| Motor frame | The housing is made of cast aluminum and measures 119 x 119 x 38 mm. The fan has mounting holes with a diameter of 3.7 mm (±0.15 mm) for the NXU version. The unit weighs 400 g, is UL approved, and has an IP68 rating for use in demanding environments. |
| Casing | cast aluminium, square (119 x 119 x 38 mm) |
| Impeller | The fan impeller is made of glass-fiber reinforced PA composite for high durability and corrosion resistance. It rotates clockwise when viewed from the rotor side and draws air in over the struts (air intake over struts). At rated voltage, an airflow of 99 CFM (approx. 168 m³/h) is achieved at a sound pressure level of 48.5 dB(A). |
| Bearing type | ball bearing |
| IP class | IP68 |
| Motor protection | reverse polarity and lock-out protection |
| Rotation direction | clockwise, viewed from the rotor side |
| Motor type | The motor is a DC motor with reverse polarity and lock protection. It is fully encapsulated according to IP68 standards, which means that the electronics and windings are completely potted for maximum protection against water and dust. The motor delivers 5.6 W at 24 V DC with a voltage range of 12–29 V DC. The operating temperature range is -20 to +75 °C. |
