产品特点

Efficient EC Cooling

R3G450-PA31-36 is an ebm-papst EC centrifugal fan for HVAC and Ventilation, where controlled heat removal and airflow management must match the actual duty point. Its model-specific format supports OEM builds, retrofit planning and replacement sourcing.

Documented selection points include 3`380-480 V supply, 4450 W input, 450 mm size, up to 14310 m3/h airflow. These values support electrical, envelope and duty-point comparison.

For procurement, verify voltage, duty point, dimensions, connector and mounting. Correct sizing and clear airflow paths support stable operation, controlled noise and long service life. Confirm speed control, IP protection and approvals in the exact-model datasheet.

应用行业

AC to EC Replacement — R3G RadiPac EC Centrifugal

The ebm-papst R3G450-PA31-36 from the RadiPac EC Centrifugal series is a direct energy-saving replacement for legacy AC fans including R4D, R2D. Key benefits:

35-50% energy savings — EC motor variable speed matches airflow demand precisely
Identical mm mounting — no ductwork modification needed
0-10V/PWM speed control — integrates with Building Management Systems
40,000+ hour bearing life — double the typical AC fan lifespan

R3G EC fans operate at V with W rated power. When replacing AC models, wire the 0-10V control signal alongside the standard three-phase power cable.

常见问题

How can noise be managed when using the R3G450-PA31-36?

The table lists 78 dB. Use unobstructed airflow, secure mounting and suitable isolation where required.

Is the R3G450-PA31-36 easy to maintain?

Provide service access, keep the airflow path clean, inspect wiring and mounting, and investigate abnormal noise or vibration before continued use.

Does the R3G450-PA31-36 support speed control?

Control capability and input method must be confirmed in the exact-model datasheet and wiring diagram; do not infer them from the fan family alone.

Can the R3G450-PA31-36 run continuously in 24/7 equipment?

Continuous operation must remain within the published electrical, thermal and aerodynamic limits; confirm the exact datasheet and system conditions.
