Germany Brand Centrifugal Blower
The Fans R3G355-AY43-21 is a new ebm-papst centrifugal blower built for HVAC systems that need high-volume air intake. Its backward-curved impeller reaches 35000 m³/h airflow at 2450 RPM while drawing 6.0 A at 230 VAC. The unit operates on single-phase AC power across a 200–277 V range at 50/60 Hz.
Steel Housing With External Rotor Motor
A sturdy steel plate enclosure protects the compact external rotor motor rated at 1400 W. The design eliminates the need for a separate scroll housing, simplifying duct integration and reducing installation footprint. Forced electronic cooling and 100 % speed control via analog or serial interface allow precise airflow matching. Plug-and-play wiring and matched open-loop components speed up commissioning.
Verify Voltage Phase And Temperature Range
Confirm the supply is single-phase AC within 200–277 V at 50 or 60 Hz before wiring. Ensure the mounting location stays between -25 °C and 50 °C ambient. Check that the control system can provide the required analog or serial signal for speed regulation. Validate duct dimensions and static pressure requirements against the 355 mm impeller performance curve.

Questions about this item
What voltage range and frequency does the AC motor accept?
The motor runs on single-phase AC from 200 to 277 V at 50 or 60 Hz, with a nominal 230 V rating.
What are the physical dimensions and mounting style of this blower?
It is a 355 mm round unit with a compact external-rotor motor and sturdy steel plate housing, designed for direct mounting without a separate scroll casing.
How is the fan speed controlled and what wiring step is often missed?
Speed is adjustable 0–100 % via an analog or serial interface; the control signal wire must be connected for variable-speed operation, otherwise the fan runs at full 2450 rpm.
