Air transfers between the inside and outside of a building when its door is open.
By delivering a constant ow of air across an opening, an air curtain 
provides an invisible shield of air that separates environments in a 
building, whether it be climate controlled inside air from non-controlled 
outside air or internal work areas that need to be separated. It is also  
effective for inhibiting air borne contaminants, such as ying insects, 
dust, dirt, and fumes. Applications run from small pass-thru drive-up 
windows to retail stores to restaurants to larger warehouse and  
manufacturing loading dock doors.
