In-wall fans with 400 Volt
What Distinguishes 400 Volt Fans from 230 Volt Models?
While 230 Volt wall-mounted fans are mostly used in smaller rooms or for standard applications, 400 V models are designed for demanding requirements:
- Higher Air Flow Rate: Effortlessly moves large air volumes in workshops, halls, or warehouses.
- Continuous Duty Rated: The three-phase motor operates extremely smoothly and with low wear, even under continuous load.
- High Efficiency: Due to even phase distribution, 400 V motors consume relatively less energy at high outputs.
Applications of 400V Wall-Mounted Recessed Fans
These fans are installed directly into exterior walls or shafts to ensure rapid air exchange in the presence of moisture, heat, dust, or odours. Typical installation areas include:
- Production halls and workshops
- Warehouse and logistics centres
- Agricultural buildings and livestock barns
- Commercial kitchens and technical equipment rooms
Key Features & Selection Criteria
| Criterion | What You Should Consider |
|---|---|
| Air Flow Rate (m³/h) | Choose the air volume based on the room size and required air exchange rates. |
| Speed Control | 400 V motors can often be precisely regulated via frequency inverters or step transformers. |
| Protection Class (IP) | Models with IP54 or IP55 are required for humid or dusty environments. |
| Noise Level | Pay attention to the dB(A) values if work is regularly carried out in the room. |
Important Installation & Safety Note
Please note: For safety reasons, the connection of 400 Volt three-phase devices must be carried out exclusively by a qualified electrician.
