Technical references
Can the external fan also be supplied in special dimensions or configurations?
We can manufacture the external fan according to your specifications starting from just 1 piece. Please use our inquiry datasheet for this purpose.
What is the delivery time?
Standard sizes can be ordered in small quantities from stock. Custom-made external fans generally have a delivery time of 3–4 weeks.
Can I get the external fans with a finished coating?
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.
