Invisidor DoorFlow2 Comfort Air Curtain

Comfortable and inviting
Shops and public buildings often have open doors for commercial reasons. The DoorFlow comfort air curtain model proves that it is possible to keep your shop door open whilst maintaining a comfortable indoor climate.  By installing a DoorFlow over the open door, you are saving vast amounts of energy as well as preventing draughts. 

The DoorFlow model is easily maintenance. As the device has no filters, you will not have to devote any time to cleaning and replacing them.

    • Trendy design

  • Patented Rectifier Technology

    The Biddle air curtains SR and DoorFlow are equipped with the patented rectifier technology. This results in the following advantages: 

    Significant climate separation efficiency (90%)
    Excellent downward penetration
    Laminar air flow  
    Air curtain warmth benefits the indoor climate 

    Without rectifier: large air displacement 
    With rectifier: perfect climate separation

    High yield
    Because of the difference in temperature between inside and outside areas, air always moves in the vicinity of an open door: warm air streams in and cold air streams out. The patented rectifier ensures that the air turbulence caused by the fans is transformed into a laminar air stream. The air stream reaches the floor at a much lower air speed than air curtains without the rectifier. The tight air stream prevents cold air from streaming out. This achieves a climate separation efficiency of over 90%.
