The only exhaust fan specifically designed for cold weather /snow/high winds in the industry.

This fan is made in Montana by our friend Jerry at Bear Country Containers. It is perfect for greenhouses and also designed for utility rooms, warehouses and factories.

Wall mounted it is easy to install and moves 2,000 Cubic feet of air per minute!

What To Expect When THE Project Begins

Jerry Kawasaki

As the owner of Backcountry Aluminum Paniers Jerry Kawasaki worked with the US Forest Service to create alumimum horsedrawn storage boxes that are bear-proof in the backcountry. Jerry’s skill and design knowledge about bending and welding aluminum helped tremendously in designing our custom exhaust fans. Jerry makes each of the Alpine fans by hand in his shop in Gallatin Gateway Montana and lightens up the world with his smile and his cowboy tales!
