Nicotra-Gebhardt stands for:
• Maximised flexibility and minimised design effort for customers, because all radial fan casings have identical dimensions – no matter what kind of impeller geometry
• Top product quality and shorter delivery times – thanks to
state-of-the-art production technology
• Energy efficiency through comprehensive system knowhow

A strong provider for many optimal solutions:
The Nicotra-Gebhardt portfolio
When it comes to radial fans, we are the first people you should talk to. From belt-driven radial fans to
plugfans, it’s all there in our product portfolio. We offer the largest, most comprehensive range of products
in this area – and of course the matching services.

When everything fits:
100% compatible product series
To us, perfection in our product portfolio means that all product series in the area of encased radial fans
are attuned to one another and are 100% compatible in their dimensions. How did we do it? By using an
identical design for the connection dimensions of every fan size in our newly developed series ADH-E and
RDH-E and carefully coordinating our options and accessories. In this way, we have standardised and harmonised our product portfolio in all relevant areas.
Well designed, easy to install, economical –
The compact base frame from Nicotra-Gebhardt
A system that saves space, time, and money – in an air handling unit or any other application: our compact
base frame offers decisive advantages:
• The frame lengths have been optimised and
adjusted for the casing position and motor
installation height to achieve the smallest possible overall height and length
• Exact, optimised coordination of all components,
all the way through to installation, adjustment
and testing
• Suitable for all fans of the series ADH-E0, RDHE0 and RZR-11 up to size 0500
Greater system efficiency

proSELECTA II
proSELECTA II is a technical selection program that allows you to configure your own individually designed fan. It provides you with the opportunity to choose from the entire range of fan types and their
associated options.
Simple and reliable selection
The result from proSELECTA II is the provision of all the
technical data for your fan, including sound level data, dimension specifications and accessories. Apart from that, as a registered user, your purchase prices are provided. Additionally
fully dimensioned drawings in dxf format are available, which
can be downloaded and transferred straight into your CAD
system.
So that you can be sure
Models and options that are technically not permissible, are automatically excluded in proSELECTA II. So
there is no chance that you will configure a “wrong” device option.
What else is important to you
During the fan selection process, you can choose any of the standardised ATEX options.
Free registration and many advantages
You can register as a proSELECTA II user with us, which enables us to offer you faster order processing.
What this means for you is:
• The complete configuration of your fan with its
associated system accessories and belt drive
layout.
• The possibility to produce fans that operate via
a frequency inverter.

The RLMseries!
Nicotra-Gebhardt has successfully further improved its free running impeller
line (plug fans).
By optimising the impeller geometry a significant reduction in noise level
up to -6 dB was achieved, without affecting the aerodynamic performance
characteristics in any way.
In stating the performance data we have kept to the representation of the
static pressure and staticimpeller efficiency. These values correspond to the
practical figures in application case.
The fans can simply be selected via the fan selection program
proSELECTA II.
All technical specifications, dimensions and performance curves are available for you.
Top quality for performance and a long service life!

All fittings and accessories must be ordered separately.
Please take the technical data and dimensions from the corresponding page of the
catalogue.
Flanges and Flexible Connections
Flanges and nozzles with elastic spacer piece are available for the inlet side.
The dimensions must be taken from the fan dimension diagram.
Inlet guard
The fans are designed for installation in equipment and as standard are not equipped
with protective guards.
They should not be put into operation before all protective devices are fitted
and connected!
Protective measures must be carried out as set out in DIN EN ISO 12 100 "Safety of
machinery - Basic concepts, general principles for design".
If the application of the fan allows free access to the inlet and discharge apertures,
safety devices must be put in place on the fan in accordance with DIN EN 294!
Suitable safety guards are available as an optional extra.
Anti Vibration Spring Diffusers
50
AV mounts are designed to prevent noise and vibrations being transmitted through
the base of the fan.
AV mounts should be mounted beneath the fan base frame so the weight and spring
deflections are evenly distributed. They should not be mounted symmetrically around
the centre of gravity of the system when idle, because a counter force is induced into
the system by the pressure created by the working fan.

It is difficult for the manufacturer to establish the position of the AV mounts to suit all
types of application.
Vibration and noise insulation can also be improved by ensuring that the fan is connected to its external environment by a flexible coupling.
Available AV mounts for different fan types, see Technical Data.
The AVM-mounts are supplied with the suitable mounting material for the base frame
(CC- or U-Profiles).

When fans are built in a plenum, it is required to measure the differential pressure
between the static pressure in the plenum on the suction side and the pressure at the
inlet cone.
To ensure that the static pressure to be measured at the inlet nozzle is not distorted
by dynamic velocities, it is recommended to attach a ring of points on the wall as
shown in the following diagram.
If the differential pressure is conducted via a pressure sensor, the signal can also be
used for controlling.

Frequency inverter
Design
Frequency inverter with variable output voltage and frequency, specially designed for
the operation of centrifugal fans with induption motors. Due to the use of modern power semiconductors it is possible to achieve a speed of revolution with high efficiency.
Switching frequencies up to 16kHz can be set with all types. If the highest switching
frequencies are required (for example for reasons of noise reduction), the maximum
output current is decreased, in which case the performance category should be
specially checked.
The overall package includes the frequency inverter, filter for class B (for residential and commercialuses) as well as a control unit.
General Performance characteristics
Motor protection feature for motors with thermistor temperature sensors, adjustable
accelaration and deaccelaration ramps, minimum and maximum rotation speeds,
fixed rotation speeds, trapping switch during operation, programmable inputs and
PI-controller (MM420 and MM430 only), RS 485 serial interface as well as a detailed
operating instructions. Caution about combination with isolators (ESH)! Special EMCaction can be necessary, furthermore do not switch during operation, overvoltages
can destroy the switch and the motor-winding.
Performance range G110 1AC 230V (for single-phase AC supply)
0.25 to 2.2 kW rated motor power, 200 to 240V 10% single-phase AC, 47 to 63Hz,
three-phase current output 3 × 230V AC, protection class IP 20.
Permitted ambient temperature during operation: -10C to +40C.
Performance range MM420 3AC 400V (for three-phase AC supply)
0.55 to 11kW rated motor power, 380 to 480V 10% three-phase AC, 47 to 63Hz,
three-phase current output 3 × 400V AC, protection class IP 20. Permitted ambient
temperature during operation: -10C to +50C. The interference suppression filter required to comply with the EMC basic interference suppression standard EN 50081-1
(residential and commercial uses) is integrated into the package as substructure
option. Power choke to comply with EN 61000-3-2 as additional component.
Observe performance reduction when using highclock frequencies!
Performance range MM430 3AC 400V
(for three-phase AC supply)
15 to 250kW rated motor power, 380 to 480V 10% three-phase AC, 47 to 63Hz,
three-phase current output 3 x 400V AC, protection class IP 20.
Permitted ambient temperature during operation: -10 C to +50C. The interference
suppression filter required to comply with the EMC basic interference suppression
standard EN 50081-1 (industrial applications) is partially integrated. In order to attain
EMC requirements Class B a frequency inverter without filter should be selected.
The appropriate EMC-B filter is then required as an additional component.
Observe performance reduction when using highclock frequencies!
The indicated ratings of the units are made for a quick selection. The exact dedication
of an inverter in this catalogue is made by taking into account of the max. admitted
current at a pulse frequency of 4kHz. It is important to know that at higher pulse
frequencies the supplied current of the inverter will be decreasing, with the possible
consequences of having to select a larger inverter unit. Also longer feed lines or additional radio frequency filters may lead to the choice of a larger inverter size.
The selected frequency inverters (G110 und MM420) are units contains the
frequency inverter (as shown in the following tables) with the matchinginterference
suspression filter (Class B) and a control panel. A further component is the line
choke which is available as an accessorie. For more information the available
frequency inverters are shown in the following tables.

Motor protection unit
Motor protection unit for three-phase current motors (standard motors) without thermal contacts.
Design
Plastic casing in protection class IP 55, permissible ambient temperature +40 C, 40
up to 60 Hz, frontal operation, for wall mounting. Motor protection unit for singlespeed, non- variable speed three-phase current motors without thermal contacts.
Function
The motor protection units must be adjusted on site to the trigger current. If the
preset trigger current is exceeded, the device disconnects the motor from the mains
supply via a thermal overload release. Pressing the “on key” causes the unit to turn on
again.
All motor protection units EUM 33 are also suitable for the protection of EExe-motors
(PTB-Prüfung Gesch-Nr. 3.35/386.3060). They must however be mounted outside of
explosion endangered areas, since they are not themselves designed with explosion
protection.

RLM - Correction of design for installation in an enclosure
The installation of the fan in an enclosure leads to a reduction of pressure and flow
compared to the stated performance characteristics.
The following diagram shows the speed correction factor fn as a function of the size
of the enclosure when the box sections are quadratic and the fan is laid out symmetrically (inflow and outflow according to the diagram).
A= B×H
When fans with flange motors are used in box casings, the speed and power stated
in the performance map must be corrected with the factor from the diagram above
according to the following equations:
The calculated speed must not exceed the admissible maximum speed of the fan.

RLM - Measurement of performance
The performance curves of the fans are determined at the plenum test rig according
to ISO 5801 ”Fans,
Measurement of performance, Standard test rig”. The curves show a free discharge
pressure rise psF as a function of the volume flow rate qv in double logarithmic grid
distribution.
The choke lines (resistance parables) appear as straight lines.
The free discharge pressure rise shown here is the usable static pressure rise which is
available to cover the system losses.
The dynamic pressure at the outlet is not included in the stated increase of pressure.
The efficiencies stated in the performance maps are static efficiencies, i. e. they are
based on the static increases of pressure without dynamic pressure.
The data apply to the reference densities stated in the performance maps. Increase in
pressure and power vary proportionally with the density.
The performance data of the RLM centrifugal fans are classified in precision class 1
according to DIN
24166 ”Fans, technical delivery conditions”.
RLM - System efficiency
se = F × M × sr
qV × psF
Pe =—

RLM - Sounds
LWA5 = LWA8 – 4 dB
The system efficiency is the product of the efficiencies of the frequency inverter, motor
and impeller.
The electric power of the fan taken from the mains can be determined with the system efficiency.
Sound measurement and analysis are carried out in accordance with DIN 45 635-38
”Sound measurement at machines; fans”.
In the performance maps the A sound power level LWA8 is stated as emission parameter for the discharge side.
The value for the inlet side LWA5 can be calculated with the given conversion tables.
RLM - Sound protection
The unvalued sound power levels in the octave band corrections are important for
precise calculations in
order to define sound protection measures.
They can be defined with the following formulas and the values of the tables below
the fan curves of each size.
LWfc8 = LWA8 + LWrel8
LWfc5 = LWA5 + LWrel5
RLM - Relative sound power level
N
fD = —
10
The stated relative levels were averaged within a performance characteristics range of
0.8 up to 1.35 qvopt.
At operating points outside this range higher deviations from the stated values can
be expected, in particular at low frequencies.
In isolated cases, the sound power levels at the octave bands can reach in the
frequency range of the revolving tone values somewhat higher than those calculated
with the table.
It must be noted that room acoustics, natural frequencies, reflections, installation in
equipment, etc. can influence the sound at a particular location.

RLM - Introduction
The fans in this catalogue are designed for installation in equipment. Due to their
special shape, the impellers represent the ultimate in technology and economy achievable today.
The lines are classified according to the standard line R 20 and practically cover the
suitable applications for fans without casing.
They are suitable for handling air and other nonaggressive gases.
RLM - Temperatures
The permitted flow medium temperature is between -20 C and +40 C.
The maximum ambient temperature at the motor is +40 C.
RLM - Impeller
All impellers are balanced statically and dynamically according to DIN ISO 1940,
specification G 2.5, based on the maximum speed from size 4550.
The line 50 impellers with backward curved blades made of sheet steel, are welded
and coated.
RLM - Direction of rotation
intravent centrifugal fans without casing are supplied with the direction of rotation RD
(righthand turning) as standard.
The direction of rotation is determined by the viewing direction of the bearing unit side
(drive side).
RLM - Inlet cones
The inlet cones are aerodynamically shaped to provide an even distribution of air over
the full width of the impeller. In modularly designed fans the gap and overlap of the
impeller is optimally adjusted and fixed permanently.
RLM - Motors
Standard motors of wellknown brand makes, protective system IP55, heat class F,
are used. During commissioning and maintenance the detailed instructions provided
by the motor manufacturer (type plate/motor operating instructions) must be followed,
this also applies to the motor protection devices required onsite. The motors are
equipped with PTC resistors/temperature sensors as standard. Motors with integrated frequency inverters may be supplied on request.
RLM - Speed variation
A suitable speed variation system is required for the optimum adjustment of the
desired operating point.
Gebhardt frequency inverters are perfectly tuned for the operation of RLM plug-fans
with flange motors.
RLM - Electric connection
The centrifugal fans RLM are delivered ready for installation.
The motor terminal box can be accessed easily.
Electric installation must be carried out according to the applicable provisions in
compliance with local regulations. A terminal board circuit diagram showing correct
connection is enclosed with every motor.
Updated circuit diagrams are also available online at www.gebhardt.de / Downloads.
In case of operation with frequency inverters, always follow the respective operating
instructions!

RLM - Explosion protection according to ATEX
Fans for operation in ex-hazardous areas have to conform to the EU Directive 94/9/
EC (ATEX 95). Units of
the group II (all applications except mining) are classified corresponding to their
degree of safety into categories 1, 2 and 3. A further distinction is made according to
their use in G (gas, vapour) or D (dust) environment. Harmonised European standards
and national guidelines are to be observed.
The centrifugal fans RLM comply with the requirements of ATEX Directive 94/9/
EG due to their structuralsafety and reliable construction in accordance with
DIN EN 13463-1 and -5, pr EN 14986:2004.Allocation is to device group II, category 2G, explosion group IIB, temperature class T4.
ATEX category II 2G IIB T4
Fans in this category are designed to be used in areas where there is a risk of an
explosive atmosphere consisting of a mixture of air and gases, vapours or mist
existing occasionally. The device-related explosion prevention measures for this
category must provide the required degree of safety even where there are frequent
device malfunctions or error conditions which must be taken into account as a matter
of course (foreseeable malfunctions). For the operation of fans in areas subject to a
risk of explosion the relevant provisions and local regulations as well as corresponding
directives (ATEX 95, 137) for both the manufacturer and operator must be observed.
