Air purifier AirPal 900/1200 U
The unit has two different volume flow or air flow rates as standard. When the Silent Mode button is pressed (the
green button lights up), the unit air flow will reduce (Fig.11). When Silent Mode is activated, the power and unit air flow
will reduce and thus enable quieter operation.
When the Silent Mode button is pressed again, this mode will end and the unit will return to normal operation.
