The 4 Seasons side air inlet is characterized by a fixed hinge point. The body is made of high quality formply and the vent is well insulated and has absolutely no cracks. This makes the 4 Seasons side air inlet a very solid, simple and reliable side air inlet that has been proving its worth for 20 years.
The vent of the 4 Seasons side air inlet opens at the top first and sends the air straight into the barn. When the upper part of the vent is open 10 – 15%, the lower part will also open. This deflects the incoming air downward, creating a gentle rolling effect and optimally directing the air to the right part of the barn.
All 4 Seasons side air inlets have a formply body and are available in any size. The opening in the wall should be 6 mm larger than the formply body. For concrete barns, we make custom-made embedded frames.
