The SFS is an air curtain with many clever functions, specially designed for revolving doors. The air curtain is mounted vertically and its curved design integrates neatly with the door. SFS efficiently protects the exposed area just above the floor.
A revolving door prevents continuous drafts but still lets in a certain amount of cold air at every rotation. The air curtain prevents the cold air from penetrating and gives good heating comfort.

The SFS has a curved design that follows the shape of the revolving door and is available in powder-coat painted or stainless steel. The product key offers many options for the design and finish of the air curtain.
