Do air curtains really work?

Air curtains, a.k.a. air doors or fly fans, properly selected, installed and operated really do work to create a barrier out of air across an opening. So much so, that ASHRAE Standard 90.1-2019 and the International Energy Conservation Code (IECC) building code allows AMCA certified air curtains as an alternative to vestibules.

Are air curtains effective?

Energy Conservation & Comfort: Research shows that properly selected, installed and operated air curtains are +/- 80% effective at keeping warm air on one side and cold air on the other when the door is open.

Flying Insect Control: Research with the USDA shows that air curtains are effective at preventing flying insects from passing through the air stream formed across the opening.

How do air curtains work?

When the door is open, Berner air curtains form a barrier out of air that:

• Keeps warm air on one side and cold air on the other
• Keeps flying insects out, chemical-free
• Keeps out fumes such as cigarette smoke, carbon monoxide, and odors
• Allows people, machines and goods to enter and exit
