TLT standard fan production plant at Bad Hersfeld 

Our Bad Hersfeld facility has a history 

going back to 1874, when Benno 

Schilde and August Büttner founded 

their factories here. 

The “exhausters” traditionally made 

of cast iron could be built much lighter 

and cheaper through the use of steel 

sheet. 

At Büttner the focus was initially on 

blowers for tubular boilers and dryers, 

then shifted to heavy-duty industrial 

fans as required specifically in power 

plant de-dusting applications. Schilde, 

meanwhile, stepped up its research 

and development of light-duty 

ventilating fans and medium-duty industrial 

blowers. Numerous patents 

and registered designs testify to a 

steady flow of engineering breakthroughs. 

With the erection of its series 

production facility at Bad Hersfeld, 

dedicated mainly to the cost-effective 

production of roof fans, the 

Babcock-BSH Group gained a leading 

market position both in Germany 

and abroad. The Turbo-Lufttechnik 

GmbH (TLT) – Bad Hersfeld site - was 

newly established in June 1995, now 

integrating Babcock-BSH’s Air and 

Thermal Engineering division. 

The “TLT-Turbo GmbH”, newly established 

in March 2003 as a company 

AXIAL FLOW FANS 

in their own rights, belongs to AG 

Kühnle, Kopp & Kausch, Frankenthal. 

TLT now is one of the world’s leading 

fan manufacturers and our competence 

is expressed in mature and 

very economical products. Our two 

R&D centres at Zweibrücken and Bad 

Hersfeld guarantee a continuing process 

of always adapting all TLT products 

to the latest demands of the 

market.

use at 200°C / 300°C / 400°C or 

600°C (120 minutes) 

● two-stage axial fans (in series) 

for use in closed car parks and 

for elevated pressure ranges, 

also as smoke exhaust fans for 

200°C / 300°C or 600°C /120 minutes 

operation. 

All our fan series are tested to EN 

12101 - Part 3 specifications by the 

Technical University of Munich and 

hold a General Construction Supervision 

Approval issued by the German 

Institute of Construction Engineering 

(DIBt), Berlin as well as 

CE-certificates.

AXN SERIES with outlet 

Guide Vanes 

Technical Description 

High output and broad operationg 

poing adaptability are key features of 

all fans of this series. 

■ 21 available design sizes with casing 

diameters from 250 to 2500 

mm 

■ Two basic designs for direct drive 

(M) or belt drive (R). 

■ From optimum pressure coefficiets 

this series is equipped with outlet 

guide vanes. 

■ impeller blades are steplessly 

pitch-adjustable without having to 

remove the impeller from the unit. 

Post-installation adjustments to 

specific operating points within the 

motor output range can thus be easily 

made. 

■ Impellers can be supplied with 12, 

9, 8, 6 or 4 blades (important particularly 

for direct-driven fans). 

■ The impeller material is cast solumin, 

with the exception of the clamping 

strap which consists fo AlMg 

3F-2. A high weather and seawater 

resistance is thus ensured. 

■ On R1 and R2 (belt driven) types, 

an additional operatiin point matching 

feature is available via the 

“stepless“ impeller rpm adjustment 

which can be achieved by changing 

the belt transmission ratio. 

■ High pressure coefficients permit 

low tip speeds for minimum operating 

noise. 

■ Efficiencies up to 82% 

■ Tip speeds up to 85 m/s 

■ Direct-driven fans are normally 

supplied as airflow direction “D“ 

(outlet over motor) designs. In special 

cases, airflow direction “S“ 

Unless special precautions are 

taken, these axial-flow fans are not 

suitable for outdoor installation (enquiries 

to be directed to our headquarters).

Why provide diffusers? 

Axial-flow fans generate a total pressure 

increase (�pt) which comprises 

a static pressure portion (ps) and a 

dynamic one (pd). The impeller of an 

axial-flow fan consists of blades and 

hub located in the airflow. The result 

is a circular flow of considerable velocity. 

This high flow velocity (c) gives 

rise to a high dynamic pressure. 

When an axial-flow fan is allowed to 

discharge freely into a room, as is 

often the case, the entire dynamic

MAIN DIFFUSER DIMENSIONS 

pressure (related to the annular 

cross section) ceases to be effective 

and must be considered a loss. A diffuser 

will reduce the outlet velocity 

substantially and thereby prevent 

much of this dynamic pressure loss. 

In other words, to achieve an otherwise 

identical static pressure difference, 

the total pressure increase to 

be generated can be reduced, and 

so can be the output of the fan motor. 

Another benefit lies in the increased 

outlet surface area, which results in a

Complimentary to our AXN 12/56 series 

(with outlet guide vanes) we supply specially 

developed round silencers in 13 sizes. 

These units substantially reduce the 

sound level. 

They are easily fitted on the fan inlet or outlet 

side, without any additional intermediateelements. 

The silencer housing consists of Sendzimir 

galvanized sheet steel. 

Mounting nuts are provided internally on 

the connecting face sides (hole pattern as 

per DIN 24154 – Series 3). 

The interspace between the exterior barrel 

and the interior sleeve (made of galvanized 

perforated sheet metal) as well as 

the interior core are filled with a non-combustible 

acoustic damping material. 

(The sketch shows an axial-flow fan 

with extension casing and one round 

silencer each on its inlet and outlet 

sides).

Acoustic level

directly from the characteristic 

data sheets for each operating point. 

Starting from this value, the A-weighted 

acoustic power level LWA and the 

1. Acousting power level emitted into the duct 

The level of acoustic power an axial-flow fan emits into the 

ducting is used for calculating the sound power characteristics 

of downstream systems, e.g., silencers. 

The levels are calculated as follows: 

Lwvent. [dB] = total acoustic power emitted by the fan, 

(please see respective characteristic curve 

sheets) 

LwA vent. [dB] = A-weighted acoustic power level, according 

to the equation 

Lw A vent. 

= Lw vent. – portion 1.1 [dB] 

Lw rel vent. [dB]= relative acoustic power level as expressed 

by the equation 

Lw rel vent. 


2. Acoustic power emitted from the fan inlet or outlet 

opening 

To determine the sound levels at a given installation site, 

it is usually necessary to know the level of acoustic power 

emitted from the fan’s inlet or outlet opening. The adjacent 

tables are based on the outlet reflection pattern assumed 

in VDI 2081, Case 2.

Application example for 

axial-flow fans 

The volume flow measuring system 

determines the operating volume flow 

of an axial fan installed in an air-handling 

installation. The system greatly 

facilitates the determination of fan volume 

flow. As a result, the cost and effort 

required for in-duct measurements 

on the system side, as often 

carried out during commissioning, 

can be significantly reduced. Moreover, 

adjustments are faster and easier 

to carry out. 

The measuring accuracy of the volume-flow 

measuring system is approx. 

± 5%. 

Description of the measuring 

system 

The volume flow measuring system is 

firmly mounted on the fan to determine 

the volume flow in its installed condition. 

The reading is obtained by a 

simple differential-pressure measurement 

between the sockets of the 

pressure measuring lines connected 

to the measuring system. The calibration 

curve is prepared individually, taking 

into account fan-specific parameters. 

Key influencing variables include 

fan type, inlet density, rpm and 

fan design size. Being established individually 

with reference to the above 

parameters, the calibration curve is 

not transferable to other fan types 

Options 

Adirect automatic volume flow measurement 

can be implemented by 

means of root-extracting differential 

pressure transducers or suitable 

electronic evaluation units. The following 

equation may be used for this 

purpose:

AND AXIAL FLOW FANS 

and sizes. At fan operating speeds 

deviating from the rated rpm level, 

major inaccuracies will be obtained, 

especially when the fan is running at 

slower speeds. 

The measuring system consists of an 

additional casing extension made of 

sheet steel, pre-installed measuring 

lines for the pressure measurement, 

and a sheet aluminium hub body attached 

to, and rotating with, the fan impeller. 

The pressure measurement 

ring line consists of plastic hose as 

employed in pneumatic applications, 

as well as brass screw-in adapters. 

The four measuring points, spaced 

evenly over the circumference, are 

connected into a ring line by means of 

T-fittings. The connection to a pressure 

measuring instrument is likewise 

made via a T-fitting. 

Technical description 

The calibration curves can be computed 

for flow medium throughput conditions 

as habitually employed in ventilation 

technology, and apply to air only. 

The measuring system is standardized 

for AXN series fans in the 315 

to 2000 size range. It is recommended 

to use the volume flow measuring 

device only at blade angles equal to, 

or exceeding, 10 degrees so as to to 

maximize the accuracy of the reading. 

At blade angles below 10 deg., 

the magnitude of the differential pressure 

indication will not suffice for an

unambiguous volume flow measurement. 

The accuracy of the system depends 

essentially on its installation 

conditions and on the inlet-side approach 

flow situation. An irregular or 

swirl-impaired inlet airflow will reduce 

the accuracy of the volume flow measuring 

system. The differential pressure 

measurement can be carried out 

with the aid of electronic differential 

pressure sensors or other standard 

commercial transducers, whether 

mechanical or hydrostatic. The measuring 

range of the differential pressure 

instrument should be 0 - 2000 

Pa, at a resolution of 1 Pa. The measuring 

tolerance of the instrument 

employed should be better than ± 2.5 

of the measured value.

Drive motors 

Axial-flow fans of the AXO/AXN type 

are powered by surface-cooled motors 

according to IEC standards. Up 

to motor size 180, standard motors 

with type V1, B14 or B5 flanges are 

used, depending on the mounting position 

(AXO types are always supplied 

with B3 flanges). From motor size 200 

upwards, standard B3, V5 or V6 footmounted 

units are selected, again depending 

on the mounting position. 

These motors meet VDE 0530 specifications 

for electrical machinery, protection 

class IP 44, insulation class B, 

fitted with noise-tested antifriction 

bearings. 

Standard versions of these axial-flow 

fans are rated for a maximum operating 

temperature of 70°C since their 

impeller material is not resistant to 

higher thermal loads. 

Motor bearings require periodic regreasing. 

For guidance, the following 

lubrication intervals are given:

ELECTRICAL NOTES 

GENERAL / MOTOR PROTECTION 

In any case, the motor manufacturer's 

detailed instructions must be observed 

(see motor nameplate). Motors 

up to size 200 in standard version 

have no relubrication device, on these 

motors bearing housings must be 

opened to apply new grease. Motors 

of size 225 and upwards have a relubricating 

device with grease valve. 

Single-speed motors can be run on 

230 V or 400 V three-phase a.c. (50 

Hz); pole-changing motors require a 

400 V / 50 Hz three-phase a.c. operating 

voltage. 

Other voltages, frequencies and class 

ratings may be available as special 

versions.

Motor protection 

First of all each power circuit must be 

fused. Fuses, however, can only protect 

switchgear and mains feeders 

against short circuits. They do not 

protect the motor from overload. Due 

to the breakaway starting current, 

which is many times (4 to 6x) the nominal 

current, these fuses must be 

rated higher than the nominal motor 

current would nominally require. To 

protect the motor itself, the following 

options are available: 

027 

1. Thermal overcurrent release 

(bimetal protection switch) 

This current-related motor protection 

device is set to the nominal voltage 

stated on the motor nameplate. In the 

case of an overcurrent it interrupts the 

motor contactor holding circuit. This 

is the most common overload protection 

system adopted for electric motors 

nowadays. 

2. Thermocouples 

In this system, thermostatic circuitbreakers 

are incorporated into the 

motor winding. In the case of an overtemperature 

they open or close a circuit. 

They are wired to the motor terminal 

panel. 

3. Full thermistor protection 

Thermistors are temperature-sensitive 

resistors which change their resistance 

briskly at a given temperature. 

Three such components are incorporated 

into the motor winding. In conjunction 

with a release device they 

provide an effective motor temperature 

monitoring function. 

Electric motors are primarily at risk 

from overcurrents due to overloading 

or phase failure. For this reason, the 

thermal overcurrent release is the 

most widespread motor protection 

system. Thermal cutouts or thermistors 

monitor the winding temperature 

directly. Since the winding may 

overheat not only from excessive electrical 

loads (i.e., overcurrent) but 

also due to a malfunction of the 

motor-cooling or an increase in the 

coolant temperature, these last-mentioned 

devices are also referred to as 

"full protection" systems. They are 

recommended wherever motors are 

at risk from cooling failures or 

overheating of the coolant. Moreover, 

the use of thermocouples or thermistors 

is recommended on motors with 

a very high number of poles where in 

the case of a phase failure, the current 

in the remaining phases will increase 

but slightly.

Hazardous duty 

Hazardous-duty motors, whether of 

the "Ex(e)" increased safety or "(Ex)d" 

explosion-proof type, are supplied for 

400 V three-phase a.c. operation and 

installed for ignition class G1 to G4. 

Please enquire about "(Ex)d" type 

availability. Such "explosion-proof" 

(pressure-containing) motors are required 

in rooms and operating facilities 

in which explosive atmospheres 

are frequently present (refer to VDE 

0165). Whether a location or plant belongs 

to a hazardous-duty category 

according to this regulation must be 

decided by the relevant supervisory 

body, e.g., a trade supervisory authority 

or technical inspectorate. These 

authorities will also determine the applicable 

protection class. (Conditions 

may vary from country to country)

Operation 

Direct on-line starting 

The breakaway torque may reach 150 

– 300% of the nominal torque, depending 

on output and number of poles. 

Starting currents may rise to between 

4 and 6 times the rated current value. 

Star-delta starting 

Here the starting current and torque 

are only about one-third of what they 

would be with direct on-line starting. 

The motor should be close to its nominal 

rpm before the changeover is 

made. 

With high-powered motors, please 

consult with us on fan starting modes 

and start-up times.

Use 

Preferably in applications in which 

the system resistance lies on the 

inlet side, e.g., straightforward air 

extraction or venting systems, process 

equipment, cooling towers, 

condensers, greenhouses, livestock 

stables, and in dryer exhaust service. 

For systems with outlet side resistances, 

these fans should be used 

with caution specifically if such resistances 

are encountered immediately 

downstream of the fan. The swirl 

may cause resistances to increase to 

many times their calculated value. 

Please consult with our engineering 

experts in such cases.

Important design notice: 

Axial-flow fans have a pronounced 

stall range starting on the left of the 

respective curve end. Due to the risk 

of fatigue failure, an axial-flow fan 

must not be operated in stall mode. It 

is therefore important when sizing 

these fans to allow for an appropriate 

safety margin around the stall point. 

The operating point should be located 

on the right-hand (steep) side of 

the curve. A pressure margin of approx. 

15% from the stall point is recommended. 

Stall 

margin 

Stall

Fan characteristic 

Operating point 

In selecting fans and their control systems, 

care should be taken to ensure 

that all operating points of the envisaged 

control range lie within the stable 

area of the fan characteristic. 

Flow direction 

Direct-driven fans are available with 

the airflow direction "D" (motor in 

outlet) or "S" (motor in inlet). The 

catalogue shows the characteristic 

curves for airflow direction "D" units. 

For "S" type fans, a correction of the 

fan characteristic must be applied as 

follows: 

Volume flow + 5 % 

Total pressure increase + 10 % 

In addition, 5% should be deducted 

from the efficiency value. 

Belt-driven fans are available with airflow 

direction "D" only. 

If - for whatever reason - a belt guard 

is to be provided inside the fan, an 

output reduction must be expected. 

The impellers are not designed for reversible 

or contra-rotating operation. 


WITH ADJUSTABLE BLADES AT REST 

SIZING INFORMATION 

Air inlet/outlet 

Our characteristic curves are based 

on the assumption that a uniformly 

swirl-free velocity distribution prevails 

at the fan inlet. It may therefore be necessary 

to install a bellmouth inlet in 

the case of free intake configurations, 

or to fit appropriate guide panels if the 

fan operates immediately downstream 

of a duct elbow. 

Antivibration mounts 

Size 224 – 900 fans operating at 

1000+ rpm and size 1000 – 2000 fans 

with speeds exceeding 750 rpm can 

be fitted on rubber antivibration 

mounts. 

Determining motor output 

We recommend that the calculated 

shaft horsepower (PW) should be increased 

by the following percentages: 

Direct-driven fans +5% to 10% 

Belt-driven fans +10% to 20% 

Motor terminal box for AXO types 

All fans of this type (sizes 315 – 1000) 

are supplied with an exterior terminal 

box fitted on the casing and wired to 

the motor terminal box. 

Motor terminal box for AXN types 

Fans up to size 1250 are supplied with 

an exterior terminal box fitted on the 

casing and wired to the motor terminal 

box. 

Important notes: 

Direct-driven fans are available 

only with the motor output ratings 

indicated in our price lists. 

(Please inquire for special motors). 

The max. motor outputs for beltdrive 

fans are stated on the characteristic 

curve sheets on page 139 – 

155. 

For maximum acceptable motor 

sizes please refer to the dimensional 

diagrams on pages 007 – 011.

Acoustics 

All acoustic performance data are 

given in the characteristic curve 

sheets and on the "Acoustic Data" 

pages. The information supplied is 

valid for the stated rotational speeds. 

Acoustic data for other rpm levels 

can be derived by approximation 

using the following formulas: 

For lower rpm: 

L 1 = L 2 – 45 [log ( n2 )] 

n1 

For higher rpm: 

L 2 = L 1 + 45 [log ( n2 )] 

n1 

To correct for a greater distance: 

Distance in m 

Decrease in sound pressure level (dB) 

The acoustic emissions of multiple 

axial-flow fans operating at the same 

sound volume can be determined 

using the following table: 

Number of units 

Increase in sound level (dB) 

If two not equally loud axial-flow fans 

are operated simultaneously, the following 

correction values should be 

added to the higher acoustic level: 

Level difference [dB] 

Value to be added [dB] 

Fans with two or more speeds 

In the characteristic curves appearing 

below, the effect of the 

Reynolds number has been taken 

into account. As a result, the known 

laws of proportionality are not applicable 

to all fan sizes, specifically at 

small diameters and low speeds.

The ideal mounting configuration 

corresponds to that of the test airflow 

duct, with inlet and outlet tube diameters 

of 2.5 x D (D = fan diameter). 

Fig. 1 

200 

Flexible duct connectors upstream 

and downstream of the fan must be fitted 

carefully with zero offset, taking 

into account the installed length. Failure 

to observe this rule will result in 

performance loss and increased acoustic 

emissions. Flexible connectors are 

not intended as “elastic fit“ adapters 

compensating for installation inaccuracies! 

Where dampers must be fitted in airflows 

arriving vertically from below 

(e.g., through a ceiling or inlet duct), an 

opposed-blade damper type should be 

used to ensure an appropriate approach 

flow onto downstream deflector 

or baffle elements. 

The flexible duct connector (two nominal 

sizes > nominal fan size) ensures 

an additional improvement in incoming 

flow conditions and superior acoustic 

performance. 


INSTALLATION EXAMPLES 

2,5 x D 2,5 x D 

On free inlet fans, the use of an optimized 

bellmouth is mandatory. Failure to 

install this would result in severely degraded 

fan performance and increased 

noise levels. 

To satisfy accident prevention rules, a 

wire guard must be fitted to the front of 

the bellmouth.

a 

b = 0,6 x a 

at least five, ideally 

more (e.g., 8 baffles) 

With horizontal approach flows from a 

larger duct or inlet chamber, an oversized 

flexible connector (two nominal 

sizes > nominal fan size) in conjunction 

with the bellmouth will greatly improve 

incoming flow conditions and 

noise output. 

An approach flow situation as shown 

in Fig. 6 will result in a greatly impaired 

fan performance. 

Fig. 5/5.1 Fig. 6/6.1 Fig. 7/7.1 

036 

Connections of the above type are absolutely 

unacceptable in practice. 

2,5 x D 

In special cases, i.e., where no alternative 

is feasible, an adapter cone and 

2.5 D tube section (D = fan diameter) 

must be fitted as shown. 

Installation of an axial-flow fan directly 

downstream of a curved duct section 

will give rise to substantial performance 

losses and noise increase. 

If a 2.5 x D inlet flow section cannot be 

fitted, baffles should be used (for configuration 

and sizes refer to Fig. 5.1)


Phone: +49.6621.950-0 · Fax: +49.6621.950-100 

In a free-outlet configuration, the dynamic 

pressure acting on the fan’s annular 

surface area (fan surface minus 

hub surface) must be taken into account 

as impact loss. 

Fig. 8/8.1/8.2 

To avoid high impact loss, turbulence 

effects and excessive noise, downstream 

splitter attenuators should be 

connected via a diffuser with internal 

core and an interposed pressure 

chamber. In systems with large cross 

sections, the pressure chamber may 

be additionally provided 

Curved leading ends 

Baffle screen 

Diffuser with

Free outlet Free outlet 

0,5 x D 

On a free outlet system with 2.5 x D outlet 

duct, the entire surface area as determined 

from the nominal fan size may be 

used for the impact loss calculation (rectified 

flow). 

In-chamber installation 

The same applies by 

analogy for installation 

in tube or channel 

ducts. 

In practice, fans are often mounted in 

such cramped conditions that proper 

maintenance or repairs are impossible 

or extremely costly to carry out. Fans 

are machines which comprise wearing 

parts. It is therefore important to provide 

adequate free space around the unit for 

maintenance or repair access. On roofs 

(especially warm roofs), the availability

2,5 x D 

In large inlet chambers with multible air 

streams, vortex effects may impair the 

airflow at the fan inlet. Performance losses 

are an inevitable result. In this type 

of operating situation, the recommended 

anti-vortex baffle should either be 

fitted from the start or planned in such a 

way it can be installed later.
