Frequently Asked Questions — DC Axial Fan 25489
What DC voltages are available for the 25489 fan?
The 25489 series covers 24 / 48 VDC. Custom voltages (e.g. 5V USB-powered or 48V telecom) are available for OEM projects.
What is the difference between sleeve and ball bearing versions?
Sleeve bearing is the most cost-effective and quietest option, best for horizontal mounting. Ball bearing lasts longer, tolerates any mounting angle and higher ambient temperature — recommended for 24/7 duty.
Can I order the 25489 with custom speed, connector or function options?
Yes. Custom RPM, voltage, lead connectors and function options (FG/RD signal, PWM/TC speed control, AS auto restart) are available. MOQ starts from 100 pieces and samples are supported for testing.
What is your lead time and warranty?
Standard models ship in 7–15 days; custom orders in 20–30 days. All fans carry a 2-year warranty with lifetime technical support.
