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.

Application Industry

HVAC Systems

Applied in HVAC and ventilation equipment to move and circulate air through the system. This industrial fan supports heat exchange, indoor-air management and reliable operation of climate-control equipment.

Air Purification

Applied in air-purification and clean-air equipment to move air through filters and internal passages. Stable airflow supports filtration performance and reliable operation of the complete system.

Product Insights

AC to EC Replacement — R1G EC Centrifugal

The ebm-papst R1G220-AB73-99 from the EC Centrifugal series is a direct energy-saving replacement for legacy AC fans including 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

R1G 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.
