Separate duct system from BORA

BORA Ecotube and BORA 3box are the new components in the BORA system. To achieve perfection and provide a 100% function guarantee, BORA has developed its own duct system with optimally coordinated products all the way to the wall conduit. A system is available now, which does justice to the high requirements of efficiency, ease of installation and flexibility. You also get additional advantages in ordering and installing, since everything comes from a single source and consequently makes everything easier.

BORA Ecotube Advantages

  • Comprehensive solution
  • Oval cross-section for optimized flow
  • Fire protection class V0 (according to UL94) and building material class B1 (according to DIN 4102-1 classification)
  • 20% less pressure loss
  • Unique sealing concept and easy installation
  • Smooth, highly polished surfaces in the air-conducting areas

BORA 3box (UEBF) Advantages

  • Comprehensive solution
  • Simple, mechanical, non-fault-prone operating mode
  • No additional cable routing required for power supply or sensor system
  • Low pressure resistance
  • Resistance to environmental influences (water tightness under heavy rain, etc.)
  • Drainage of condensation and rainwater
  • 3-fold insulated, lower U-value
  • Insulation between the masonry and the BORA 3box
  • Easy adaptation to different wall thicknesses
  • Easy installation
