Frequently asked questions
Can I run it from a 12 V supply?
The fan is rated for 24 V DC. Running it at a lower voltage reduces speed and airflow and may prevent reliable starting, so use a 24 V DC supply as specified.
How should I wire the fan?
Connect the positive lead to +24 V and the negative lead to ground. Lead colours vary between fan models, so confirm the wire assignment in the supplier's datasheet before powering it.
