Fedon Air Curtain

A high-velocity invisible air barrier for doorways that keeps flies, dust and outside air out — while holding conditioned air in. Engineered for restaurants, pharma, hospitals, retail, cold storage and high-traffic entrances.

Fedon™ Fedon air curtain — wall-mounted commercial air curtain unit
Commercial & Industrial Air Curtain

An Invisible Wall of Moving Air

The Fedon air curtain mounts above a doorway and projects a continuous, high-velocity stream of air downward — creating an invisible barrier that separates two environments. It keeps flies, dust and outside air out while maintaining temperature and air quality inside.

With air velocity of 18–21 m/s, it is physically impossible for flying insects to penetrate the curtain. Available with or without a door sensor, it cuts HVAC load and AC energy costs while running at less than the volume of normal conversation.

Simple 3-Step Mechanism

How the Air Curtain Works

Mounted directly above the door frame, the unit drives a controlled jet of air across the entire opening — sealing the doorway without ever closing it.

Activate
The sensor model switches on the instant the door opens; the standard model runs continuously while powered — ready the moment the entrance is in use.
Blast
Centrifugal blowers drive a high-velocity air stream of 18–21 m/s straight down across the doorway, spanning the full width of the opening.
Seal
The moving air forms an invisible wall that flies, dust and outside air cannot cross — while conditioned air stays sealed inside, cutting energy loss.

Sensor vs. Standard

Smarter Running, Lower Bills

Every Fedon model is available in a sensor or non-sensor variant. The sensor version powers the air stream only when the door opens — ideal for moderate-traffic entrances where it maximises energy savings.

The standard version runs continuously while switched on, the best fit for high-traffic doorways that stay busy throughout the day. Either way, the curtain reduces HVAC load and AC energy costs by 30–50% by sealing conditioned air inside.

Mount inside, above the door frame Up to 3 m mounting height

Frequently Asked Questions

Answers to the most common questions about Fedon industrial air curtains.

What is an industrial air curtain and how does it work?
An industrial air curtain creates a powerful stream of air across a doorway, forming an invisible barrier that helps keep dust, insects, heat, and pollutants from entering while retaining conditioned indoor air.
Who are the best air curtain manufacturers and suppliers in India?
Fedon Air Curtains are trusted by factories, restaurants, hospitals, warehouses, retail stores, and commercial facilities across India for reliable entrance protection and energy efficiency.
What size air curtain do I need for my door or commercial entrance?
The right air curtain depends on the width and height of your doorway. Fedon Air Curtains are available in multiple sizes to suit small entrances, commercial doorways, and large industrial openings.
Do industrial air curtains actually keep flies and insects out?
Yes. Fedon Air Curtains generate air velocities of 18–21 m/s, creating a strong air barrier that helps prevent flies, mosquitoes, and other flying insects from entering through open doors.
