  • Dual-speed motor runs at 2750 or 3100 rpm for flexible performance
  • 380 V AC input suits industrial and server installations

Industrial-grade 380 V AC cooling

The 172 × 172 × 51 mm frame houses a hydro-bearing motor rated for 380 V AC input. It delivers 198 to 235 CFM at 2750 to 3100 rpm while drawing 44 to 46 W. The unit weighs 945 g and operates from −30 °C to +75 °C.

Build integration and airflow role

Designed for industrial enclosures, rail vehicles, medical gear and similar high-voltage cabinets, it mounts directly to panels with standard 172 mm spacing. No external driver or low-voltage converter is required, freeing internal space for other equipment. Installers must provide 380 V AC supply wiring and appropriate circuit protection.

Thermal acoustic and power profile

Noise output ranges from 55 to 59 dB-A across the speed range, reflecting the high-volume airflow needed for dense heat loads. Power draw stays within 44 to 46 W, and the hydro bearing maintains consistent speed across the full −30 °C to +75 °C temperature span. Not suited for quiet desktop builds or low-voltage PC chassis.
