7.1 Capacity Diagram, Sound Data, Specifications - Flexit l12 x W/e
Supply air side (with F7 filter)
Data for supply air is measured in accordance with ISO 5136,
the “In duct method”.
Radiated noise is measured in accordance with ISO 9614-2.
Bruel & Kjær measuring equipment, type 2260.
Blue curves: Air capacity at various capacity settings in Volt.
Green curves: Supply air fan power consumption at various capacity
settings.
Red curves: Sound power level LwA, cf. correction table.
Light blue correction axis: Pressure increase using an EU-5 filter.
Light green correction axis: Pressure reduction using a water battery.
Sound data is given at sound power level LwA in the
capacity diagrams and is corrected with the table below
for the various octave bands. Radiated noise produces
Lw in the various octave bands and total LwA. This is read
directly from the supply air table.
