The R1G133-AA65-02 from EBM-Papst is a DC-powered centrifugal fan with backward-curved blades, designed as a complete motorized impeller with a 133 mm diameter. It is powered by a built-in 48 V DC EC motor and delivers high air volume with low energy consumption – perfect for compact installations where efficiency is crucial.
The fan is ideal for medical equipment, industrial cooling, telecom equipment, and other applications where quiet, precise, and energy-efficient air circulation is required. The integrated 0–10 V DC/PWM control input makes it easy to integrate into existing control systems.

| Motor frame | The fan is designed as a built-in component and is mounted with strength class 8.8 screws. The maximum screw clearance is 6 mm according to the product drawing. The mounting position is optional. The screws must be secured against accidental loosening, e.g. with self-locking screws. An inlet cone (part number 09566-2-4013) is available as an accessory and is not included in the delivery. |
| Impeller | The fan impeller is made of PA plastic and has 7 blades. The direction of rotation is clockwise when viewed from the rotor. The fan size is 133 mm and the rotor surface is thick-film passivated. The fan impeller is balanced for smooth operation and should be kept clean to avoid vibrations that can shorten its lifespan. |
