Selection Guide: Voltage, Airflow, Acoustic Optimization
For system integrators: choose 115V for North American installations, 230V for European/Asian markets. Higher static pressure (38mm depth) suits restrictive chassis. Our low-noise 25mm variant operates at just 28 dBA, ideal for office environments or medical labs.
Quality Management & Reliability Testing
Environmental Chambers
100% burn-in testing: 48h continuous operation at rated voltage and 70°C.
Vibration & Shock
Compliant with IEC 60068-2-6; suitable for transportation and mobile equipment.
L10 Life Expectancy
Dual ball bearing: 60,000 hours at 25°C; 40,000 hours at 60°C ambient.

FAQ of 120mm AC Fan
What are the standard dimensions and mounting configurations?
The standard frame sizes are:
120 x 120 x 25 mm (shallow profile, lower static pressure)
120 x 120 x 38 mm (deep profile, higher static pressure)
Mounting hole spacing is standardized at 104.8mm ± 0.5mm (center to center) with 4.5mm diameter mounting holes, ensuring compatibility with most industry-standard chassis and enclosures.
What voltage options are available?
We offer two primary voltage families:
115VAC (operating range: 100V – 125V, 50/60Hz) — preferred for North American markets
230VAC (operating range: 200V – 240V, 50/60Hz) — preferred for European, Asian, and other international markets
Dual-frequency (50/60Hz) capability ensures consistent performance regardless of regional power grids.
What airflow and static pressure ranges can I expect?
Performance varies by model depth and motor design:
25mm depth models: 65 – 86 CFM with static pressure of 0.17 – 0.24 inH₂O
38mm depth models: 105 – 118 CFM with static pressure of 0.32 – 0.38 inH₂O
For applications requiring higher pressure (e.g., filter-equipped enclosures or dense chassis), the 38mm depth series is recommended.
What is the noise level?
Noise levels range from 28 dBA (low-noise 25mm model) to 46 dBA (high-performance 38mm model). Acoustic performance depends on:
Operating voltage and frequency
Mounting method (vibration-dampening grommets reduce noise)
System impedance (restricted airflow increases turbulence)
For noise-sensitive environments such as medical labs or office IT rooms, we offer low-noise variants with optimized blade geometry.
What bearing types are used, and what is the expected lifespan?
All our 120mm AC fans utilize dual ball bearings. Benefits include:
Higher temperature tolerance (up to 80°C operating)
Longer service life: 60,000 hours MTBF at 40°C (L10 life)
Suitable for any mounting orientation
Superior performance in high-vibration environments
Sleeve bearings are not offered for industrial-grade products due to shorter lifespan and orientation limitations.
What safety certifications do these fans carry?
Our 120mm AC fan series are fully certified with:
UL 507 / cUL (USA and Canada)
CE (EU conformity)
TUV (Germany)
RoHS (Restriction of Hazardous Substances)
REACH (EU chemical regulation)
Certification documentation is available upon request for compliance and auditing purposes.
Do you offer private labeling or custom packaging?
Yes. We support OEM services including:
Custom brand labeling on fan housing
Custom packaging and retail-ready boxes
Modified lead wire length and connector types (e.g., Molex, JST, terminal blocks)
Special coatings (conformal coating for humid or corrosive environments)
All customizations are subject to engineering review and applicable MOQ.
