Article 7: Axial Fans in Agricultural Greenhouses Axial fans enhance greenhouse environments by regulating temperature, humidity, and CO2 levels for optimal plant growth. They provide cost-effective ventilation in controlled agriculture. In vegetable greenhouses, axial fans exhaust hot air through roof vents, drawing in cooler outside air. A 36-inch fan can circulate 10,000 CFM, preventing heat stress in crops like tomatoes. Hydroponic systems use axial fans for air mixing, ensuring even nutrient distribution. Variable-speed models respond to sensors, maintaining 70-80°F ideals. In floriculture, fans reduce humidity to curb fungal diseases. Pad-and-fan evaporative cooling pairs with axial ac fans for arid regions. Livestock barns employ axial fans for odor control and ac axail heat relief. In poultry houses, they improve air quality, boosting feed efficiency.
