Not more than 8″ for refrigeration and 14″ for insects. To seal off the ends, 12″ to 18″ panels made of sheet metal, plastic strips, or plywood can be installed on each side of the door opening to improve the efficiency of the air curtain. Sometimes the Mars Air Curtain outlet nozzle may be installed between the obstruction and the wall. Precaution is necessary to prevent the obstruction from deflecting the flow of air.
