Is a Door Air Curtain the Right Fit for Your Entrance? Here’s What You Should Know

The space above your entrance door could be doing more than just housing lights or signage.
It could be hosting a powerful tool for climate control, dust reduction, and energy savings: a door air curtain.

Whether you're running a small boutique or managing multi-location retail stores, these invisible air shields are proving their value in environments where doors stay open—but conditions need to stay controlled.

What Exactly Is a Door Air Curtain?

A door air curtain is a high-speed airflow device installed above a door frame. It pushes a controlled stream of air downwards, creating a barrier between indoor and outdoor spaces. The goal? Allowing easy access while blocking:

• Hot or cold outdoor air

• Dust and pollution

• Insects and airborne particles

• Loss of heated/cooled indoor air

Unlike mechanical doors or plastic flaps, air curtains offer a frictionless, touch-free barrier that activates only when needed.

Common Applications for Door Air Curtains

This solution is widely used in:

• Retail stores and malls: Maintain temperature while welcoming shoppers

• Supermarkets and convenience stores: Prevent insects and maintain food safety

• Cafes and bakeries: Keep indoor comfort even with high foot traffic

• Clinics and pharmacies: Create a clean airflow seal at entrances

• Office buildings: Balance HVAC performance in entry lobbies

• Loading bay entry doors: Especially in cold chain warehouses

If you have swinging doors, sliding glass doors, or manual commercial entries, Aosair has models designed for each.
