Devices used in outdoor or factory environments are often exposed to water, dust, and other harsh conditions. The fans integrated into these devices must also meet strict waterproof and dustproof standards to ensure reliable operation.
This article provides a detailed overview of how Splash Proof Fans work, their key features, and IP (Ingress Protection) ratings , along with case studies.
1. What is a Splash Proof Fan?
We will explain how Splash Proof Fan works.
These fans are designed with waterproof features that allow them to operate safely in environments where they may be exposed to water.
The motor and circuit board are coated with resin, creating a sealed structure that prevents water and dust from entering the live electrical components.
2. What is the Protection Rating (IP Code)?
The protection rating (IP code) that indicates waterproof performance is a rating from 0 to 6 for protection against intrusion of foreign objects into electrical components inside a device (in the case of a fan, electronic components and motor coils), and a rating from 0 to 8 for protection against intrusion of water. For example, in the case of IP65, protection against intrusion of foreign objects is "6, dustproof," and protection against intrusion of water is "5, protected against jets."
The required protection rating varies depending on the operating environment. Generally, ratings such as IP55, IP65, IP67, and IP68 are widely used. Our Splash Proof Fans provide protection ratings from IP54 to IP68.
*Protection ratings (IP codes) are specified in IEC (International Electrotechnical Commission) 60529.
3. Case Studies on the Use of Splash Proof Fans
Here are several case studies illustrating the implementation of Splash Proof Fans in actual devices and systems.
(1) EV Chargers
• Due to outdoor installation, it is critical to ensure a high level of durability and reliability.
• To support environmental sustainability, lower power consumption is also required.
Solution with Splash Proof Fans
• Implementing Splash Proof Fans provides a reliable solution for improving durability and operational stability.
• A 70%* reduction in fan power consumption helps enhance the energy efficiency of the overall system.
• A fourfold* increase in fan life expectancy contributes to lower maintenance requirements and improved operational efficiency.
*Based on the fan used in this specific case study.
(2) Digital Signage
• The current axial fans do not provide sufficient cooling performance for thinner equipment designs.
• Outdoor installation requires waterproofing that accounts for exposure to rain and other weather conditions.
Solution with Splash Proof Centrifugal Fans
• The use of Splash Proof Centrifugal Fans enables effective cooling performance in compact installation environments.
• With an IP54 protection rating, the fan meets waterproofing requirements and helps resolve related challenges.
(3) Bakery and Confectionery Equipment
• The fermentation system environment involves significant dust dispersion, leading to the evaluation of fans equipped with dust-resistant features.
• Controlling fan speed through input voltage results in a limited adjustment range.
Solution with Splash Proof Fans
• Rated IP68, the fan is capable of operating reliably in high-humidity environments with significant dust dispersion.
• PWM control enables more flexible and precise speed adjustment than voltage-based control.
(4) Refrigerated Showcases
• During maintenance, melted frost may result in water droplets entering the fan.
• It is necessary to reduce power consumption.
Solution with Splash Proof DC Fans
• The use of Splash Proof Fans prevents water ingress.
• Switching from AC fans to DC fans enables lower power consumption.
(5) Plant Cultivation Equipment
• Airflow management is required in environments where there is a risk of water exposure.
• Reducing total energy costs across the entire plant cultivation facility is a key objective.
Solution with Long Life Splash Proof Fans
• Implemented waterproof connectors through a customized design to ensure protection against moisture and harsh conditions.
• To address energy efficiency needs, a Splash Proof ACDC Fan with low power consumption was proposed.
Apart from the cases mentioned above, Splash Proof Fans have been widely adopted in many applications.
