San Ace 9WPA0412P6G001: The Ultimate IP68 Splash Proof Fan for Harsh Environment Cooling
Introduction
The San Ace 9WPA0412P6G001 is a compact, high-performance Splash Proof Axial Fan engineered by SANYO DENKI, designed to deliver reliable cooling in environments where water, dust, and moisture pose constant threats to electronic systems. Built on the trusted San Ace 40W platform, this 40×40×20mm fan combines IP68-rated protection, industry-leading airflow performance, and intelligent control features to meet the most demanding cooling requirements of outdoor and industrial applications.
Uncompromising IP68 Splash Proof Protection
At the core of the 9WPA0412P6G001 is its IP68 ingress protection rating, fully compliant with the IEC 60529 standard. The fan’s motor and circuit board are coated with a specialized resin, creating a hermetically sealed structure that prevents water, dust, and humidity from reaching critical electrical components. This enables the fan to withstand submersion in 2 meters of water for up to 60 minutes (power off), making it ideal for use in rain-exposed, splash-prone, or high-humidity environments.
Key protection features include:
-
Complete dust-tight enclosure, eliminating particle intrusion that could cause performance degradation or failure
-
Resistance to splashing water, low-pressure jets, and temporary submersion
-
Protection against condensation in temperature-fluctuating environments
High-Performance Cooling for Demanding Systems
Despite its compact 40×40×20mm form factor, the 9WPA0412P6G001 delivers exceptional cooling power, optimized for systems with high airflow resistance:
-
Rated Speed: 13700 rpm
-
Maximum Airflow: 0.38 m³/min (13.4 CFM)
-
Maximum Static Pressure: 210 Pa (0.84 inchH₂O)
-
Sound Pressure Level: 44 dB(A)
This performance ensures effective heat dissipation even in enclosed or densely packed equipment, preventing overheating in critical applications like EV chargers and outdoor digital signage.
Intelligent Control & Reliability
The 9WPA0412P6G001 is equipped with advanced features to enhance system efficiency and reliability:
-
PWM Control Function: Allows precise, dynamic speed adjustment based on system temperature. This reduces power consumption, lowers noise levels during low-load operation, and extends the fan’s service life.
-
Pulse Sensor: Provides real-time fan speed feedback, enabling system health monitoring and fault detection for mission-critical equipment.
-
Long Service Life: Boasts an expected lifespan of 40,000 hours at 60°C (70,000 hours at 40°C) under continuous operation, minimizing maintenance requirements in hard-to-access installations.
-
Wide Operating Range: Supports a 10.8–13.2V DC input voltage range and a -20°C to +70°C operating temperature range, ensuring stable performance across diverse environmental conditions.

Typical Applications
The 9WPA0412P6G001 is designed for applications where reliability in harsh conditions is non-negotiable:
-
EV Charging Stations & Battery Storage: Outdoor installations require robust protection against rain, dust, and temperature fluctuations, combined with energy-efficient cooling.
-
Outdoor Digital Signage & Displays: Thin, compact equipment needs high-performance cooling in rain-exposed environments.
-
Bakery & Confectionery Equipment: High-humidity, dust-prone environments demand splash-proof fans with flexible speed control for precise fermentation management.
-
Refrigerated Showcases & Cold Chain Devices: Condensation and water exposure during maintenance require fans that prevent moisture ingress.
-
Plant Cultivation & Factory Automation: High-humidity growing environments and industrial facilities need long-lasting, low-power cooling solutions.
-
Solar Inverters & Industrial Control Systems: Outdoor and harsh industrial settings require reliable cooling with protection against the elements.
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 9WPA0412P6G001 sets a new standard for compact, high-performance cooling in harsh environments. Combining IP68 splash proof protection, industry-leading airflow performance, intelligent PWM control, and long-lasting reliability, it is the ideal choice for engineers designing outdoor, industrial, or moisture-prone electronic systems. Backed by SANYO DENKI’s legacy of quality and innovation, this fan ensures consistent, efficient cooling even in the most challenging conditions.
