Historical listing photographs

The added close-ups are cropped details from the same historical listing photograph. They show the pictured fan label and impeller, and the upper coloured leads and black cable. The original view already cuts off parts of the outer ring and wire ends; these details do not recover a complete outline or harness.

The retained box photograph shows several red fans for historical context. It does not verify the sale quantity or current stock. Confirm the actual supplied unit, complete harness and connector pinout before ordering.

ebm-papst R1G190-AC11-52 Centrifugal Fan

This motorized impeller is marked R1G190-AC11-52. The manufacturer operating instructions specify a 190mm size, nominal 48V DC supply, 71W power consumption, 1.65A current draw and 3200rpm under the stated free-air test condition.

Key Selection Points

  • Full model: R1G190-AC11-52.
  • Nominal size: 190mm; consult the product drawing for mounting and overall clearance.
  • Nominal voltage: 48V DC; voltage range: 36-57V DC.
  • Electrical input: 71W and 1.65A. The pictured label separately identifies 52W output.
  • Manufacturer documentation lists a tach output and 0-10V DC / PWM control input; verify the connection diagram and supplied cable assembly.

Replacement Selection Questions

Is 52W the electrical input power? No. The label distinguishes input and output; the manufacturer specifies 71W power consumption.

Does 3200 mean the frame is 32mm? No. It is the nominal rotational speed in rpm. The documented fan size is 190mm.

Is a matching diameter enough for replacement? No. Compare mounting, axial clearance, airflow requirements, voltage and control connections.

Is this a standalone guarded appliance? No. It is a built-in component; follow the manufacturer installation and guarding instructions.

Common checks for replacement cooling fan sourcing.

Can you help match an old fan?

Yes. Send photos of the fan label, connector and equipment so we can check model, voltage, frame size and wiring.

Can I use a different brand as a replacement?

Often yes, but only after confirming frame size, electrical rating, airflow requirement, bearing type, connector and wire sequence.

What information is needed for a bulk quote?

Send part number, quantity, target lead time, connector or cable requirements and shipping destination.
