pig barn ventilation

Mechanical ventilation by exhaust fan is the most popular form of ventilation for pig barns, and is more technologically advanced, it is also most cost-saving and energy-efficient.

Ventilation fans form a static negative pressure inside the pig barn, which are typically inlets the fresh air from outside, and extract the contaminated air out through fans.

The mechanical fan ventilation system inside the pig barn affects air temperature, moisture level, surface moisture concentration, air temperature uniformity, air speed across pigs, and airborne dust and gases generated by pigs, which can affect the health performance of the pigs.
