The EBM-Papst 9591904122 is a compact DC centrifugal fan with forward-curved blades, measuring 51 × 51 × 15 mm. The fan is designed for energy-efficient blowing, where air flows in axially and out radially, providing a maximum airflow of 9.6 m³/h and a maximum static pressure of 170 Pa.
With its compact size and PWM control (21–28 kHz), the fan is ideal for electronic equipment, medical devices, and other applications with limited space and demands for precise speed control.

Datasheet (PDF) - download| Product attribute | Value |
|---|---|
| Airflow at 0 Pa | 9.6 m³/h |
| Speed | 6,700 rpm |
| Power | 4.3 W |
| Voltage | 24V DC VAC |
| Motor frame | The fan has dimensions of 51 × 51 × 15 mm and weighs 36 grams. Mounting is done via a flange in both mounting corners with ISO 4762 M4 screws (degreased, without washer). The casing is made of plastic and the shaft's mounting position can be arbitrary. |
| Casing | plastic |
| Impeller | The fan impeller is made of plastic and rotates counter-clockwise when viewed from the rotor side. The fan is a blower type (centrifugal fan) where the air flows in axially and out radially. With free airflow and 100% PWM, a maximum airflow of 9.6 m³/h and a maximum static pressure of 170 Pa are achieved. |
| Bearing type | ball bearing |
| Rotation direction | counter-clockwise |
| Motor type | The motor is a DC motor with electronic speed control via a PWM signal (21–28 kHz, typically 25 kHz). The rated voltage is 24 V DC, with an allowed voltage range of 14–28 V. The motor has reverse polarity protection via a rectifier diode and automatic restart in case of a locked rotor. The electronics allow speed control from 20% up to 100% PWM duty cycle after startup. |
