|---|---|
| Airflow at 0 Pa | 238 m³/h |
| Speed | 11,000 rpm |
| Power | 30W |
| Voltage | 24V DC VAC |
| Motor frame | The housing is square and made of plastic, with dimensions 92 × 92 × 38 mm and weighing 0.280 kg. Mounting is via four flanged corners with ISO 4762 M4 screws (degreased, without washer) with a maximum tightening torque of 30 Ncm. The mounting position is arbitrary. |
| Casing | plastic, square |
| Impeller | The fan impeller is made of plastic and has an axial flow design. It blows air over the fins and rotates clockwise when viewed from the rotor side. At 11,000 rpm free-blowing, a maximum airflow of 238 m³/h and a maximum static pressure of 645 Pa are achieved. |
| Bearing type | ball bearing |
| Motor protection | electronic restart on blocking |
| Rotation direction | clockwise (viewed from the rotor side) |
| Motor type | The motor is a DC motor with electronic speed control and integrated reverse polarity protection via diode. Blockage protection is provided by an electronic restart with a blockage cycle of 0.5 s/10.0 s. The motor is designed for a nominal voltage of 24 V DC with a voltage range of 12–27.6 V. The inrush current is 4,800 mA and the locked rotor current is approximately 4,300 mA. |
