BIDDLE Invisidor City Air Curtains

The Invisidor CITY range of air curtains has been 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 relatively small buildings.

Using Biddle’s patented rectifier the conditioned air is supplied 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.

Designed with rounded profiles and an eye-catching perforated grille, Invisidor CITY air curtains are modular in nature enabling any door width to be covered. And buildings with low water temperatures, from a condensing boiler, can still benefit by using a specially developed CB version of the Invisidor CITY air curtain.
