Frequently asked questions
What voltage does it need?
It is rated for DC 24 V. Running it at other voltages is outside the listed rating.
How do I set the airflow direction?
The fan rotates counterclockwise as viewed from the blades, so mount it so the air flows the way you need. The listing does not give wire colours, so check the leads before wiring.
