| Airflow at 0 Pa | 870 m³/h |
| Speed | 1400/1620 rpm |
| Power | 72 W |
| Frequency | 50/60 Hz |
| Voltage | 230V AC VAC |
| Motor frame | The fan is designed as a panel fan with a size of 250 mm and is supplied with a round full nozzle. The casing is made of pre-galvanized sheet metal coated with black plastic (RAL9005), and the guard grille is made of phosphated steel with a black plastic coating. The standard mounting position is with the shaft horizontal or the rotor downwards; mounting with the rotor upwards is possible on request. Condensate drainage holes are located on the rotor side. The fan's weight is 2.9 kg. |
| Casing | sheet, pre-galvanised and plastic-coated in black (RAL9005), round |
| Impeller | The fan impeller has 5 straight blades (A-series) made of sheet metal, painted black. The airflow direction is A and the rotation direction is clockwise when looking at the rotor. In free air operation and at 50 Hz, the fan delivers 870 m³/h, and at 60 Hz, 1005 m³/h. The fan impeller surface is black lacquered for corrosion protection. |
