Bockhahn, Jennifer; Gooch, Curt
In general, positive pressure air ventilation systems consist of wall-mounted fans blowing fresh outside air into the calf barn. With tube fan systems, flexible or even ridged tubes with a series of discharge holes are attached to a fan to distribute air. The fan draws fresh air in from the outside to pressurize the tube and a small amount of air exits from each hole along the length of the tube.
