Invisidor DoorFlow has been carefully developed to minimise maintenance. A purpose designed coil/heater battery reduces the build-up of dust and debris between the coil fins to such an extent that filters are no longer necessary. Having no filters means the Invisidor DoorFlow doesn’t just offer minimal maintenance but also provides a continuous and consistent long-lasting level of performance.
PATENTED RECTIFIER TECHNOLOGY
So as to minimise turbulence in the discharge airstream, and ensure the air reaches the floor, Biddle have invested heavily in the development of the patented rectifier. This rectifier comprises an optimised number of blades, with a precise relationship between their length and spacing, to create a laminar airstream which reduces turbulence and energy consumption and increases throw for a given air volume.
