• Distribution boxes
• Semi-rigid ducts:
  • 3 circular DN’s: 75/63, 90/75, 63/50
  • 3 semi-circular dimensions: 100*50, 140*50, 130*60
• Duct accessories, including an airtight, mechanical sealing mechanism, duct connectors, bends and supply and extract valve adaptors.
• Valves and grilles

Easy installation guaranteed

• The ventilation unit is connected to the Air Excellent distribution boxes using insulated, mass flow ductwork and/or sound attenuators.
• The semi-rigid Air Excellent ducts are rolled out from the distribution boxes to the habitable rooms and wet rooms; preferably in single pieces.
• The mechanical connections used to connect the ducts to the distribution boxes and duct accessories are not only airtight, but much easier, quicker and cleaner to install than using sealants and/or adhesive tape. This ensures that the ductwork system remains airtight and the ventilation unit doesn’t have to work harder than is necessary and by doing so waste energy and produce more sound/make more noise than is necessary to ventilate ‘right’.
• Designers and installers can use Ubbink’s online commissioning tool to calculate how many rings to cut out for each duct run. The air restrictor rings are very easy and quick to install, which will save a lot of valuable time on-site compared to traditional methods of commissioning ventilation systems.
