Motor Position 

The position of the motor for belt drive centrifugal fan is 

in accordance with AMCA standard 99-2407-66. 

Location of motor is determined by facing the drive side of fan 

and designating the positions by letters W, X, Y, or Z . 

[refer to Fig.4] 

Fig. 4 - Motor Position 

Motor Selection 

The power curve shown on each performance curve represents 

the absorbed power at the shaft of the fan measured in kW. 

To determine the power of the motor to be installed, a 

correction factor as shown in fig. 5 should be applied 

to compensate for transmission losses. 

For conversion to horsepower (HP), use multiplying factor 

1.34.Utpat. Ostionsequat volutat illaor iurercil essequat.

Dynamic Pressure 

FDA 

Series 

The dynamic pressure and outlet air velocity shown on each curve are calculated 

on the full air discharge area, i.e. ducted outlet conditions. 

With free outlet conditions, the velocity pressure is higher. To determine this new value, multiply the velocity 

pressure of the ducted outlet obtained from the fan curve by the following correction factor “K”. 

Fan performances calculate with this correction factors are not licensed by AMCA. 

[ K = 2.6 ] 

Performance 

The performance data shown on each diagram has been tested and measured in accordance to AMCA 

Standard 210 – Fig 12 – installation type B (free inlet and ducted outlet conditions). 

Ratings are referred to the standard air density with the total pressure as a function of the air volume, using logarithmic scales. 

It is essential that, the same installation type and test standards are used at all times, when comparing fan performances. 

Noise 

The noise level shown on each diagram refer to the sound power “A-weighted” and the data on the inlet side has been measured 

in accordance with AMCA Standard 300 diag. 2 - configuration “B”. The noise levels of the fans are determined as follows: 

– Sound power level - (“A” scale): Lw (A) as catalogue. 

– Octave band spectrum: Lw = Lw(A) + Lw rel. dB [refer to Soler & Palau S.A. for more details]. 

– Sound pressure level: 

a) free field 

Lp(A) = Lw(A) - (20log 10 

d) -11 

b) room conditions 

Lp(A) = Lw(A) - (20log 10 

d) -7 

where d = distance of fan (m)

Series 

The dynamic pressure and outlet air velocity shown on each curve are both calculated 

on the full air discharge area, i.e. ducted outlet conditions. 

With free outlet conditions the velocity pressure is higher. To determine this new value, multiply the velocity 

pressure of the ducted outlet obtained from the fan curve by the following correction factor “K”. 

[ K = 1.67 ] 

Fan Performances calculated with this correction factors are not licensed by AMCA. 

Performance 

The performance data shown on each diagram has been tested and measured in accordance to 

AMCA Standard 210 [Fig 12] installation type B (free inlet and ducted outlet condition). 

Rating are referred to the standard air density with the total pressure as a function of the air volume, using logarithmic scales. 

It is essential that, the same installation type and test standards are used at all times, when comparing fan performances. 

Noise 

The noise level shown on each diagram refer to the sound power “A-weighted” and the data on the inlet side has been tested and 

measured in accordance with AMCA Standard 300 diag. 2 - configuration “B”. The noise levels of the fans are determined as follows: 

– Sound power level - (“A” scale): Lw (A) as catalogue. 

– Octave band spectrum: Lw = Lw(A) + Lw rel. dB [refer to Soler & Palau for more details]. 

– Sound pressure level: 

a) free field 

Lp(A) = Lw(A) - (20log 10 

d) -11 

b) room conditions 

Lp(A) = Lw(A) - (20log 10 

d) -7 

where d = distance of fan (m)
