The JanAire Difference

There are many ventilation systems out there, but the unique features of the JanAire system make it the industry leader.


“We, at Holmacres, have had the pleasure to work with the JanAire company for the past twenty years. The curtains and the service have always been exemplary. To me the best asset has been the people that have worked with us to provide the product.”

Pam Franz, Holmacres

“We at P & J Products have been raising turkeys for over 50 years. In September 2018 a devastating series of tornadoes hit Southern Minnesota and our farm took considerable damage. After recovering and rebuilding we continued to work with JanAire Curtain’s on our barns. Not only for their quality, but also their service through such challenging times.”

John Zimmerman, P & J Products

“We installed JanAire Curtains on our dairy barn in 2010. On September 20, 2018 we lost the barn (and had significant damage to our property) due to an EF1 tornado. Tornado aside there is no doubt we could have had another 4-5 years out of those curtains. As we rebuilt, we made improvements to the barns but one thing stayed the same, our JanAire Curtains. They simply work.”

Alan Meyer, Richland Dairy
