Have you ever walked into a shopping mall, a cold storage facility or a factory. Noticed a strong stream of air coming from above the entrance. That powerful airflow is called a curtain. It plays a much bigger role than most people realize in an air curtain.

Whether it’s keeping dust out, maintaining indoor temperatures, or improving energy efficiency, curtains have become an essential solution for modern commercial and industrial facilities.
