San Ace 9WP0412H6001: 12V IP68 Splash Proof Fan for Low-Power, Long-Lasting Cooling in Harsh Environments
Introduction
The San Ace 9WP0412H6001 is a compact, energy-efficient Splash Proof Axial Fan from SANYO DENKI’s San Ace 40W 9WP series, purpose-built to deliver reliable cooling in environments where water, dust, and humidity threaten standard cooling solutions. Measuring just 40×40×20mm, this 12V DC fan combines IP68 ingress protection, built-in safety features, and a long service life, making it an ideal choice for cost-sensitive industrial and outdoor applications requiring low-noise, maintenance-free operation.
Uncompromising IP68 Splash Proof Protection
At the core of the 9WP0412H6001’s design is its IP68 ingress protection rating, certified to the IEC 60529 standard. The fan’s motor coils and electronic components are fully encapsulated in a specialized resin coating, creating a hermetically sealed barrier against water, dust, and moisture.
Key protection capabilities include:
-
Complete Dust Protection: Blocks all particle intrusion that could degrade performance or cause electrical failure.
-
Water Immersion Resistance: Withstands submersion in up to 2 meters of water for 60 minutes (power off), ensuring reliable operation in rain-exposed, flood-prone, or high-humidity environments.
-
Condensation and Splash Resistance: Resists splashing water, low-pressure jets, and temperature-induced condensation, eliminating risks of short-circuit or corrosion in harsh settings.
Optimized Performance for Compact, Low-Noise Systems
Despite its small footprint, the 9WP0412H6001 delivers balanced cooling performance tailored for compact equipment and moderate airflow resistance:
-
Rated Speed: 8000 rpm
-
Maximum Airflow: 0.225 m³/min (8.0 CFM)
-
Maximum Static Pressure: 65.7 Pa (0.264 inchH₂O)
-
Sound Pressure Level: 33 dB(A) at 1m from the air inlet
This performance strikes the perfect balance between effective heat dissipation and low-noise operation, making it ideal for space-constrained systems where excessive fan noise is a concern.
Key Features for Industrial & Outdoor Reliability
The 9WP0412H6001 is packed with features designed to enhance long-term performance, safety, and system integration:
-
Ultra-Low Power Consumption: With a rated power of just 1.2W and a rated current of 0.1A, the fan minimizes energy draw, supporting efficiency goals in battery-powered or low-power industrial systems.
-
Built-In Safety Protections: Equipped with locked rotor burnout protection and reverse polarity protection, preventing damage from fan stall or incorrect wiring and ensuring safe, reliable operation.
-
Long Service Life: Boasts an expected lifespan of 40,000 hours at 60°C (70,000 hours at 40°C) under continuous indoor free-air operation, reducing maintenance needs in hard-to-access installations.
-
Pulse Sensor Monitoring: Features a built-in pulse sensor to provide real-time fan speed feedback, enabling system health monitoring and fault detection for critical equipment.
-
Ribbed Frame Design: Includes a ribbed structure for enhanced structural stability and heat dissipation.
-
Wide Operating Range: Supports a 7–13.8V DC input voltage range and a -10°C to +60°C operating temperature range, ensuring stable performance across diverse environmental conditions.
-
Global Compliance: Certified with UL standards and fully compliant with RoHS directives, making it suitable for global industrial and commercial applications.

Typical Applications
The 9WP0412H6001 is tailored for applications that require reliable, low-noise cooling in harsh environments:
-
Outdoor Digital Signage & Displays: Compact, rain-exposed equipment needs splash-proof cooling without excessive noise.
-
Refrigerated Showcases & Cold Chain Devices: Condensation-prone environments demand fans that prevent moisture ingress during maintenance.
-
Bakery & Confectionery Equipment: High-humidity, dust-prone facilities require durable, low-power cooling solutions.
-
Plant Cultivation & Factory Automation: High-humidity growing environments and industrial facilities need long-lasting, energy-efficient fans.
-
Solar Inverters & Low-Power Industrial Systems: Outdoor installations require robust, low-noise cooling with IP68 protection.
Important Usage Notes
-
The IP68 rating applies only to live electrical components (motor coils and electronic parts). Mechanical components such as impellers and bearings are not covered by this rating.
-
Do not wash the fan directly during maintenance, as this may cause damage or malfunction to mechanical parts.
-
For extended use in environments with high condensation or extreme humidity, implement additional protective measures and evaluate performance under specific operating conditions.
Conclusion
The San Ace 9WP0412H6001 is a versatile, reliable splash-proof fan that delivers balanced performance, ultra-low power consumption, and IP68 protection in a compact 12V form factor. Backed by SANYO DENKI’s legacy of quality engineering, it is the ideal choice for engineers designing cost-effective, low-noise cooling solutions for harsh, moisture-prone environments.
