The diffuser part may be changed afterwards. The product’s features can be changed to be more suitable for either cooling or heating, if the use of the rooms changes during the product’s lifecycle.

NOT is especially suited for isothermal and low temperature air. NOX is particularly designed for handling overtemperature air. A unique characteristic of NOX is the possibility to turn the vertical throw pattern 30 degrees to the side. This is a huge advantage if the throw pattern becomes obstructed, for example due to changes in the room’s layout.

Model S – quieter than a whisper

The special diffuser models NOT-S and NOX-S have been developed for sites and spaces with especially high sound level requirements. Sounds from adjustment and throttling are efficiently dampened before the diffuser unit.

The solution is visually very stylish as the channel size remains unchanged. Adjustment is performed exactly as in standard models. Typical application sites include schools, offices and daycare centres. The S versions are also well suited for renovation projects where large throttling capacity is required. The dampening material meets cleanliness class M1 requirements.

Features:

• Especially good adaptability and flexibility
• Precise and clear adjustment based on pressure difference
• Excellent air and sound properties
• Easily adjustable installation height
• Ultra low construction height
• Outstandingly easy and fast to clean
• Possibility to replace the diffuser component

NOX-S adjustment unit based on the static pressure difference measurement enables highly accurate air flow measurement and control. The adjustment unit allows a precise adjustment of airflow (± 5%) even at low airflows and duct speeds.

NOX-S is easy to adjust

1. The pressure difference is measured from the measuring socket of the control unit.

2. This adjustment can be made by a screwdriver. The adjustment is done by rotating the control dial with the tool. The control dial readings correspond to separate k-values ​​that can be found on the side of the adjustment unit.

3. The adjustment position can be locked with a screw.
