Industrial centrifugal blower
The Ebm-Papst R1G225-AF11-21 is a 225mm backward-curved centrifugal fan built for 48VDC systems. It targets integrators who need directed airflow through ducts or restrictive enclosures rather than open-case circulation.
Sustained thermal behaviour
Ball-bearing construction and Class B insulation support continuous operation from -25°C to 60°C ambient. The motor draws 2.2A at 95W across a 36–57VDC range, maintaining 2700RPM without thermal throttling during extended duty cycles.
Installation constraints
The 1.5kg unit requires secure mounting to handle vibration from the 74mm motor core. IP44 rating protects against splashing water but not immersion. Wiring must accommodate 48VDC at 2.2A; the fan includes no speed-control interface or connector.

Questions about this item
How much acoustic and thermal load does the 95 W, 2700 RPM centrifugal fan add when running continuously?
The motor draws 2.2 A at 48 VDC for 95 W power consumption at 2700 RPM; ball-bearing construction and IP44 rating help sustain long-term operation within the -25 °C to 60 °C ambient range.
What 48 VDC power source and wiring must I already have to run this fan?
A supply delivering 36–57 VDC capable of at least 2.2 A is required; the fan terminates in bare leads for direct connection to that source.
Will the 225 mm backward-curved impeller clear the same cut-out as the 74 mm motor frame I am replacing?
The fan housing measures 225 mm overall while the motor frame is 74 mm; verify your chassis cut-out and mounting holes match these dimensions before installing.
