Positive pressure tubes installed to supplement natural ventilation in the milking center holding area and aid in heat abatement.
Airjets are targeted to reach 300-400 ft/min (1.5-2 m/sec) at the level of the cows’ backs, in effect “showering” cows with fresh air at minimum heat abatement speed when combined with soaking from sprinklers.
All combined, the 6 positive pressure tube systems deliver fresh air at a rate of approximately 50 air changes an hour.
