Airflow ‘+’

Thanks to its humidity sensitive system, this extract unit automatically adapts its airflow to the humidity of the air in each room, providing optimum ventilation and reducing heat loss. An additional airflow can also be activated if required (by switch). 

Pressure plug to help commissioning

In addition to its efficiency, this humidity-controlled extract unit has been designed to make it easier to bring your ventilation system into compliance. In fact, the airflow range can be adjusted at installation to compensate excessive pressure drops and thus adjust the airflow through the unit. This measurement is made easier by the presence of a pressure plug.

An aesthetic mask

The cover plate allows the technical part of the extract unit to be completely concealed to blend in with the room. It has a simple, uncluttered design to bring a touch of modernity to ventilation equipment. In addition, it can be customised thanks to its paintable material.

Note: airflow given for a ø100 duct
(1) Default setting.
(2) Tolerance : 12m3/h +/- 3  ,  80m3/h +/- 10.
(3) Airflow ‘+’: the airflow can be increased from +10 m3/h to +50 m3/h (6 positions available). This function can be used to adapt to lower pressure or to specific regulations imposing higher airflows. Standard is position 0 (minimum airflow = 12 m3/h @ 100 Pa).
