Air Curtain Technology:
Energy Efficiency & Indoor Comfort
Discover how air curtains create a barrier that saves energy, improves comfort, and enhances productivity in commercial and industrial spaces.
What is an Air Curtain?
An air curtain is a powerful stream of air that creates an invisible barrier across doorways and openings, separating two different environments while maintaining visibility and accessibility.
How Air Curtains Work
Air curtains work on a simple principle: a high-velocity jet of air is emitted from a blower unit installed above a doorway, creating an air barrier that separates two spaces. This barrier effectively reduces the transfer of air, dust, insects, and contaminants between indoor and outdoor environments.
By maintaining a consistent airflow, air curtains help to keep conditioned air inside during heating or cooling seasons, resulting in significant energy savings and improved comfort for occupants.
Key Principle
The effectiveness of an air curtain depends on factors such as airflow velocity, throw distance, and the height and width of the opening. Proper installation and sizing are critical for optimal performance.
Horizontal Airflow
Most common type for doorways
Vertical Airflow
Ideal for large openings
Energy Savings
Reduce heating and cooling costs by up to 30% with proper air curtain installation.
Applications of Air Curtains
Air curtains are versatile solutions used in a wide range of industries and settings to improve comfort, energy efficiency, and operational performance.

Benefits of Air Curtains
Installing an air curtain offers numerous advantages for businesses and facilities of all types, from energy savings to improved indoor comfort.
Energy Efficiency
Air curtains reduce the loss of conditioned air, lowering heating and cooling costs by up to 30%. This makes them a cost-effective solution for businesses looking to reduce energy consumption.
Improved Air Quality
By creating a barrier, air curtains prevent the entry of dust, pollen, exhaust fumes, and other outdoor pollutants, leading to cleaner and healthier indoor air.
Insect & Pest Control
Air curtains act as a barrier to keep insects and pests out of commercial spaces, eliminating the need for chemical pesticides and improving hygiene.
Enhanced Comfort
Maintaining consistent indoor temperatures creates a more comfortable environment for employees and customers, leading to increased productivity and satisfaction.
Compliance with Regulations
Air curtains help businesses meet health and safety regulations by preventing cross-contamination and maintaining proper temperature control in food service and healthcare settings.
Cost Savings
Lower energy bills, reduced maintenance costs for HVAC systems, and improved product preservation result in significant long-term savings.

Types of Air Curtains
Air curtains come in various types and configurations to suit different applications and environments.
Standard Air Curtains
Designed for general-purpose use in commercial and industrial settings, standard air curtains provide effective air separation for doorways up to 3 meters in height.
- Suitable for most standard doorways
- Energy-efficient operation
- Quiet performance
High-Velocity Air Curtains
Ideal for large openings, industrial environments, and areas with high traffic, high-velocity air curtains create a powerful barrier to separate environments with significant temperature differences.
- Powerful airflow for large openings
- Handles extreme temperature differentials
- Durable construction for industrial use
Heated Air Curtains
Combining air barrier functionality with heating capabilities, these units are perfect for cold climates, keeping warm air inside while still maintaining an open doorway.
- Efficient heating and air separation
- Reduces cold drafts in winter
- Available in electric or gas models
Comparison of Air Curtain Types
| Feature | Standard Air Curtains | High-Velocity Air Curtains | Heated Air Curtains |
|---|---|---|---|
| Ideal Door Height | Up to 3 meters | 3-6 meters | Up to 4 meters |
| Airflow Velocity | Medium | High | Medium to High |
| Temperature Control | No | No | Yes (heating function) |
| Energy Efficiency | High | Moderate | High (with heating) |
| Typical Applications | Retail stores, offices, restaurants | Warehouses, loading docks, industrial facilities | Cold climates, entryways in winter |
| Noise Level | Low to Moderate | Moderate to High | Low to Moderate |
| Cost | Low to Moderate | Moderate to High | Moderate to High |
How to Select the Right Air Curtain
Choosing the appropriate air curtain for your needs requires considering several factors to ensure optimal performance and energy efficiency.
Key Selection Factors
Door Size and Height
The dimensions of the doorway are critical. Measure the height and width accurately, as air curtains are sized to match specific door dimensions. For doors taller than 3 meters, high-velocity models are recommended.
Temperature Differential
Consider the difference between indoor and outdoor temperatures. Larger differentials require more powerful air curtains. In cold climates, heated air curtains can provide additional comfort and energy savings.
Traffic Volume
High-traffic areas like retail stores or loading docks need air curtains with robust motors and durable construction. Consider models designed for continuous operation in such environments.
Airflow Velocity and Throw
The required airflow velocity depends on the doorway height and environmental conditions. Higher velocities are needed for larger openings or areas with strong drafts.
Energy Efficiency
Look for energy-efficient models with features like variable speed controls and thermal insulation. These can significantly reduce operating costs over time.
Installation Environment
Consider the installation location. Wet or corrosive environments (like food processing facilities) require stainless steel or waterproof models. Ceiling or wall-mounted options should be chosen based on available space.

Air Curtain Installation Guide
Proper installation is crucial for the effectiveness and longevity of your air curtain. Follow these guidelines for optimal results.
Installation Process
Prepare the Installation Area
Ensure the mounting surface (ceiling or wall) is structurally sound and can support the weight of the air curtain. Clean the area of any debris or obstructions.
Position the Air Curtain
Place the unit directly above the doorway, ensuring it is centered and level. The bottom of the air curtain should be installed at the recommended height (typically 2.1-2.4 meters for standard units).
Mark and Drill Mounting Holes
Using the unit as a template, mark the positions for the mounting holes. Drill holes into the surface and insert appropriate anchors for the wall or ceiling material.
Mount the Unit
Lift the air curtain into place and secure it using the provided bolts or screws. Ensure the unit is firmly attached and does not wobble.
Electrical Connection
Connect the air curtain to a suitable power supply according to the manufacturer's instructions. For heated models, ensure the electrical circuit can handle the additional load.
Test the System
Power on the air curtain and check the airflow pattern. Adjust the angle if necessary to ensure the air stream covers the entire doorway. Test any additional features such as heating or variable speed controls.
