Commercial and Industrial Air Curtains

KCVENTS air curtains help create an air barrier across commercial and industrial doorways. Choose by opening width and height, traffic, wind exposure, air velocity, heating requirement, mounting and electrical control, then verify the latest product data before ordering.

An air curtain is selected by the doorway opening, mounting height, required air velocity and operating condition. Start with the clear width and height, traffic pattern, indoor/outdoor temperature difference, heating requirement and available power. Then confirm the model's airflow, sound, mounting method and duty point on its product page.

Quick answer

Use cross-flow models for common retail and office entrances; use centrifugal models when the opening, pressure difference or operating environment requires more air velocity. A heated model addresses cold-season comfort but does not replace a ventilation design.

Elevator

The product page lists a compact 800 mm unit for 2.5-3 m installation heights and elevator entrances.

X5 centrifugal

The X5 page lists 20 m/s outlet velocity and 900-1800 mm model lengths for higher-demand entrances.

Heated entrance

The Heating Air Curtain uses PTC heating; confirm heat output, control mode and electrical variant for the project.

Product path Current page evidence Project question
Elevator Air Curtain Lists 860 m3/h, 7.5 m/s, 80 W and an installation height of 2.5-3 m. Does the body length and mounting height suit the elevator header?
Cross-Flow B series Lists 11-13 m/s versions and 900-2000 mm model coverage. What outlet velocity and length are needed for the entrance width?
Industrial centrifugal Lists up to 30 m/s and 900-1800 mm models for industrial entrances. What duty point is needed under wind and pressure conditions?

Specification basis: the linked KCVENTS product pages currently state the values shown above. Confirm the latest dimensions, sound data, velocity profile, electrical variant and installation instructions before ordering.

"Indoor air is the dominant pathway for exposure to airborne contaminants given that people spend the majority of their time indoors, and indoor air commonly contains numerous contaminants originating from both indoor and outdoor sources."

The World Health Organization has published a roadmap for improving indoor ventilation to reduce the risk of airborne disease transmission. This is a public-health reference for ventilation design; an air curtain is a door-opening air barrier and does not by itself supply the outdoor-air ventilation the roadmap refers to. See the WHO publication.

Air curtain buying questions

Use these questions to prepare a doorway equipment enquiry.

Does an air curtain replace mechanical ventilation?

No. An air curtain forms an air barrier at an opening. Outdoor-air ventilation, filtration and exhaust still need their own design and code review.

How should an air curtain be sized?

Start with the clear opening width and height, mounting position, wind exposure and required outlet velocity. Check the fan curve and airflow profile at the actual installation condition rather than selecting by door width alone.

When is a heated air curtain appropriate?

Use a heated model when cold outdoor air at an open entrance affects comfort and the electrical supply can support the specified heat level. Confirm the heating control and local electrical requirements.

What should be included in a quotation request?

Provide opening dimensions, mounting height, indoor/outdoor conditions, traffic pattern, heating preference, voltage, control method, quantity and required installation or test documents.

Need a model recommendation?

Send the application, required airflow, wall construction, target market, voltage or plug requirement, certification needs and estimated quantity.

KCVENTS can then confirm the suitable model variant, available controls and the documentation required for your project.
