Air Curtain
Product Code : EL-LEAA-11013
Air Curtain (code EL-LEAA-11013) is a blower unit that sends a stream of air across a door opening to reduce overloading of refrigeration and air conditioning systems. It is offered in 2, 3, 4, 5 and 6 ft and 1 and 2 m sizes for door heights up to 30 feet, and has statically and dynamically balanced stainless steel impellers driven by a 180 W double shaft motor with thermal overload protection, on 230 V AC, 50 Hz.

What Is the Air Curtain Used For?
When a door to a cold room, air-conditioned laboratory or store is opened, warm outside air flows in and conditioned air escapes, which adds load to the cooling plant. An air curtain fitted above the opening blows a high-velocity sheet of air downwards across it, forming a barrier that reduces this exchange while people and trolleys pass through. The unit is chosen to match the door width, the built-in regulators set the air speed, the double shaft motor drives the impellers for continuous operation, and thermal overload protection switches off the motor before it can burn out.
What to Specify When Ordering
- Quantity — the number of air curtains required.
- Size — 2, 3, 4, 5 or 6 ft, or 1 or 2 m, to match the door width.
- Door height — the height of the opening, up to 30 feet.
Frequently Asked Questions
What sizes are available?
It is made in 2, 3, 4, 5 and 6 ft sizes and also in 1 m and 2 m sizes, for door sizes up to 6 ft.
What air velocity does it give?
Air velocities of 11, 15, 18, 21, 25 and 28 m/sec are listed, and a separate air velocity of 20 to 22 m/s is also given.
How is the motor protected?
The motor has automatic thermal overload protection that safeguards it from burnout, and it is a double shaft motor meant for continuous operation.
What electrical supply does it need?
It operates on 230 V AC at 50 Hz with a power rating of 180 W, and the speed regulators are built into the unit.
How does an air curtain reduce cooling load?
Its stream of air across the doorway limits the warm air that enters and the cool air that escapes while the door is open, so the refrigeration or air conditioning plant is not overloaded.
What details are needed for an export enquiry?
For export, send the quantity and sizes, the country of destination with its port or city, the Incoterms wanted (for example FOB or CIF), any special packing and the tender reference if the purchase is under a tender.
