Technical Details
1.1 Design
Figure 1: Operating point of the ventilator
Elektror low pressure blowers of the ND range are radial ventilators with impellers made from galvanized sheet steel, the blades of which are curved into direction of rotation. They are
directly driven by asynchronous squirrel cage motors of the
company´s own make, especially adapted to the blower requirements and amply dimensioned.

The attractively shaped, stream-line aluminium-cast housings
as well as the dynamically balanced impellers ensure vibrationfree operation at low noise levels.

Operating point
Pressure difference R
The solid design of the Elektror low pressure blowers is basic
for long-life operation and low operating cost.
All drive motors are manufactured to enclosure IP 54 and in
accordance with VDE 0530 (IEC 34-1). As a standard the
motors are laid out for a voltage of 230/400 V or 400 V g at
50 Hz mains frequency three-phase AC and for 230 V 50 Hz
single-phase AC in accordance with IEC 38. On demand the
motors for 60 Hz. mains frequency can also be supplied to
IEC 38.

1.3 Noise characteristics
1.2 Performance
The noise caused by a ventilator ensues from flow processes
and vortices inside the impeller and the housing and is determined by
Ventilators are flow-generating appliances for conveying air and
other gases. As for the radial blowers, the conveyed medium is
drawn in axially, accelerated radially by the rotation of the
impeller and expelled tangentially. The resistance to the
discharged air (by duct work, pipes, filters and other parts of
the installed system) has to be compensated by the generated
excess pressure of the ventilator. The ability of the ventilator to
generate pressure diminishes with increasing flow volume
(volumetric flow rate). This operating behaviour depends on
the characteristic curves of pressure difference and volumetric
flow rate (specific ventilator curves).
a) the basic design of the ventilator (axial, radial, construction
principle of impeller).
b) the size of the ventilator in relation to the requested pressure differentials and flow volumes.
c) the operating point of the ventilator, i.e. in which range of the
characteristic curve the ventilator will be operated.
d) the rotational speed which can be reduced by the variable
speed control for the Elektror low pressure blowers.
The resistance of air-conditioning systems (system resistance)
varies (in most cases) by the square of the changing volumetric flow rate, i.e.: If the flow volume is to be doubled, four times
the system’s resistance has to be compensated. The resulting
characteristic curves are termed resistance parabolas or characteristic system curves.
Noise emissions are not constant over the whole performance
range.
Blower housing and impeller are especially designed for the
required flow conditions, whereby the noise generation
depends mainly on the required flow volume and pressure difference as well as on the correct selection of the ventilator.
The operating point of the ventilator is determined by the
intersection of the two characteristic curves.
For evaluation of the noise respectively of the sound pressure
level the measuring unit dB(A) is used. The letter “A” in the
measuring unit refers to the standardized frequency evaluation
which takes into account the highly frequency-dependent and
subjective perception of noise levels: High frequencies ar perceived as more unpleasant than lower ones.
As far as the system resistance cannot exactly be calculated
mathematically, recourse should be taken to experiment or
empiric values. With increasing system resistance the flow
volume decreases and the power consumption drops.
The maximum volumetric flow rate of the ventilator is determined by the intersection of the characteristic curves gPt and Pd2
(see figure 1).
If a number of sound sources of equal volume are evaluated
together, the sound pressure level will increase for instance by
2 dB for two appliances, by 5 dB for three, 6 dB for four, and
7 dB for five. A change by 10 dB eventually means double or
half the noise level perception. With increasing distance from a
sound source noise emissions grow weaker; doubling the
distance may result in a noise level reduction of up to 5 dB.

1.4 Performance curves
Influence of density
The indicated performance curves of the total pressure head
gPt and of the
. static pressure gPst as function of the volumetric flow rate V have been ascertained by measuring tests and
are partially above the values specified in the technical tables.
The measurements were performed without protective wire
mesh guard on the intake side.
Total pressure difference, dynamic pressure, static pressure
and power consumption of the blower change in proportion to
the density of the conveyed medium and are to be considered
when selecting a blower (figure 3).
All measurements were taken on a pipe test bed to DIN 24 163
with throttling on the discharge side, and based on an air density of 1,2 kg/m3.
ρ2 = ρ1 273 + q1
273 + q2
Alterations in density due to influence of temperature are calculated as follows:
The sound pressure levels LA have been ascertained on the
intake side at a distance of 1 m from the inlet with the blowers
connected on the discharge side to the pipe test bed.
q = temperature of conveyed medium [°C]
ρ = air density [kg/m3]
Figure 3: Influence of density of conveyed medium
ρ = 1,4 kg/m3
ρ = 1,2 kg/m3 catalogue data
1.5 Blower selection
Applicable pressure difference
If the required pressure difference and the desired air volume
have been established either by testing or by calculation, it
should be verified how much of the total pressure rise of the
blower can be used as static pressure difference.
pt
Total pressure rise g pt R
Increasing the cross-section of the discharge duct work by gradual enlargement (difusor) will delay the volume flow, and the
dynamic pressure will be converted to static pressure. The
recovered pressure may be included to overcome the system
resistance, or allow for the use of a smaller blower at the same
volumetric flow rate (see performance curve 2, figure2). The
efficiency of difusors depends on the opening angle. Pressure
gains by difusors on the intake side are unimportant and may
be neglected.
▼
Required power of blower P R
▼
If the duct work connected to the discharge side has the same
coss-section as the discharge port of the blower, or if the blower discharges freely, the dynamic pressure part Pd2 must be
considered a loss. The remaining part of the total pressure rise
is then available as applicable static pressure difference gPst.

1.6 Standard and special designs
elektror-mail@ya.ru
Model range RS
2-step version for three phase and single phase a.c. with
installed temperature controller as motor protection for which the
speed-control can be effected via step switch.
Standard range
Application is useful wherever unchanging operating conditions
prevail or pressure relations vary slighty only and a constant
flow volume is required.
All units of the standard range correspond to the safety requirements of the Supervisory Board of the Chemical Industry and
have been tested and certified.
Speed controlled blowers of the range RVE and RS cannot be
delivered with temperature barrier. Maximum temperature of the
conveyed medium is 40° C.
Model range FU
All standard blowers can be speed-controlled via frequency
converter. The motors are equipped with PTC thermistor sensors
for trip device and with a reinforced barrier.
Twin blowers
Driven by one common motor and attached to both sides of it,
two blowers are assembled into one single unit as a special construction design.
The advantage of these blowers is the high flow volume with
small dimensional layout.
As the twin blowers possess two discharge connectors, the volumetric flow rates may be used together or separately for the respective applications.
The technical data are identical with those of the standard
blowers. Speed control form 0 to 50 Hz maximum.
Compact blowers
The design offers very compact dimensions by incorporating the
motor into the blower housing respectively into the impeller at
comparatively favourable characteristic curves.
The motor needs no additional cooling as it is located in the air
flow. To guarantee sufficient cooling of the motor the blower cannot be operated fully throttled – neither on the discharged side
nor on the intake side.
In case of high air pollution a filter must be fitted on the intake
side to avoid contamination of motor and impeller.
Speed controlled blowers
They are to be used wherever for process-inherent reasons the
change of volumetric flow is needed.
Model range RVE
Special blowers
By means of a generalised phase control, which is housed in
the terminal box of the motor in a space-saving way, any
random operating point can be continuously adjusted within a
range of 20 to 100 % within the characteristic field by means of
the potentiometer supplied. A two-stage setting is possible as
well.
For special applications the standard blowers can be adapted to
existing requirements by special equipment whereat also customermade solutions can be found.
In case of speed reduction, energy is saved effectively in the
partial load range, and the noise generation is reduced distinctly.
Alternating current motors speed adjustable by voltage reduction
from own production are used as drives especially adapted
to the ventilator. The motors have been equipped with PTC
thermistors so that a thermistor-type motor protection is ensured
in combination with the generalised phase control.
Thus, the user has a wide range of applications with ideal
problem solution and the following advantages:
● Continuously adjustable from 20 to 100 %
● Absolutely free from maintenance
● Considerable reduction of the sound emission in case of
speed reduction

Conveyed medium and ambient temperatures
Voltage and frequency
The permitted ambient temperature (cooling air temperature) of
the drive motors is -30 °C to + 40 °C. As a standard the motors
are made to thermal class B in accordance with VDE 0530
(IEC 34-1), the speed-controlled version to thermal class F.
The motors of the standard version are made for a voltage of
230/400 V ( g / V ) or 400 V (g) three phase a.c. at 50 Hz
mains frequency and for 230 V single phase a.c. in accordance
with IEC 38. On demand the motors for 60 Hz mains frequency
can also be supplied to IEC 38.
An increase in the permitted ambient temperature above 40 °C
is possible by using suitable insulation materials. This should
be discussed with the manufacturer, however.
Special voltage and special frequency as well as motors for
voltage change-over or multi-range voltage can be supplied on
demand.
The permitted temperature of the conveyed medium for the
standard range is from -30 °C to +80 °C.
Permitted maximum voltage for three phase a.c. is 690 V and
277 V for single phase a.c.
The fitting of a temperature barrier to the standard units between blower and motor allow for conveyed medium temperatures of up to 80 °C.
An alteration of the mains frequency leads to a change of the
motor speed (r.p.m.) and of the impeller whereby the total pressure rise, the flow volume and the power consumption change
as follows:
Sealing
Higher enclosure to IP 55 and IP 65 as well as tropical and
moisture-proof insulation are possible for all motors.
n2
If the blowers have to be gas- and air-tight to a certain extent,
a rotary PTFE shaft seal can be fitted into the shaft bore. Further sealing options of the blower parts are flat gaskets or elestic sealants.
By choice of material (cast and sheet aluminium) the standard
blowers are already nearly corrosion-resistant.
For special applications, the blowers may be painted or coated
with plastic resin. the impellers can be manufactured from alloy
1.4301.
The standard blowers are equipped with two-pole motors.
Change-pole motors 4/2 or 4-pole motors, can be supplied on
demand.
An alteration of the number of revolutions of the blower will
change the total pressure rise, the flow volume and the power
comsumption as follows:

1.7 Directions for operation and
maintenance
Elektror low pressure blowers are equipped with sealed
grooved ball bearings which do not need relubrication. The
grease filling is sufficient for their operational life.
Inspection and eventual cleaning should be carried out at
regular intervals with special attention to the safety instructions. Soiled and worn impellers cause an unbalance which
may result in bearing failure.
Safety of operation as well as the indicated performance data
are no longer guaranteed.
Conveying of solids is not permitted.
If the conveyed medium contains solid particles or other pollutions, the have to be removed before entering the blower by a
filter on the intake side. Permeability of the filter must be ensured.
Conveying of explosive mixtures is not permitted.
Blower with open discharge or intake ports have to be equipped with a contact safety device in accordance with DIN EN
294 as far as such a device has not already been fitted in the
factory.
The units have to be installed in weather-protected places and
must not be exposed to strain by vibrations, shocks and percussions.
Units above 3 kW must be started in ( g / V ) configuration.
The instructions for installation and operation supplied with the
blower unit have strictly to be adhered to.

Fine filter
intake side
Layout and dimensions of Elektror fine filters are adapted to the maximum flow
volume of the respective blowers and have a very small pressure loss therefore.
The filter surface has been selected for an air resistance of 50 Pa at an air flow
velocity of q,5 m/s.
The insert filter tissue of synthetic fibres provides a high filtration efficiency
of about 99 %.
Dirty filters may be cleaned with compressed air or by washing with a light
soap lye.
All steel parts are zinc-galvanisied to provide high corrosion protection
Caution
Clogged and dirty filters reduce the blower performance significantly.
Cleaning of the filters in regular intervals is essential.
