Best Air Curtain for Shops in the UAE
An air curtain over a shop door keeps conditioned air in and hot, dusty air — and insects — out, while letting the door stay open for customers. In the UAE, where the temperature difference across a doorway can exceed 20 °C, a correctly sized air curtain pays back quickly in AC running cost. This guide explains how to choose one and lists the Nanyoo models BOTANVE stocks.
Sizing to the doorway
| Doorway | Recommended width | Nanyoo model | Price (sensor / sensor+remote) |
|---|---|---|---|
| Single door up to 0.9 m | 0.9 m | 0.9 m | AED 230 / AED 245 |
| Wide single door 1.0–1.2 m | 1.2 m | 1.2 m | AED 290 / AED 305 |
| Double door 1.4–1.5 m | 1.5 m | 1.5 m | AED 345 / AED 360 |
| Double door 1.6–1.8 m | 1.8 m | 1.8 m | AED 380 / AED 395 |
| Wide entrance 1.9–2.0 m | 2.0 m | 2.0 m | AED 495 / AED 510 |
0.6 m and 1.0 m models are also available. The unit should be at least as wide as the opening; for wider entrances, mount two units side by side. See what size air curtain do I need.
Sensor or sensor + remote?
Both versions switch on automatically when the door opens via the supplied sensor. The sensor + remote version adds a handheld remote for manual on/off and speed selection — useful in cafés and clinics where staff want to run the unit continuously during peak hours or lower the speed at quiet times. The price difference is AED 15 across the range.
Mounting height and airflow
Nanyoo FM-series units are rated for a recommended mounting height of 2.3–3 m with air velocity around 10.5 m/s at the outlet. Above 3 m the air stream weakens before it reaches the floor and the seal breaks; see the installation height guide. Airflow rises with width — from 1,480 m³/h on the 0.9 m unit to 3,480 m³/h on the 2.0 m unit.
What to check before buying
- Clear door width and height, and whether the door is single or double.
- Power point near the top of the frame (220–240 V, 50 Hz).
- Exposure to wind — sea-facing shops in Dubai Marina or Fujairah may need a higher-velocity unit.
- Noise — Nanyoo FM units are rated ≤45 dB on the 0.9 m model; check the product page for your size.
- Quantity — for multiple outlets, request a bulk quotation.
Frequently asked questions
What is the best air curtain for a small shop?
For a standard single door, a 0.9 m or 1.2 m Nanyoo sensor unit at AED 230–290 covers most UAE shops.
Do air curtains work in UAE heat?
Yes — they are most effective where the indoor/outdoor temperature difference is large, as it is in the UAE summer, provided the unit is sized and mounted correctly.
Do I need a heated air curtain?
No — in the UAE ambient (non-heated) units are used; the aim is to keep hot air out, not to heat the entrance.
Can one unit cover a 2.4 m entrance?
Mount two units (e.g. 1.2 m + 1.2 m) side by side with no gap.
