2. Miniature Radial Blowers

2.1 Product Parameters and Dimensions

Blower models vary in size, typically ranging from approximately 50 mm to 95 mm in dimensions. Housing and impellers are made from medical-grade thermoplastics or modified PPE reinforced with fiberglass, ensuring durability and biocompatibility for medical applications.

2.2 Technical Data (@ Nominal Voltage)

Electrical parameters include current (mA) at free blowing, working point, and static conditions; phase inductance (mH); phase-to-phase resistance (Ohm); and nominal voltage (12 V, 24 V, with 48 V on request).
Mechanical parameters cover rotational speeds (rpm), rotational inertia, and mass.
Performance metrics include airflow volume (l/min), pressure (Pa), and power consumption (W) at working points.

2.3 Motor Types

Models feature three-phase brushless motors, either with or without Hall sensors. Some variants include internal drivers for enhanced control.
