About Us

JanAire all began in 1987 when I started wondering if a “PolyVent”, (that is what we call our air operated curtains) could replace conventional curtains and doors on livestock buildings.

We installed our first two “PolyVent” and “RidgeVent” systems on hog finishing units in Minnesota in the fall of 1987. That winter, the temperature got down to MINUS 35 degrees – three times!
That following spring, we had 2 happy customers!!! Our first naturally ventilated hog buildings!

We took what we had learned from our first winter and made a few basic changes to the frames, and, coming from a dairy and hog background, we HAD to try our JanAire Curtain in a dairy.

Next, we tried a dairy free stall, a calf barn, more hog barns, and then, a turkey finisher the year of 1988. That winter was a normal, cold and snowy winter; and, by spring, JanAire had seven happy customers!

Since then, we have installed thousands and thousands of JanAire Air Curtain Systems in North America, Canada, Russia, and Europe.

Our JanAire Customers keep giving us new challenges like:

Would your air curtain system work to keep sand out of my parlor during a sand storm? (it does!)

I need a “Fail Safe” on my power ventilated barn in case the controls malfunction, would yours work? (it does!)

Our customers are what make JanAire interesting – they keep us going!

Four special reasons why dairy producers like JanAire Inflatable Agricultural Curtains

  1. The Light
    “It’s so much easier to observe the cows – everyone enjoys working in a bright atmosphere.”
  2. Quiet
    “Our original conventional curtains used to whip and flap in the wind. It would really get on your nerves after awhile. Now, with JanAire PolyVent on our free stall, it’s peaceful, quiet, and the dairy cattle are not distracted by irritating noises.”
  3. Automatic
    “Especially during spring and fall, the weather swings a lot in our area, way too much to try and keep up with a manual system. With JanAire, I just set the thermostats and forget about it. I’ve got other things to do!” (The top half of a stacked JanAire unit is generally operated with a thermostat, the bottom half is controlled with an on/off switch).
  4. Insulated, Seals Tight
    “Parlors and holding areas are very active areas. When they are filled with cattle, they require large openings to allow for a lot of air movement. Yet when they are empty, they need to close up tight to keep the area from freezing in cold weather.”

Don’t forget to complete your holding areas and special needs barns with a JanAire RidgeVent!

Also, be sure to plan for an eave opening on your free stall or calf barn. The size of the opening depends on how severe your winter weather is.

A calf barn might get by with a vented soffit, or a ½” crack at the top of the wall.

A free stall might work great with a 2” opening for air. If you realize a 2” opening is too much, you can always shrink it down to a 1” opening.

But, if you build your building with a 1” opening and wish it was more, you’ll have a much bigger job opening it back up. Often times, we see where a builder will leave, for example, a 6” opening at the top of the wall. The dairy owner will say that it is too much opening, and then closes it up tight, or, the builder builds it too tight and the dairy owner says to open it wide open. Somewhere in between would be just right.
