3.6 Sound Data
Measurement
conditions:
Sound pressure level: 1 meter distance between microphone and the air intake.
Sound power level: Acc. to DIN 45635 part 38 (ISO 10302)
Measured in a semianchoic chamber with a background noise level of Lp(A) < 5 dB(A)
For further measurement conditions see chapter aerodynamics.
a.) Operation condition:
2.500 1/min at free air
flow
PWM 100 %; f: 5 kHz
Optimal operating point 43,0 m3/h @ 157 Pa
Sound power level at the optimal operating
point
6,0 bel(A)
Sound pressure level at free air flow,
measured in rubber bands
The sound pressure level refers to the simultaneous operation of both fans in the unit.

Permitted application area:
The product is for the use in open and unsheltered areas. Direct exposure to water as well as saline ambient
conditions are allowed provided that this does not prevent the normal operation.
Pollution degree 3 (according DIN EN 60664-1)
It occurs conductive pollution or dry non-conductive pollution which becomes conductive due to condensation.
Please require severity levels and specification parameters from the responsible development departments.
