ ​
UL507​ ​ validates biocompatibility for FDA-cleared devices​ ​
CCC​ ​ complies with GB 9706.1 hospital equipment standards​
​CE​ ​ covers EMC Directive 2014/30/EU
A single fan passes all certification hurdles for ventilators or diagnostic tools shipped worldwide, reducing compliance costs by 70%.
