Vent fans are used in AHP silo for several reasons:

1. Air Quality Control: Ventilation fans help control air quality inside the silo by removing dust, moisture, and other airborne particles that can accumulate and affect the quality of the stored material.
2. Moisture Control: Ventilation fans help regulate moisture levels within the silo by circulating air and preventing condensation buildup. Excess moisture can lead to material degradation, clumping, and spoilage, particularly in agricultural or food storage silos.
3. Temperature Regulation: Ventilation fans helps in maintaining consistent temperatures inside the silo by circulating air, preventing localized hot spots or temperature differentials that can affect the stored material’s quality.
4. Prevention of Silo Pressurization: During material loading or unloading operations, air can become trapped inside the silo, leading to pressurization. Vent fans help alleviate pressure buildup by providing a means for air to escape, reducing the risk of structural damage or material bridging.
5. Safety: Proper ventilation is essential for maintaining safe working conditions inside the silo, as it helps prevent the buildup of hazardous gases, such as carbon dioxide or methane, which can pose a risk to workers.
