When selecting an air curtain for Customer Entryways or Main Entryways, it is important to know the height of the opening to determine the right amount of air velocity to effectively place an air barrier from the outside air from coming inside.

An important point is the amount of noise and air volume that customers will be subject to. There needs to be enough power to move the air and with power comes noise. The higher the door, the more power is required. The Mars LoPro(LPV2) series is the quietest model available and is good for minor temperature control. The Mars Standard(STD2) series is also good for customer entryways.
