EC-huippuimuri
AsennusOnnline EC -huippuimuri on helppo asentaa katolle asen-nuskehystä käyttäen.
OhjausEC-huippuimuria voidaan ohjata jänniteviestillä 0 -10 V tai potentiometrillä. Huippuimuri on varustettu EC-ohjaimella, joten sitä voidaan ajaa yhdellä vapaasti säädetyllä nope-udella ilman jänniteviestiä tai sitten kahdella vapaasti säädetyllä nopeudella, jolloin jompi kumpi nopeus valitaan kytkintiedolla (esim. kello).
EC-huippuimuriMateriaali ja rakennePuhaltimen vaippa on valmistettu AluZink-pinnoitetusta teräslevystä. Puhallussuunta on ylöspäin.
Moottori ja siipipyöräSiipipyörä on valmistettu polyamidimuovista, ja siinä on taaksepäin kaartuvat siivet. Moottori on ilmavirrassa, ja siinä on vakiona pyörimisnopeuden säädin.
Toimituksen sisältöHuippuimurin mukana toimitetaan avattava asennuskehys. Moottoriin on tehtaalla asennettu turvakytkin noin 1 metrin kaapelilla.

FAN CHART EXPLANATION AND DEFINITIONS
SYMBOLS
SOUND DATA
The total A-weighted sound power level to surroundings, LwA, can be
read in the fan chart. The correction coefficients Koct by octave bands
can be read in the table below the fan chart. The sound power level
by octave band to the duct or to the surroundings (without A-weight-
ing) can be obtained by using the following formula:
Lwoct = LwA + Koct
SOUND PRESSURE LEVEL AND REMOTE ATTENUATION
Distance L (m) 1 3 5 10 15 20 25 30 40
Attenuation ∆L (dB) 7 17 22 28 31 34 36 37 40
The total sound pressure level to surroundings at different
distances can be estimated using the following formula:
LpA = LwA – ∆L
FAN DATA
The fan data is presented using fan-motor-speed controller
combination. For nominal flow rate, see each size.
The fan data is presented at density 1.2 kg/m2 and tested
according to ISO 5801 and ISO 13347-2.
qv Volume flow rate m3/s, m3/h
∆ps Fan static pressure Pa
Fan max speed r/min
η Overall static efficiency at max r/min %
LwA A-weighted total sound level
to surroundings dB(A)
LWoct Sound power level by octave bands
(without A-weighting) dB
Koct Correction when diving into
different octave bands dB
∆L Remote attenuation (given values
calculated for an ideal case in a halfspace) dB
qnom Nominal flow rate (m³/s)
THE SYMBOLS USED:
Fan code = fan type and size.
Min r/min = minimum fan speed where the sound power level
correction Koct is still applicable.
Max r/min = maximum fan speed where the sound power level
correction Koct is still applicable.
Correction = Sound power level correction factors Koct for the
octave bands 63 to 8000 Hz.
