What guarantees the operation of the AFIM® Air Door?
The high pressure Air Door technology ensures a much more effective air separation than the conventional air curtains, for example those applied in department stores.
Conventional air curtain
A conventional air curtain works with huge amounts of air, to which a lot of energy guzzling heat is added.
The AFIM® Air Door
The operation of the AFIM® Air Door on the other hand, works with only a minimal amount of air, which, moreover, does not need to be conditioned. Due to the higher air-pressure, the Air Door cuts through far more effectively than traditional air-curtains, and not a single whiff of air passes the barrier.
For comparison: Conventional air curtains can withstand wind pressure of 0.9 m/s. An AFIM® Air Door can withstand as much as 6 m/s.
Independent research confirmed the effect
