As buildings become better insulated and airtight, purposes provided ventilation is required to create and sustain a healthy and comfortable indoor air quality. The effectiveness of central mechanical ventilation systems with heat recovery are largely dependent upon the system used to distribute the air and the ductwork are the blood vessels in modern, energy-efficient buildings. However, A poorly designed or installed air distribution the system will waste energy through unnecessary pressure loss and/or air leakage because the ventilation unit will have to work harder to ventilate at the required rates, which may also, cause unnecessary noise hindrance.
“ We are a specialist in ventilation ductwork and we have developed air distribution systems which help create and sustain healthy and comfortable indoor climates”
Air Excellent in a nutshell
· Hassle Free Design
· Straightforward layout and realization.
· Comfortable indoor climate.
Radial systems are more effective
Radial ductwork systems diff er from traditional trunk and branch ductwork systems by running ducts
between a distribution box and each habitable and wet room. The distribution box is then connected
to a ventilation unit using mass fl ow ductwork and a silencer.
· The system pressure drop is lower as a result.
· Continuous duct runs with mechanical connections at either end also mean less air leakage.
· The ventilation rates can be controlled by fl ow restrictors in the distribution box.
· Cross-talk between rooms is reduced to an absolute minimum.
Full control
Air Excellent has been developed to speed up design, installation and commissioning.
“Air Excellent is BIM-ready and continuously being updated and optimized”
Design
All Air Excellent parts are available as Auto desk Auto Cad and Autodesk Revit files enabling a fully automated and BIM-ready project planning. This not only helps create an accurate bill of material, but more import antly tackles potential problems off -site, i. e. before installation.
Balancing
The Air Excellent system comes with an online commissioning tool, which provides detailed information about the system pressure, a bill of material, and last but not least the flow restrictor settings per duct run. The flow restrictors are an essential part of the Air Excellent system since it is the tool to adjust the right airflow to the right room of the building. The Air Excellent commissioning tool calculates how to alter the restrictor. The calculation can be amended on-site if the installed system differs from its original design.
Installation
Ductwork on a roll is easy to layout, cut to length, and bend around obstacles. Mechanical connections, deliver quick, clean, and consistent quality air-tight connections, which makes Air Excellent ideal for pre-fabricated construction. The ductwork can be laid under screed floors, suspended under ceilings, and hung in walls.
Ductwork details
Mass Flow Duct Work
Although not part of the Air Excellent portfolio, mass fl ow duct work and silencers are essential parts of the ventilation system. Insulated mass fl ow ducts in air distribution systems used for ventilation, heating or cooling is often required to minimize heat loss or prevent condensation on or inside the duct. Silencers, which are placed between the ventilation unit and the distribution boxes, minimize the transfer of sound produced by the ventilation unit.
Distribution boxes
The distribution box is an important part of radial ventilation systems, like Air Excellent. It connects between the ventilation unit and the valves that are installed in the habitable and wet rooms. Within the distribution boxes, the air capacity to the duct runs can be adjusted by air fl ow restrictions that are mounted in the duct work connections of the distribution box. The type of distribution box required, depends on the total volume required, the number of duct runs and the desired system performance. The Air Excellent online configuration is a great help for determining a complete system.
The 200 Series distribution boxes
The 200 Series distribution boxes are a modular system that can be characterized by functional partitioning into scalable and reusable modules, interfacing with a constant changing building environment. The system consists of basic box configurations, extension kits and adapters that can be merged to function as one system. This allows tailor-made solutions for any installation and prevents over-sized installations. Its small dimensions make it ideal for residential buildings that require lower air volumes or buildings that have limited installation space. Installations do not require separate mounting brackets and can be executed by a single person on walls, floors and ceilings. 16 one system.

The DB208 distribution box
The DB208 distribution box comes standard with 8 ductwork connections for the basic box with two ductwork connection on each side. Mass flow ductwork can be connected vertically with stepped adapters for 100/125 mm and 125/150/160 and 180 mm mass flow ductwork.
The DB206 distribution box
The DB206 distribution box comes standard with 6 ductwork connections for the basic box and an oval side connection that can be used for inspection, cleaning, changing flow restrictors or connecting mass flow ductwork. Mass flow ductwork can also be connected vertically offering several installation possibilities
