Every time a commercial door opens, conditioned air escapes and outside air rushes in. In high-traffic entrances, that exchange happens hundreds of times a day, forcing HVAC systems to work harder and raising energy costs. The AIRX 3 Feet Air Curtain solves this by pushing a steady stream of air across the doorway, forming a barrier that separates indoor and outdoor conditions without blocking movement.
The AIRX FM-3509S-L/Y-MC is a 900mm centrifugal air curtain built for installation above commercial and service entrances. It delivers continuous, focused airflow across a 900mm (36-inch) opening, reducing the movement of air between inside and outside whenever the door stays open. This model suits shops, offices, restaurants, and other spaces that need a compact 90cm barrier.
Open doors create a constant problem: heated or cooled air leaves the building while dust, insects, and outside air move in. The more often the door opens, the greater the loss and the harder the interior climate is to hold.
The FM-3509S-L/Y-MC interrupts that cycle. Its centrifugal fan produces a focused airstream that spans the full 900mm width of the opening. The moving air forms a barrier that resists the natural exchange between two temperature zones. This means the building holds its indoor climate with less strain on the cooling or heating system.
The unit mounts above the door, so it occupies no floor or wall space at eye level. Staff and customers pass through without obstruction, and the barrier reforms the moment they clear the opening. For entrances that open constantly, that fast recovery is the practical difference between stable comfort and steady loss.
The fan type determines how well an air curtain performs. This model uses a 36 inch Centrifugal fan, which draws air inward and forces it outward before directing it down across the doorway. Centrifugal fans generate higher pressure than simple axial fans, so the airstream reaches the floor with force intact.
That pressure matters at the threshold. A 36 inch Centrifugal unit covers roughly 90cm of door width with a uniform curtain, leaving no weak gaps where outside air can slip through. The result is even coverage from one edge of the frame to the other.
Focused airflow also limits the entry of dust, insects, and airborne particles when the door stays open. The 36 inch Centrifugal system keeps that barrier active during peak traffic, which helps maintain a more controlled indoor environment throughout the day.
The FM-3509S-L/Y-MC runs on a 220V single-phase supply at 60Hz frequency. Single-phase power means the unit connects to standard commercial wiring without a three-phase circuit. This simplifies installation in most retail and office buildings.
The Airx air Curtain installs above the door, directly over the frame. Mounting height and door width should match the 900mm coverage the unit is designed to deliver. When sized correctly, the Airx air Curtain produces a continuous downward stream that holds the barrier across the entire opening.
This Airx air Curtain model targets compact and standard-width entrances. Its 36-inch span fits single wide doors, service entrances, and shop fronts where a full-width barrier is required without the footprint of a larger unit.

This unit fits any commercial space where doors open frequently and indoor conditions need to stay stable. The FM-3509S-L/Y-MC works across a range of settings:
Each of these settings shares one issue: a door that opens too often to hold its climate on its own. The FM-3509S-L/Y-MC addresses that directly by keeping the barrier active regardless of traffic volume.
Airflow strength decides whether a barrier reaches the floor or fades halfway down. A weak stream leaves a gap at ground level where outside air, dust, and insects slip through.
The centrifugal fan system in the FM-3509S-L/Y-MC delivers a focused, consistent airstream across the entrance. This enables the unit to hold a full-height barrier from the mounting point to the floor. The result is a stable indoor environment even when the door stays open during peak hours.
Frequently opened doors expose interior spaces to outside contaminants. Dust settles on stock, insects enter food-service areas, and outdoor air disrupts the set temperature.
The air Curtain barrier reduces the entry of dust, insects, outdoor air, and airborne particles through the doorway. This makes the unit suitable for shops, offices, restaurants, showrooms, and other commercial spaces where cleaner indoor conditions matter. As a first line of defense at the threshold, a well-sized air Curtain reduces the load on interior filtration and helps maintain air quality inside.
For buyers comparing options, the FM-3509S-L/Y-MC stands out as the best air Curtain choice for compact entrances that need full coverage without a larger unit. Matching the barrier to the door is what makes the best air Curtain setup effective, and this model is built for that fit.
Not every entrance needs a wide unit. Oversizing an air Curtain wastes power and complicates mounting on standard door frames.
With a 900mm (36-inch) width, the FM-3509S-L/Y-MC suits standard-size entrances and commercial doorways where a compact installation is required. The 90cm footprint fits tight above-door spaces while still covering the full opening. This means buyers get complete coverage without paying for width they do not need, which is why the compact build is often the best air Curtain fit for smaller commercial fronts.
The unit covers a 900mm (36-inch) opening. It suits single wide doors, shop fronts, and service entrances that need full-width coverage in a compact size.
The unit runs on 220V single-phase power at 60Hz. Single-phase wiring is standard in most commercial buildings, so no three-phase circuit is required.
A centrifugal fan generates higher pressure than an axial fan. This means the airstream reaches the floor with force intact and covers the full door width without weak gaps.
Mount the unit above the door, directly over the frame. Correct mounting height and alignment let the barrier span the entire 900mm opening.
Yes. The barrier limits dust, insects, and airborne particles from entering. Acting at the threshold, it reduces the load on interior filtration and supports cleaner indoor conditions.
Shops, offices, restaurants, showrooms, commercial buildings, and service entrances all benefit. Any doorway that opens frequently and needs a compact barrier is a strong fit.
The FM-3509S-L/Y-MC gives commercial buildings a straightforward way to hold indoor comfort, cut energy loss, and keep entrance air cleaner throughout the day. Check availability and add this model to your cart to protect your entrance today.
