Technical specifications
| 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 measures 51 × 51 × 15 mm and weighs 36 grams. Mounting is done via a flange in both mounting corners using ISO 4762 M4 screws (degreased, without washer and without additional support). The housing is made of plastic and the mounting position for the shaft can be arbitrary. |
| Casing | plastic |
| Impeller | The impeller is made of plastic and rotates counter-clockwise when viewed from the rotor side. Air is drawn in axially and discharged radially, which is typical for a centrifugal impeller. The fan delivers a maximum free air flow of 9.6 m³/h and a maximum static pressure of 170 Pa at nominal voltage. |
| Bearing type | ball bearing |
| Rotation direction | counter-clockwise |
| Motor type | The motor is a DC motor with a nominal voltage of 24 V and a voltage range of 14–28 V. At nominal voltage, the motor consumes 4.3 W with a current draw of 180 mA. The motor has automatic restart at locked rotor and is protected against reverse polarity via a rectifier diode. The speed at free air flow and nominal voltage is 6,700 rpm. |
