Open doorways lose conditioned air every minute they stay open. Heat, cold, dust, fumes, and insects move freely across the threshold whenever the door is not shut. This raises energy costs, strains heating and cooling systems, and makes entrance areas uncomfortable for staff and visitors.
The AIRX FM-3515S-L/Y-MC addresses this at the source. It is a 1500mm centrifugal air curtain that pushes a continuous stream of air across the doorway. That air stream forms an invisible barrier that reduces the exchange of indoor and outdoor air while the door remains open.
This page explains what the model does, how it performs, and where it fits. Every claim below ties back to the unit’s actual specifications, so procurement teams and facility managers can verify fit before they buy.
An air curtain is a fan-driven unit mounted above a doorway. It directs a downward sheet of air across the opening, separating two environments without a physical door. This means climate-controlled air stays inside while outside air, dust, and pests stay out.
The FM-3515S-L/Y-MC covers a 1500mm-wide opening, which equals a full five-foot doorway. The AirX 5 Feet Air Curtain suits entrances where a narrower unit would leave gaps at the edges and allow air to slip past.
The model runs on a 220V single-phase, 60Hz electrical supply. This means most commercial and industrial sites can install it on standard wiring without upgrading their electrical service.
The unit uses a centrifugal fan rather than a standard axial fan. A centrifugal fan moves air by spinning it outward through a scroll housing, which holds steady pressure across the full width of the opening.
Axial fans lose pressure across wide spans. On a 1500mm doorway, that weakness shows up as uneven coverage and a broken barrier at the sides. A centrifugal design keeps the air stream uniform from edge to edge. This enables a consistent seal across the whole five-foot opening rather than only the center.
For a wide entrance, this difference decides whether the barrier works or simply stirs the air.
The FM-3515S-L/Y-MC targets high-traffic doors that stay open through the working day. Its core features are:
Each feature points to one outcome: a stable barrier that keeps conditioned air where it belongs.
The 1500mm width matches wider entrances that smaller units cannot seal. A single unit covers a five-foot opening, so there is no need to mount two narrow curtains side by side. This means simpler wiring, cleaner installation, and easier maintenance over the unit’s life.
The centrifugal air curtain delivers a focused, continuous air stream directed straight down across the entrance. Steady pressure across the span keeps the barrier intact even at the outer edges of the doorway.
The unit reduces the direct exchange of indoor and outdoor air through frequently opened doors. Air doors like this one hold the interior climate steady while people and goods move through the opening. This keeps entrance zones closer to the target temperature during peak traffic.
The model is built for demanding environments such as shops, restaurants, offices, hotels, and industrial premises. It is rated for the duty cycles those spaces demand, where doors open and close hundreds of times a day.
The unit operates on 220V single-phase, 60Hz supply. This matches common commercial and industrial outlets, so most sites avoid electrical upgrades before installation.

The 220V single-phase supply matches standard site wiring, which means most locations can install the unit without changing their electrical service.
Wide entrances lose the most air because the opening is large and traffic is constant. The FM-3515S-L/Y-MC targets exactly these locations with a 1500mm air stream sized for the full doorway.
The 60 inch Centrifugal unit suits the following environments:
In each case, the goal is the same. Keep conditioned air inside, keep outside air and contaminants out, and reduce the load on the building’s heating and cooling system.
Match the curtain to the doorway. The AirX 5 Feet Air Curtain is intended for openings close to 1500mm wide. A unit narrower than the door leaves unprotected gaps at the sides, which weakens the barrier.
Mount the unit directly above the door and as close to the frame as practical. Correct height and placement keep the air stream aimed straight down across the opening. This positioning is what allows air doors to seal the entrance effectively.
A centrifugal air curtain delivers measurable operational value in busy spaces. The main benefits are:
These outcomes matter most where doors cannot stay closed. A retail store or a warehouse with constant movement cannot rely on a shut door to hold its climate. The barrier fills that gap.
Standard air curtains often use axial fans and target narrow residential or small commercial doors. They struggle on wide openings where pressure has to hold across a longer span.
The 60 inch Centrifugal model is built for the opposite case. Its centrifugal fan and 1500mm width address wide entrances directly. This means one unit covers a five-foot door without stacking two smaller models side by side.
For sites with large doorways, a single correctly sized unit is easier to install, wire, and maintain than several smaller ones. That is the practical reason wide-format buyers choose air doors in this format over general-purpose alternatives.
What doorway width does the FM-3515S-L/Y-MC cover?
The unit is designed for 1500mm-wide doorways, which equals a full five-foot opening. It covers that span as a single unit, so no second curtain is needed for standard wide doors.
What power supply does this air curtain need?
It runs on 220V single-phase power at 60Hz. This matches common commercial and industrial wiring, so most sites install it without electrical upgrades.
Does an air curtain replace a physical door?
No. It reduces air exchange while a door is open, but it does not seal the opening like a closed door. Its purpose is to protect climate control during the hours a door stays open.
Can this model be used in restaurants and cafés?
Yes. The moving air stream helps keep insects and street air out of dining and food-prep areas, which is a common reason food businesses install a five-foot curtain over the entrance.
Where should the unit be mounted?
Mount it directly above the doorway, close to the frame, so the air stream aims straight down across the full opening. Correct placement is essential for an effective barrier.
Is this unit suitable for warehouses and workshops?
Yes. The 1500mm width and centrifugal air curtain design suit large operational doorways where doors open frequently throughout the day.
Does an air curtain save energy?
It reduces the volume of conditioned air escaping through open doors. This lowers the workload on heating and cooling systems, which supports lower energy use over time.
The AIRX FM-3515S-L/Y-MC is a 1500mm centrifugal air curtain wired for 220V single-phase, 60Hz supply and built for doorway installation. It forms a continuous air barrier that limits the exchange of indoor and outdoor air through open doors. For retail stores, restaurants, hotels, offices, warehouses, workshops, and industrial entrances, this unit keeps conditioned air inside and outside contaminants out, matching the demands of a wide, busy doorway with a single correctly sized unit.
