1 for pressure series from 100 dapa to 3150 dapa Sound tables according to types for pressure series from 100 dapa to 3150 dapa Weight list and noise values for standard motors Performance curves 1 to 7 Handbook Radial Fans / Chapter 2 - REITZ List 2010 TA 1

2 Coents on type selection V 0 = V 1 f V0 = calculation of actual volume at vaccuum operation; index 1 for inlet operation (Δpt 1 ); index 2 for discharge operation (Δpt 2 ) (coent on see sheet PB 23) pressure series 100 dapa dapa = 1.00 pressure series 315 dapa = 0.98 pressure series 355 dapa = 0.97 pressure series 400 dapa dapa = 0.96 pressure series 500 dapa = 0.95 pressure series 630 dapa = 0.94 pressure series 800 dapa = 0.93 pressure series 1000 dapa = 0.91 pressure series 1250 dapa = 0.89 pressure series 1600 dapa = 0.86 pressure series 2000 dapa = 0.84 pressure series 2500 dapa = 0.80 pressure series 2800 dapa = 0.72 pressure series 3150 dapa = 0.69 Symbol o only possible for type MX 1. The recoended motor may possibly differ from the motor that actually must be chosen with regard to starting behaviour which depends on the motor make. Furthermore, motor selection must also consider the change of shaft power at sequences through the performance curve beyond the nominal point.therefore, a) starting, starting behaviour, starting times and motor protection must be observed (see sheets PB 13 to 15) b) heavy-duty starting must be provided c) the customer should always check the main power supply, the switching devices and monitoring equipment with respect to starting mode and current peak values and have them adequately dimensioned d) it is recoended to use protective motor devices with PTC-thermistors e) the actual shaft power has to be checked when the nominal point of the performance curve is exceeded. Subsequently the actual motor power to be installed has to be adjusted. (see sheet PB 22). 2. Applies to drive motors listed in the type selection with a starting torque which is as high as 2.2 times the nominal torque. 3. Shaft power in nominal point for type KX Shaft power for types RG = Pw ( ) Observe tolerances as per DIN (see sheet PB 27) Handbook Radial Fans / Chapter 2 - REITZ List 2010 TA 2

3 Coents on sound tables Consider the noise of the corresponding drive motor. Acoustic parameter duct noise (see sheet ST 3) The bearing noise is already included in the calculation for the strutural designs K und R, which are fitted with shafts and antifriction bearings. Rounding-off the values to integral numbers will invariably lead to differences in further calculation runs. General coents or or ΔL KA = correction value for A-weighting housing or fan radiation noise with fan ducted (s. sheet ST 4) The DIN tolerances must always be observed. For more information see chapter Acoustic technology ST and pages PB 27and 28. All values refer to free-field conditions. As such they are subject to local influences such as sound level addition, reflection, external bacround noises, system components, ducts, etc. sound pressure level on measuring surface with fan ducted at free-field conditions (see sheet ST 5) free inlet and/or free discharge noise referred to a distance of 1m from the hemispherical radius of the inlet and/or discharge Handbook Radial Fans / Chapter 2 - REITZ List 2010 TA 3
