| Airflow at 0 Pa | 410 lpm m³/h |
| Speed | 40,000 rpm |
| Power | 43 W |
| Voltage | 24V DC VAC |
| Motor frame | The unit is designed for mounting with plastic screws with a diameter of 2.5 mm and a maximum screw depth of 6 mm. The mounting points are arranged with a center-to-center distance of 120 × 120 mm. The compact design and low weight of 135 grams facilitate integration into portable and medical devices. |
| Impeller | The fan impeller is a centrifugal impeller that provides increasing flow and pressure rise at increasing rotational speed. At a nominal speed of 40,000 rpm, an airflow of 410 l/min (14.5 cfm) is achieved. The fan can handle static pressure increases of over 5,000 Pa. The design is extremely compact with outer dimensions of around 69.5 × 69.5 mm and is optimized for respirator applications with rapid pressure variations between 400 Pa and 2,000 Pa. |
| Motor type | The motor is a DC-powered motor designed for compact centrifugal fans. The nominal voltage is 24 V DC with a voltage range of 7–30 V. The nominal speed is 40,000 rpm, which allows for very dynamic power development. The motor's compact design and low weight of only 135 grams make it suitable for medical technology applications such as ventilators. The service life is specified as 22,500/7,500 hours (standard) and up to 50,000 hours (maximum). |
