Air Curtains for Comfort and Energy Savings

Air curtains, also known as air doors, create a high-velocity stream of air over an open doorway. This invisible barrier separates two environments without blocking the view or limiting traffic flow. By controlling the transfer of conditioned air, air curtains help maintain indoor temperature, reduce energy consumption, and protect against dust, pollutants, and flying insects.

Whether for industrial air curtains at loading docks or commercial air curtains for retail stores, these systems integrate seamlessly with modern HVAC systems.

How Does an Air Curtain Work?

An air curtain draws in air through an intake grille, accelerates it using a fan, and forces it through a narrow outlet across the opening. This creates a continuous air seal. The discharge angle and speed are optimized to prevent outside air from entering while keeping conditioned air inside.

For cold climates, a heated air curtain or air curtain heater can add warmth to improve comfort. In warm climates, ambient or electric air curtains block heat and humidity from entering.

Benefits of Air Curtains

• Reduce energy bills by minimizing heating and cooling losses
• Maintain comfort for employees and visitors
• Improve indoor air quality by blocking dust, odors, and pollution
• Prevent insect entry without chemical treatments
• Support workflow by keeping doors open for easy access
• Enhance safety by eliminating visibility barriers such as PVC strips

Studies show that air curtains can lower HVAC system run-time and, in many applications, pay for themselves within a few years.

Do Air Curtains Save Energy?

Yes. Air curtains reduce unwanted air exchange, lowering the demand on your heating and cooling systems. This results in significant energy savings over time. For facilities with high traffic, such as warehouses, supermarkets, and retail environments, the savings are even greater.

Applications for Air Curtains

• Industrial door air curtains for warehouses and factories
• Air curtains for dock doors in logistics centers
• Warm air curtains for shop entrances in cold climates
• Garage air curtains to protect vehicle service areas
• Air curtains for retail to improve customer comfort
• Air curtains for industrial doors in production areas
• Recessed air curtains for a discreet, architectural finish

Types of Air Curtains

Commercial Air Curtains

Designed for entrances to shops, offices, and hospitality venues. These units are compact, efficient, and available in electric or ambient versions.

Industrial Air Curtains

Built for durability and performance, industrial air curtains handle large openings and strong pressure differences. Ideal for manufacturing plants and loading bays.

Heated Air Curtains

Hot air curtains and heated air curtains add a warming effect for entrances in colder climates. Available in electric, hot water, or steam-heated models.

Vertical Air Curtains

Mounted vertically alongside an opening, these are ideal for wide entrances where overhead mounting is not possible.

Recessed Air Curtains

Integrated into ceilings or bulkheads for a clean look without visible equipment. Popular in high-end retail and office spaces.

Choosing the Right Air Curtain

• Door dimensions – Width and height determine airflow requirements
• Mounting style – Overhead, vertical, or recessed installation
• Heating options – Heated or unheated depending on climate
• Traffic levels – Match power to pedestrian or vehicle use
• Environmental goals – Focus on energy savings and comfort

Integration with HVAC Systems

Air curtains complement your HVAC system by keeping conditioned air inside and unconditioned air outside. They help maintain stable indoor temperature, improve comfort, and lower energy bills. Some models include smart controls, allowing you to connect with building management systems for automated operation.
