From Sonniger

An air curtain is a device equipped with a fan that creates an invisible barrier of air above a doorway to effectively separate two different environments without restricting people’s access.

Air drawn in through the intake is pressurized by internal fans and expelled through the discharge outlet, forming an air jet directed toward the open doorway below. This invisible barrier protects your building or store from dust, insects, and some air particulates that might enter your space.

Heated air curtains incorporate a heating element—whether electric, hot/cold water, steam, or similar—to condition the discharged air. This prevents occupants from feeling a draft of cold air as they pass through the doorway and also warms the volume of incoming air, enhancing overall comfort and energy efficiency.

Absolutely!

Every study and test has demonstrated that air curtains are highly effective in a retail environment. By selecting the appropriate air curtain and installing it correctly, you not only achieve significant energy savings but also ensure that your building’s entrances remain protected from external conditions and free of insects, odors, and other unwanted particulates.

• Increased Foot Traffic & Sales
  The “open-door effect” attracts more passers-by into your store, boosting revenue.

• Enhanced Store Visibility
  An unobstructed entrance acts like a window, inviting customers to look inside.

• Unhindered Accessibility
  Enables easy access for people with mobility aids, strollers or wheelchairs.

• Optimized Entrance Space
  Frees up usable floor area at doorways by eliminating the need for physical barriers.

• Improved Comfort for Customers & Staff
  Eliminates drafts and temperature fluctuations at the entrance.

• Energy Savings
  Reduces thermal losses from heated or cooled zones, lowering HVAC load (kW) and operating costs.

• Enhanced Safety

• Minimizes condensation and ice buildup in cold environments.
