Types of Commercial Air Curtains

A basic air door provides an untempered stream of air to protect an opening. This works very well, but in colder climates, an commercial overhead door heater can offer the benefit of supplemental heat.

When used as supplemental heating, an air curtain is a powerful heater and air recirculation tool that reduces the central HVAC system load.

Several methods of tempering air are available, which include:

Heated Air Curtains that Enhance HVAC Efficiency:

Heated air curtains offer numerous advantages for various applications.

Energy Savings:

  • Forming a warm air barrier, heated air curtains prevent the escape of warm air and the intrusion of cold air, resulting in energy savings.

Indoor Air Quality:

  • They act as a barrier against pollutants, making them ideal for hospitals, labs, and restaurants where clean air is crucial.

Comfort and Safety:

  • Even temperature distribution enhances occupant comfort, especially in places with significant temperature variations.
  • Keeps floors dry, contributing to both customer and staff safety.


  • Suitable for a range of applications, heated air curtains offer benefits such as improved safety, and energy efficiency.

Types of Heated Air Curtains

Electric Heated Air Curtains:

  • Warm the air with electric heating elements.
  • Convenient and easy to install, suitable for various applications.

Hot Water Heated Air Curtains:

  • Utilize hot water to warm the air.
  • Generally, lower energy consumption compared to electric options, requiring a water source and plumbing system.

Steam Heated Air Curtains:

  • Use steam for heating, often in industrial settings.
  • Installation and maintenance can be more complex.

Indirect Gas-Fired Air Curtains:

  • Employ a heat exchanger for consistent, even heating.

There are plenty of additional benefits to commercial air curtains.

Additional benefits of air curtains for commercial applications are:


  • Maintains temperature
  • Prevents bugs & pests from entering
  • Significantly reduces fumes, dust, and odors from entering
  • AMCA certified
  • Meets ASHRAE Standard 90.1-2019
  • Filter is washable
  • Virus elimination

Air curtains with media filters and sanitizers clean indoor air using filters and UV light. This reduces indoor pollutants while simultaneously preventing bugs and pollutants from entering.

They create an invisible barrier over an entrance door that keeps dust, bad smells, and pollution from getting to customers and staff.

Energy Efficient

  • Reduces the HVAC load
  • Decreases energy expenses
  • CO2 emissions are reduced

Commercial air curtains pay for themselves in energy savings, and in some cases in less than a year (source). The air curtain will pay for itself by stopping leaks at their source and reducing the amount of energy the HVAC system needs to use.

A secondary benefit, but no less important, is the reduction in carbon footprint. Air curtains facilitate a significant reduction in the energy used by the HVAC system.

This change in operation directly leads to less energy use and less CO2 being released into the environment.

The result is a greener approach to HVAC that has been proven and offers potential LEED credits for new construction.

Improves Safety

  • Keeps floors dry
  • Prevents fires from spreading
  • Easier evacuation in case of an emergency


In case of an emergency, such as a fire, the air curtain acts as a barrier between 2 areas. This limits or at least slows the progression of a fire. Since the air curtains are over entrance doors, people are able to evacuate without obstruction.
