How Do Air Curtains Work?

Air curtains deliver consistent flow of air across the width of an opening.  That flow of air results in a barrier between two distinct environments. Ineffective plastic strips are commonly used due to their initial cost. However, air curtains are more energy-efficient, sanitary, and highly effective in retaining cooler and freezer temperatures.  Air curtains also eliminate the need to constantly replace shredding, ripped and dirty plastic strips making them more attractive and cost effective long-term.  Applications range from retail to restaurant, industrial spaces, warehouses, large entertainment venues, cooler and freezer walk-in storage, drive-thru windows, transportation terminals, healthcare and hospital settings, cleanrooms, electronics manufacturing and a variety of specialty applications where water, condensation, harsh climatic conditions or unique circumstances benefit from an unobstructed stream of air.
