Air Curtains

From Sonniger

Do you know what an air curtain is?

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.

How do they work?

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.

Is an air curtain effective for our store?

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.

What are the advantages of an air curtain for our business?

  • Hygienic Atmosphere
    Helps maintain a clean, healthy indoor environment.

  • Pest and Insect Control
    Prevents flies, mosquitoes and other insects from entering.

  • Filtration of Airborne Contaminants
    Blocks dust, gaseous pollutants and external odors.

  • 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.

  • Ensures unimpeded emergency egress during fires or other crises.

  • Can serve as a smoke barrier in specialized fire-protection applications.

 

For all these benefits, choosing the right air curtain is absolutely essential—leave that to Sonniger!

  • Ventilation zone: Clean air passes through ventilation openings into every room without noise.
  • Overflow zone: Clean air is distributed evenly by passing through door grille into adjoining rooms. 
  • Extraction zone: Stale, unrenewed air is expelled outside—e.g. via kitchen hood.

Fans

• Modern design
•Economical operation
• Easy to install and maintain

Clean air is essential in any home. In rooms prone to moisture—such as bathrooms and WCs—regular ventilation is vital: it not only supplies fresh air but also protects your home’s structure.

High humidity often follows a shower. Moisture settles on cold walls, leading to mold growth. That’s why a reliable ventilation and exhaust system is especially critical in interior bathrooms without windows. Controlled ventilation saves precious energy while ensuring consistent air exchange. Marley’s Menv 180 and Menv 180 Plus series deliver exactly the right ventilation every home needs.

Save energy and money while breathing clean indoor air, free of unpleasant odors and health-threatening microorganisms such as mold and moisture, by choosing Marley ventilation systems. Marley operates production plants in Germany and Hungary and is a member of global ALIAXIS group.
