How to Select Cooling Fans for Plant Cultivation Equipment? Why Are More Agricultural Environmental Control Systems Adopting IP68 Splash Proof Fans?

As modern controlled-environment agriculture continues to expand, plant cultivation equipment and plant factory systems are being widely used in vertical farming, seedling cultivation, leafy vegetable production, medicinal plant cultivation, and other high-value agricultural applications.

Unlike traditional farming, plant factories rely on precisely controlled environmental conditions to achieve stable, year-round production. As a result, temperature, humidity, airflow circulation, and CO₂ management have become critical elements of system design.

Among these environmental control components, one often-overlooked yet essential device is gaining increasing attention from equipment manufacturers: the IP68 Splash Proof Fan.

Challenges Faced by Cooling Fans in Plant Cultivation Equipment

Plant cultivation facilities typically operate under the following conditions:

These harsh environmental conditions present significant challenges for conventional cooling fans.

Engineers frequently encounter issues such as:

✔ Bearing corrosion

✔ Moisture ingress into electronic circuits

✔ Insulation degradation of motor windings

✔ Water droplets entering the fan assembly

✔ Reduced airflow performance

✔ Premature fan failure

Therefore, dustproof and waterproof performance has become a key consideration when selecting fans for plant cultivation equipment.

Why Are Standard Cooling Fans Unsuitable for Plant Factory Applications?

Most standard industrial cooling fans are designed for relatively dry indoor environments.

However, plant cultivation systems often contain:

• High humidity levels
• Water mist and spray systems
• Nutrient solution evaporation
• Condensation formation
• Continuous operation throughout the year

When moisture penetrates the fan motor or electronic components, it can lead to:

• Electrical short circuits
• Insulation deterioration
• Bearing failure
• Unstable fan speed
• Reduced reliability

Ultimately, these issues can compromise the stability of the entire environmental control system.

What Is a Splash Proof Fan?

A Splash Proof Fan is a cooling fan specifically designed to operate reliably in environments exposed to water, humidity, condensation, and dust.

According to IEC 60529, protection levels are classified using the IP (Ingress Protection) rating system.

Common IP Ratings

For plant cultivation equipment, IP68 protection has become an increasingly preferred specification.

Why Are More Plant Cultivation Systems Choosing IP68 Splash Proof Fans?

1. Reliable Operation in High-Humidity Environments

Plant factories maintain elevated humidity levels throughout the cultivation process.

Conventional fans often experience accelerated degradation under these conditions.

IP68 Splash Proof Fans provide significantly greater reliability and durability.

2. Resistance to Water Mist and Condensation

Many cultivation systems utilize:

• Humidification equipment
• Misting systems
• Nutrient solution circulation systems

These applications continuously generate moisture and water droplets.

Splash Proof Fans help minimize the risk of moisture-related failures.

3. Lower Maintenance Costs

Most plant factories operate around the clock.

Unexpected downtime can negatively affect crop production and operational efficiency.

Using highly reliable fans can help reduce:

• Maintenance frequency
• Spare parts inventory
• Service labor costs

4. Improved System Stability

Fan failures may result in:

• LED grow light overheating
• Controller temperature increases
• Air circulation disruption
• Fluctuating temperature and humidity levels

These issues can directly affect crop quality and yield.

As a result, many equipment manufacturers now prioritize Splash Proof Fans during the initial design stage.

Why Is PWM Speed Control Becoming Increasingly Important?

In addition to waterproof performance, fan speed control is another important requirement for modern plant cultivation systems.

Limitations of Voltage-Based Speed Control

Traditional voltage control methods often suffer from:

• Limited speed adjustment range
• Poor low-speed stability
• Reduced control precision

Advantages of PWM Control

PWM-controlled fans are particularly suitable for:

• Temperature and humidity control systems
• CO₂ management systems
• Air circulation systems
• Seedling cultivation equipment

Why Does Long Service Life Matter in Plant Factories?

Plant factories are designed for continuous operation throughout the year.

Fan service life has a direct impact on equipment reliability and operating costs.

Certain San Ace Splash Proof Fan models offer an expected service life of:

Up to 180,000 Hours (L10)

Equivalent to approximately:

• 20 years of continuous operation under specified conditions

Actual service life depends on environmental conditions and operating parameters.

Nevertheless, long-life fans provide significant benefits for plant factory operators seeking to minimize maintenance requirements.
