What sizes are available?
Frame sizes range from 20mm to 200mm. See the complete model table above for the full breakdown by size, voltage and variant family.
What voltage options do you offer?
5V, 12V, 24V and 48V, depending on the series. Most frame sizes offer more than one voltage. Check the model table for what's published at your size.
What is the difference between ball bearing and sleeve bearing?
Bearing configuration affects both operating temperature range and expected service life. See Sleeve Bearing vs. Ball Bearing Fan Life for the full comparison.
Do you offer PWM speed control?
PWM speed control is available as a configurable option (20–30kHz, six standard curve patterns). It's not standard on every model. Confirm when you place your order.
Can these fans run on 48V?
Yes. Several series across this range publish 48V variants, including 60×60×38mm, 80×80×38mm, 120×120×38mm, 150×150×50mm and selected larger frames.
What is the expected lifespan?
Expected service life depends on bearing configuration. See our bearing life reference for the full breakdown: Sleeve Bearing vs. Ball Bearing Fan Life
What is the MOQ for OEM orders?
Standard catalog orders have a MOQ of 10 units. OEM custom-specification and private-label orders have a MOQ of 50 units. There is no minimum for samples. See Commercial Terms above for full order terms.
Can you customize voltage, connector, or fan configuration?
Electrical, control and connector requirements can be reviewed case by case. Non-standard frame dimensions outside this range require a separate engineering and tooling evaluation. Send your requirement and we'll confirm what's involved.
What certifications do these fans carry?
CE marking applies across the range, and our facility holds ISO 9001 certification at the company level. Specific certificate numbers and the certified entity are available on request.
How do I choose the right size and voltage for my application?
Start with your required airflow and static pressure, then check frame size, system voltage, bearing/control needs and noise budget against the model table above, or send your requirement directly for an engineering recommendation. You can also use the DC Brushless Fan Selector to filter by your exact requirement.
