Description

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.

NOP and NOT are 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.

NOP is a part of the OptiFlow® product family!

OptiFlow® products adapt to changes in the life cycle of the space due to an optimized and adaptable throw pattern.

NOP adjustment unit

NOP 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.

NOP 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.
