Air Excellent | 200 series distribution boxes


Injected-moulded plastic distribution boxes are an integral part of Ubbink’s Air Excellent air distribution system and form the hubs for air supply and extract in domestic ventilation systems. Air restrictor rings in the distribution boxes can be used to set the nominal flow rate in each duct run. 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.
