Understanding Air Curtains and Their Purpose
Before evaluating the Air curtain’s lifespan, let’s clarify what an air curtain actually does.
An Air curtain is an electric machine or device that is installed above the door or entrance. It creates a strong invisible Air barrier to protect against dust and flies. It can do much:
- Outside hot air from entering
- Dust and insects
- Odor infiltration
- Temperature imbalance
- Energy loss
An air curtain works by taking the air from your room and blowing it downwards very fast. This fast air creates an invisible barrier, like a shield. Because of this air shield, people can walk in and out easily without closing the door, and outside air, dust, or insects cannot enter.
What Is the Lifespan of an Air Curtain?
The Air Curtain lifespan is one of the most important matters because every buyer wants to buy the best Air Curtain in Bangladesh for long-term use. Mid-quality Air curtain lasts 8 to 12 years, but National Air curtain in Bangladesh or heavy-duty Air curtain lasts 15 to 20 years with regular maintenance or best quality servicing with high expertise.
In my professional work with shops, banks, hospitals, homes and offices in Bangladesh, I have seen that air curtains last for different amounts of time. Their lifespan changes depending on a few important things.
- Motor quality
- Fan blade design
- Usage time per day
- Dust exposure
- Installation height
- Regular maintenance
- Motor watts
- Stainless steel body or not.
✔ Low-end domestic air curtains: 4–6 years
✔ Mid-range commercial air curtains: 6–12 years
✔ High-end industrial air curtains: 12–20 years
When our clients ask, “What is the lifespan of an air curtain?” I always emphasise that proper maintenance extends the operational life by 30–40%.
Key Factors That Affect the Lifespan of an Air Curtain
- Build Quality and Brand
Premium brand quality, like National Brand and the KDK (Panasonic) brand, is used for industrial use.
- Copper-wound motors.
- High speed balanced fans.
- Heat-resistant components.
- Strong housing.
- Higher CFM.
These ensure longer durability for both personal and industrial use.
Cheap or unbranded models often have:
- Weak plastic blades.
- Low-quality bearings
- Poor electrical insulation
- Low motor watts
- Low CFM.
These reduce lifespan significantly. When you buy an Air Curtain, you have to follow these conditions.
2. Daily Usage and Operating Hours
The more you use the air curtain, the faster its parts get old and damaged.
- Heavy Use (15–20 hours/day): 7–9-year lifespan
- Moderate Use (6–12 hours/day): 10–12-year lifespan
- Light Use (1–4 hours/day): Up to 15 years
Commercial spaces like restaurants, warehouses, hospitals, and supermarkets fall into the heavy-use category. There is a need for the best heavy-duty Air curtain in Bangladesh.
3. Maintenance Frequency
One of the main reasons that air curtains stop working is due to a lack of maintenance. Many people think that air curtains do not need any servicing, but they actually do.
Maintenance includes:
- Cleaning dust buildup.
- Checking motor lubrication.
- Servicing bearings.
- Cleaning the inlet/outlet grills.
- Fan alignment inspection.
- Electrical check-up.
Neglecting these tasks can shorten lifespan by 40–50%.
4. Environmental Conditions
Dust greatly affects the Air curtain’s performance.
Spaces with:
- Roadside exposure
- Industrial pollution
- Kitchen oil vapour
- High humidity
If you do not regularly clean, then your air curtain’s lifespan is reduced.
5. Installation Quality
Many people install air curtains incorrectly or inefficiently, which leads to:
- Motor overheats.
- Low airflow pressure.
- Unnecessary vibration.
- Reduced lifespan.
Professionally installed air curtains last longer, save more electricity, and offer consistent airflow. AIRCONcare has skilled technicians for installation and Air Curtain Servicing. You can contact us to buy an Air Curtain or to repair and maintain an Air Curtain.
Signs Your Air Curtain Is Near the End of Its Lifespan
When you see your Air curtain show such a sign, then you should understand that you need to service or maintain your Air curtain.
- Airflow becomes weaker
- Motor overheating and auto-shutoff
- Loud noise or vibration
- Burning smell
- Fan speed fluctuations
- Higher electricity usage
- Low air pressure is reaching the floor
- Motor bearing noise
If you avoid these signs, your Air curtain will then suddenly break down or stop working. It’s a big problem for an air curtain user.
How to Increase the Lifespan of an Air Curtain
1. Clean the Filter and Grill Every 30–45 Days; otherwise, dust buildup is the biggest enemy of motor life.
2. Lubricate Bearings Every 6 Months, which can prevent friction and overheating.
3. Ensure Proper Voltage; otherwise, it can damage your internal circuit.
4. Maintain Correct Installation Height
Standard heights:
- Commercial doors: 7–8 feet
- Industrial doors: 10–12 feet
- Personal doors: 9-10 feet.
5. Regular Servicing can prevent Motor failure.
When customers ask, “What is the lifespan of an air curtain?” I always tell them that proper maintenance is the most important thing to make it last as long as possible.
