Air curtain, an invisible door

Air curtain, air door, fly fan... call it what you will, this ingenious technology is an invisible barrier of air that safeguards your indoor environment.

Whether it’s a retail store, warehouse, cold storage facility, or industrial building, air curtains offer a versatile solution for creating a more comfortable, energy-efficient, and hygienic space.

How does an air curtain work?

An air curtain acts like an invisible door. It blows a powerful, targeted stream of air across a doorway or opening, effectively separating the indoor and outdoor climates. This air barrier prevents cold or hot air from entering, while also blocking insects, dust, and other unwanted particles.

Why invest in an air curtain?

The benefits of air curtains are numerous and significant.

  • Energy efficiency: by minimizing heat loss in the winter and cool air escape in the summer, air curtains can drastically reduce your energy bills. This is especially crucial in environments with large temperature differences, like cold storage facilities.
  • Comfort: air curtains eliminate drafts and cold spots near openings, creating a more pleasant and inviting atmosphere for customers and employees.
  • Hygiene: by keeping out insects, dust, pollen, and other pollutants, air curtains contribute to a cleaner and healthier indoor environment. This is particularly important for food service establishments and healthcare facilities.
  • Rapid return on investment: a properly installed air curtain delivers a fast return on investment.

Different types of air curtains for different needs

There’s an air curtain for every application.

  • Overhead air curtains: mounted above the doorway, these are perfect for entrances with limited space on the sides.
  • Side-mounted air curtains: ideal for narrower openings.
  • Recessed air curtains: discretely integrated into the building’s structure for a seamless look.
  • Heated air curtains (electric or water-Heated): provide additional warmth at the openings during colder months.
  • Ambient air curtains (unheated): the most energy-efficient option, ideal for keeping out insects and dust.

Choosing the right air curtain for your needs

Selecting the right air curtain depends on several factors.

  • Doorway size: the air curtain must be powerful enough to cover the entire opening.
  • Temperature difference: the greater the temperature difference between the indoor and outdoor environments, the more powerful the air curtain needs to be.
  • Application: different environments have different requirements. A retail entrance needs a different type of air curtain than a cold storage facility.
  • Installation options: consider whether you have space for an overhead, side-mounted, or recessed model.
