R3G630-PC08-03 | ebm-papst 400V Centrifugal Fans

Name: R3G630-PC08-03 | ebm-papst 400V EC Centrifugal Fan for Data Centers
Brand: ebmpapst

Product Overview

The ebmpapst R3G630-PC08-03 is a high-performance 630 mm EC centrifugal fan engineered for demanding industrial ventilation, HVAC systems, air handling units (AHUs), refrigeration equipment, data centers, cleanrooms, and energy-efficient cooling applications. Delivering a maximum airflow of 12,470 CFM and a maximum static pressure of 1,000 Pa, it is designed to meet the requirements of high-airflow and high-pressure systems while maintaining exceptional operating efficiency. Powered by an advanced 400 V EC motor with a rated speed of 1,500 RPM, the fan combines outstanding aerodynamic performance with significantly lower energy consumption compared with conventional AC fans. Designed for 24/7 continuous operation (S1 duty), it features high-quality ball bearings, Class F insulation, integrated thermal overload protection, soft-start functionality, motor current limitation, and undervoltage and phase-failure detection, ensuring reliable long-term performance and minimizing downtime. The integrated intelligent electronics support RS-485 MODBUS RTU communication, an integrated PI controller, configurable I/O, alarm relay, LED status indication, and external parameterization via a 15–50 VDC input, allowing seamless integration with BMS, PLC, and industrial automation systems for precise speed control and remote monitoring. With an IP55 protection rating, a die-cast aluminum electronics housing, painted steel rotor, and aluminum sheet impeller, the R3G630-PC08-03 is well suited for harsh industrial environments involving dust, humidity, and demanding operating conditions. It supports transport and storage temperatures from -40°C to +80°C, while optional low-temperature bearing configurations are available for continuous refrigeration applications below -25°C. Despite its high output capability, the optimized backward-curved impeller and EC motor technology help reduce vibration and maintain a relatively low operating noise level of 74 dB, contributing to a quieter and more efficient working environment. Installation is straightforward thanks to its flexible mounting options, integrated terminal box, and maintenance-friendly brushless EC motor design, which significantly reduces service requirements throughout its operational life. The fan complies with major international standards, including CE, UL, CSA, EAC, EN 61800-5-1, and EN 61000 EMC requirements, ensuring global compatibility and dependable product quality. By combining high efficiency, intelligent control, long service life, low maintenance requirements, and reduced energy consumption, the ebmpapst R3G630-PC08-03 helps lower the total cost of ownership (TCO), making it an ideal solution for OEM manufacturers and industrial users seeking a reliable, energy-saving EC centrifugal fan for mission-critical ventilation and cooling systems.

Frequently Asked Questions

What is the lead time for the R3G630-PC08-03?

Standard lead time is4-6 weeksfor bulk orders. Limited stock available for immediate shipment (1-2 units). Contact us for current inventory status.

What control interfaces are supported?

The fan supports0-10V DC analog inputandPWM inputfor speed control, withtachometer output(10V DC, max. 1.1mA) for speed monitoring. MODBUS RTU interface is also available for BMS/DCIM integration.

What's the difference between R3G630-PC08-03 and other R3G630 variants?

The R3G630 series includes multiple variants optimized for different applications (e.g., RB32 for refrigeration, PC08 for high-CFM data center use). The PC08-03 specifically features a higher airflow curve and is tuned for data center cooling with lower noise characteristics. Contact us for a comparison chart.

Can I use multiple fans in parallel?

Yes. The built-in Active Power Factor Correction (PFC) ensures stable parallel operation without interference between units. This is a key advantage for multi-fan data center cooling arrays.
