Industrial and Commercial Air Curtains for Efficient Climate Control

Keep Comfort In, Keep Contaminants Out with Air Curtains

With Environmental Air Technology’s industrial air curtains, you can keep your workspace comfortable without sacrificing convenience. These systems create an invisible stream of air across open doorways, helping you block out dust, odors, and outdoor temperatures. They work without slowing down foot traffic or blocking your view, making them a seamless addition to any entry point in your facility.

You’ll maintain better control over your indoor climate, which means lower energy bills and a more pleasant environment for everyone inside. Whether you’re managing a busy warehouse or a customer-facing storefront, an air curtain lets you focus on your operations while quietly supporting your comfort and efficiency.

What is an Air Curtain?

Air curtains, also known as air doors, create a steady stream of air across open doorways to form an invisible barrier. This airflow helps maintain indoor temperatures by keeping warm or cool air inside while blocking outside air from entering. As a result, businesses can reduce energy costs and keep indoor spaces more comfortable for both employees and customers.

In addition to temperature control, air curtains help prevent dust, fumes, and flying insects from entering the building. They are commonly used in places like warehouses, grocery stores, hospitals, and restaurants where it’s important to maintain a clean and controlled environment without slowing down foot traffic or blocking visibility.


How an Air Curtain Works

  1. Air is Pulled In: The unit draws in surrounding air through the intake.
  2. Fan Speeds Up the Flow: A fan pushes the air forward at high speed.
  3. Plenum Spreads the Air: The air enters a plenum that distributes it evenly.
  4. Vanes Direct the Stream: Shaped vanes create a smooth, focused airflow.
  5. Barrier is Formed: The air flows downward to the floor, with 80% recirculated and 20% deflected outward to block contaminants.

Why Use An Air Curtain?

  • Unhindered traffic flow
  • Reduce flying insect infiltration
  • Maintain usable space around door
  • Maintain employee/customer comfort
  • Unobstructed visibility across threshold
  • Energy savings through control of air transfer
  • Elimination of ice and fog in cold storage areas
  • Increased productivity due to stable temperatures
  • Energy savings thanks to shorter run times of air handler or compressor
