Information on the Type External Fan
The MW series external fans are available in multi-voltage versions designed for ambient temperatures from -40 °C to 60 °C. All units come with UL/CSA approval and feature IP66 protection class.
These industrial fans are available in sizes 250 to 315 and are specifically designed for operation in low ambient temperatures down to -40 °C.
Multi-Voltage Options (+/- 5 %)
- 3-phase 200–400 V Δ 50 Hz
- 3-phase 220–400 V Δ 60 Hz
- 3-phase 346–525 V Y 50 Hz
- 3-phase 380–575 V Y 60 Hz
Flexible Mounting and Customization
The screwed and interchangeable frames (connection adapters) can be modified to match motor connection dimensions, allowing for easy series installation and retrofit to external fan operation.

In the standard version, our external fan housings are delivered with a gray primer. On request, they can also be powder-coated in almost any common RAL color. Alternatively, manufacturing in stainless steel is also possible.
What supply voltage can I use to operate the external fans?
Most of our external fan types have a multi-voltage connection of 346–525 V, 50 Hz or 380–575 V, 60 Hz. Sizes 63–225 even include a single-phase connection.
Additional special voltages are available under the “Special Versions” section.
