Our R&D department combines expertise within all sectors of fan technology with highly efficient simulation tools such as CFD (Computational Fluid Dynamics) for flow visualisation and FEM (Finite-Element-Method) to calculate the structure-mechanical characteristics, as well as test ducts and -chambers according to international standard ISO 5801, equipped with the latest measuring technology in order to determine the aerodynamic and aeroacoustic characteristics. We take care of you, wherever you are in the world, with our comprehensive power service package beginning at the moment of...

Project planning advice Theoretical principles Sound pressure Sound pressure waves are small pressure fluctuations that are masked by the ambient pressure. Due to the fact that the sound pressure in the normal pressure unit Pa exceeds several powers of 10, it is usually stated as the sound pressure level in a logarithmic form in the unit decibel [dB]: (1) p2 Lp = 10 ⋅ lg eff p2 o A sound pressure level of e.g. 8 dB therefore corresponds to 108/10 times the lower hearing threshold. This correlation is shown by the examples in Table 1 Table 1: Correlation between the sound pressure and sound...

Project planning advice The enveloping surface unit is determined in (6) as follows: (6) A LS = 10 ⋅ lg mit A0 = 1m 2 A0 The k octave bands can be summarised to a total sound power level LW, tot by means of logarithmic addition for all mean frequencies: (7) LW ,i k LW,ges = 10 ⋅ lg ∑ 10 10 i =1 A-weighting The A-weighting is a relativisation that takes into account the characteristics of the human ear (unit dB(A)). To determine an A-weighted octave spectrum, the level corrections shown in Table 2 are added to the non-weighted spectrum: (8) Comments To calculate the sum of several sound...

Project planning advice Explosion protection Types of protection The type of protection shows the technical action taken to ensure the machine cannot act as an ignition source. Table 5 shows what action can be taken so that nonelectrical components can be used in explosion-protection areas acc. to EN 13463-1 ff (non-electric). Fans may only be used in areas in which there may be explosive media if they have been manufactured in compliance with the Directive 94/9/EC. The principles of this Directive are shown below. Theoretical principles Apart from the CE ( ) and the so-called ATEX symbol (...

Project planning advice The temperature classes are selected like the classification of the explosion protection types depending on the material used and are also stated in the Directive 94/9/ EC or corresponding tables. Identification in dusty atmosphere When fans are used in a dusty atmosphere the identification has to be changed. The explosion protection group is not used anymore. The temperature class is replaced by the maximum surface temperature. Similarity laws This section looks at the similarity laws that serve the conversion of the measuring data for changed operating conditions....

Project planning advice Systemcharacteristic Performance curve Operating point Radian Angles can either be stated in radians (angle in relation to p ) or in degrees.180° degree correspond to a radian of p . Important radians are shown inTable 9. Table 9: Conversion radian and degrees qv [m3/h] Figure 7: Operating point as the intersection of the system and performance curves Ignored or inadequately considered influences that change the system pressure loss and therefore change the flow behaviour lead to a change in the system characteristic and therefore also shift the operating point....

Blade angle Performance curve representation: 104 102 According to ISO 5801, the total pressure increase of the fan with pressure side duct 2000 connection (L,min ≥ 2,5 x DN fan) corresponds to the effective pressure of the fan. The effective pressure is the pressure, which is pressure loss of the system. available to overcome the X *If motor excess length is > 0, a duct extension (Z11) is required to assemble accessories Z07, Z20.
