  Invisidor DOORFLOW Air Curtain

The latest development in a long line of market leading air curtains, the DoorFlow has been developed to be not just of minimalist design but also to minimise maintenance, bringing a continuous and consistent long lasting level of performance and maximize energy savings.

  FILTER FREE AIR CURTAIN

  The Invisidor DoorFlow uses Biddle’s proven, patented rectifier to supply conditioned air at low speed with minimum turbulence, ensuring the air stream reaches the floor and doesn’t escape to the outside. Comfort within the entrance area is therefore enhanced without any energy wastage.

  INVISIDOR CITY

  The Invisidor CITY range of air curtains were developed to bring performance benefits and energy and cost savings at a lower installed cost than ever before, being ideally suited to high street stores and other small buildings. Biddle’s CITY incorporates improved structural design and enhanced aesthetic appeal without compromising its award-winning performance.

  Fresh Thinking in Climate Separation
  One of the main functions of an air curtain is to condition outdoor air as it enters the building. For this to be achieved, the airflow must cover the full width of the entrance, so that it cannot be bypassed by incoming air. However, ensuring the airflow reaches the floor level is more difficult, with turbulence at the air outlet being a critical factor.
