Poultry Exhaust Fan A poultry exhaust fan is a type of ventilation fan specifically designed for use in poultry farms or chicken coops. These fans are crucial for maintaining a healthy environment for the birds by removing excess heat, moisture, and airborne contaminants such as dust, dander, and ammonia fumes. Poultry exhaust fans are typically large and powerful, capable of moving a high volume of air to ensure proper ventilation within the facility. They may be installed in the walls or ceilings of the poultry house, strategically placed to effectively remove stale air and circulate fresh air throughout the space.
