Fast Fact: Air Exchanges in the Summer – Ann Hoskins, Vita Plus

Quck answer:  40 to 60 exchanges per hour

A little more on that: 

By Ann Hoskins, Vita Plus calf products coordinator
Summer and winter ventilation requirements are very different in calf facilities.  During the warm months of summer, you will want to “change out” the air 40 to 60 times per hour.  In the winter, we shoot for four air exhanges per hour.

The reason for the difference is that, in the summer, we want to provide more air movement to help the animals stay cool.  However, whether it’s winter or summer, we still don’t want to expose the calves to any drafts.

Positive pressure tubes will suffice for most barns in the winter.  In the summer, additional positive pressure tubes can be added.  In some cases, supplemental fans may be necessary.

The key is finding the right combination to achieve the ventilation goals for the season.  Of course, your winter ventilation will probably be a component of your summer ventilation.  That said, it’s not as simple as increasing the fan speed to make your winter system a summer system.

Work with a specialist trained in ventilation systems to assure your calves receive proper air flow.  Your Vita Plus team can assist in this process.
