s The specified sound levels dB(A) are applicable to
rooms with an equivalent sound absorption area of 10
m2 (4 dB room attenuation).
s The throw L0.2 is measured under isothermal discharge
conditions.
s Recommended max. permitted temperature below
room temperature is 12 K.
s All technical data applies to 360° distribution pattern.
s For calculating the air stream propagation, air velocities
in the occupancy zone, or sound levels in rooms with
other dimensions, we refer to our ProAir Web calculation
program. ProAir Web is available at www.swegon.com.
Air flow – Pressure drop – Sound level – Throw
s The diagrams should not be used for commissioning.
s The dB(C) value is normally 6-9 dB higher than the
dB(A) value.
s Sizing example – size 160:
– Given airflow 10-50 l/s at Pt 50 Pa.
– Max. sound level 27 dB(A)
– Throw = 2,0 m
