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.

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.

- 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.
