How to select Air Curtains

There are numerous factors that we have to consider when selecting an air curtain, some of which are listed below:

  1. Application
  2. Door height
  3. Outside wind
  4. Building static pressure
  5. Door structure
  6. Ambient temperature
  7. Air curtain size
  8. Air curtain design and look
  9. Noise level
  10. Power consumption

In normal cases, we can make preliminary selection by considering factors (1) – (4). And since factors (3) and (4) resulted in either an inward or outward airflow through the doorway, we group them together and called it collectively as “air infiltration through the doorway” (measured in m/s or fpm).

We eventually summarized the selection guides into a graphical presentation as shown below.
