Are there any situations that will cause an Air Curtain not to perform properly?
Yes, there are a few situations that will cause an Air Curtain not to perform as desired. The main reason is if there is an excessive negative pressure in the building. No Air Curtain can withstand excessive negative pressure. Some make up air has to be provided in these cases, in addition to an Air Curtain. The other situations arise from faulty installation of the Air Curtain. The Air Curtain will not perform properly if it is drawing outside air, or if it is not adjusted properly.
