Notes Sound values are measured in an anechoic room.
Sound pressure level is a relative value, depending on the
distanceandacousticenvironment.Formoredetails,pleaserefer
to sound level drawings of this chapter.
The sound power level is an absolute value indicating the power
which a sound source generates.
The sound pressure level is measured via a microphone at 1m
distance of the unit.

NOTES
1. The wired remote control can be used to switch between ’high’ and ’low’
2. The air flow is set to ’standard’ before leaving the factory.
It is possible to switch between ’standard EPS’ an ’high ’EPS’ by programming on the remote
control.
3. The internal static pressure indicates the characteristics of the fan when a suction panel
(optional accessory) and a canvas for the suction panel (optional accessory) are incorporated
into the main unit (with a long-life filter).
