Belt-driven, Single-inlet Centrifugal Fans
The type GT CENTRIMASTER belt-driven, singleinlet centrifugal fans cover air flows up to 27 m3/s
and pressure rises up to 3.300 Pa. The fan series consists of centrifugal fans available with two types of
impeller:
– Impeller with forward-curved blades for the GTLF
fans
– Impeller with backward-curved blades for the
GTLB and GTHB fans
The backward-curved blades in the GTLB fans have
the same aerodynamic characteristics as those in the
GTHB fans, but the GTHB is a reinforced version
for higher speeds.

Versions
Besides the normal version, the fans are also available
in a spark-proof version. The smoke extraction version
of GT has been tested by the French CTICM institute and by the Russian VNIIPO institute.
CTICM has tested the fans for +400 °C, 2 hours and
the tests cover GTLB-3-025–140 as well as GTLF-3031–071. VNIIPO has tested the fans for +400 °C, 2
hours and for +600 °C, 1 hour and the tests cover all
single inlet GT-fans. As compared with the normal
version, the fans in the smoke extraction version have
metallic bearing dampers.
The fans in the spark-proof version conform to the
provisions of German Standard VDMA 24 169 3.1 –
3.2 and 3.4.
The inlet cone is made of brass and in the GTLF fans
the inlet is fitted with a brass band.
GTLB
The single-inlet fans are rated for continuous operation at temperatures up to +80 °C if the inlet of the
fan is connected to the ducting. If the motor is exposed to the air stream, i.e. on afree inlet fan, the ambient temperature must not exceed +40 °C. Motors for
higher temperatures are available to special order.

Design
Fan Casing – Sizes 025–071
Fan Inlet
The fan casing is made of Sendzimir galvanised sheet
steel. The casing side plates are stamped in one piece
and the inlets are deep-pressed in the end walls. The fan
casing is jointed by the "Pittsburg folding method"
which produces tight, strong joints. This jointing method and the deep-pressed inlets guarantee a stable
design and high, consistent quality. The fan tongue has
been specially designed to offer optimised aerodynamic
properties.
The design of the fan inlet is of vital importance to high
fan efficiency and a low level of sound generated by the
fan. On the size 025–071 GTLF fans, the inlet is directly deep-pressed into the end walls. On the GTLB and
GTHB fans the inlet must be deeper and must also
extend into the impeller with a certain amount of overlap and a small, accurately predetermined radial gap.
The inlet cones of the GTLB and GTHB fans are deepdrawn in one piece and are fitted to end walls of GTLF
fans. This means that the GTLB and GTHB fans have a
"double inlet" that gives the fan casing additional rigidity. On the size 080–140 fans, the inlet cone is made
separately for both types of fan and directly fitted to the
end walls.
Fan Casing – Sizes 080–140
The fan casing is made of Sendzimir galvanised sheet
steel. The casing of the size 080 and 090 fans is jointed
by the Pittsburg folding method and the casing is as
standard equipped with a stable, welded frame. The
casing of the size 100–140 fan consists of five flanged
sections that can be dismantled.

Fan Impellers
Shafts
The fan impellers with backward-curved blades (GTLB
and GTHB) are made of sheet steel and welded, coated
with 60 mm thick epoxy powder, (colour: AM 8043,
dark grey). The fan impellers with forward-curved blades (GTLF) are made of Sendzimir galvanised sheet
steel. The impellers of the size 040–140 GTLB and
GTHB fans are dynamically balanced to an accuracy to
ISO 1940–1973 G 2.5 at the maximum speed. The
impeller of the size 025–031 GTLB fans and all sizes of
GTLF fans are dynamically balanced to accuracy according to ISO Standard 1940–1973 G 6.3 at the maximum speed.
The impeller of the size 025–100 fans is secured to the
shaft by means of a key.
The shafts are made of steel and are provided with keyways for the belt pulleys. The shafts are designed with a
high factor of safety against fatigue, and for a critical
speed, which is at least 20% higher than the maximum
fan speed. The shafts have anti-corrosion protection.

Bearings
The size 025–071 GTLB and GTLF fans are equipped
with single-row, deep-groove ball bearings (Y-bearings)
that are permanently lubricated and sealed on both
sides. These bearings are secured to the shaft by means
of an eccentric locking collar. The bearings are supported by robust three-armed or four-armed bearing support.
The size 080–100 GTLB fans are equipped with singlerow, deep-groove ball bearings seated in plummer
blocks with grease nipple. These bearings are secured to
the shaft by means of a tapered adapter sleeve. The
bearings of the GTLB and GTLF fans are designed for a
life cycle of 20.000 hours. The plummer blocks with
grease nipple are supplied as accessories for the size
025–071 GTLF and GTLB fans. See under Accessories.
Bearing of the type GTLF and GTLB fans up to size 071.
The size 040–071 GTHB fans are equipped with singlerow, deep-groove ball bearings that are permanently
lubricated and sealed on both sides. These bearings are
secured to the shaft by means of a tapered adapter sleeve. This means that the dimension of the bearing increases by 5 mm in relation to the shaft and this increases
the useful life of the bearing. The bearings are supported by a robust three-armed or four-armed bearing support. Plummer blocks with grease nipple are also available as accessories.
Bearing of the size 080 – 100 GTLB fans.
The size 080–100 GTHB fans and the size 112–140
GTLB fans are equipped with plummer blocks with roller bearings secured to a sturdy bearing bracket made of
welded flat iron bar. All the roller bearings are as standard equipped with grease nipples.
The bearings of the GTHB fans are designed for a life
cycle of 40.000 hours.

The shaft power (P, kW) and the recommended min.
permissible motor output for direct on-line starting
(PM, kW) are specified in the fan charts, i.e. the safety
factor is already included. Base your motor selection on
this PM figure.

The safety factor covers belt losses that arise with standardised belt pulleys.
Recommendations:
When selecting GTLB and GTHB fans (with backward-curved blades) that at a given speed have an output peak within their operating range, use this output
peak for selecting a motor and not the output at the
duty point.
When selecting GTLF fans (with forward-curved blades) whose power demand, at a given speed, continuously increases as the air flow increases, use the shaft
power demand P at the duty point (adding the safety
factor!) or the recommended min. permissible motor
output PM. If you cannot with certainty plot the duty
point in the fan chart, select a motor for an output
that is another 15–20 % higher.
Motor
The GT fans are normally supplied with the motor
mounted. This enables the fan to be trial run prior to
dispatch and ABB can assume undivided warranty liability. If the fan is supplied without motor, the size and
speed of the motor must be specified when the order is
placed so that the correct belt drive can be selected.
Detailed motor data is tabulated in separate tables. See
under Motor Data.
Belt Drive
The belt drive consists of belt pulleys and belt(s). The
pulleys have a separate Taper-Lock-type hub, which is
easy to fit and remove.
The belt guard and slide rails are included in the GT
fan delivery.

The calculated starting time is the time during which the stardelta starter must be in star for the fan to reach about 90 % of
full speed, whereupon the starter switches over to delta.
On star-delta starting, also check that the motor curve is higher than the fan torque curve during the star connection period. The lowest possible motor rating for star-delta starting can
be calculated from the following expression.

The charts for fans with backward-curved blades include a
kη scale that indicates how much the efficiency will decrease if the fan is running at low speed. This scale can be
applied with high precision within the normal operating
range at which the power consumption of the fan at a
given speed is fairly independent of the air flow.
The bearing losses are included in the power consumption of the fan and influence its efficiency.
The power consumed by the fan is defined in the fan
chart as the power consumed at the shaft end and thus
contains the bearing losses. The efficiency figures in the
chart are applicable to a fan operating at max. speed.

Acoustic Data – Explanation
Distance absorption
The following formula is used to obtain the sound pressure level LpA(s) on free sound emission to the surroundings (sound paths 3 and 4) at various distances L:
LpA(s) = LWA(s) – ∆L
where the distance absorption ∆L can be obtained from
the table below:

Example:
GTHB-3-045: Air flow qv = 2.2 m3/s, total pressure rise ∆pt = 1800 Pa.
From fan chart:
Speed n = 2670 r/min.
Power demand P = 5.25 kW.
Fan efficiency η = 0.996 x 80% = 79.7%.
A-weighted sound power level to outlet duct LWA = 95.7 dB(A).
If the fan has a ducted inlet and outlet, the sound level at each octave band and the
total sound power level for each sound path will be the following:
Inlet duct:
LW63Hz = 95.7 – 2 = 93.7 dB
LWA = 95.7 + 0.8 = 96.5 dB(A)
LWt = 96.5 + 3.3 = 99.8 dB

The A-weighted sound power level at a distance of one metre from the fan will be: LpA = 89.3–7 = 82.3 dB(A)
If the fan has an open discharge, the A-weighted sound power level at the fan outlet will be:
LwA = 95.7–0,1 = 95.6 dB(A).
The corresponding sound power level at a distance of 50 metres will be: LpA = 95.6–42 = 53.6 dB(A).

The current values in the tables are applicable to motors wound for 400 V. All motors can be used for voltages between 380 and 420 V.
Motors with voltage code c=1 can be connected in delta to operate in the range of 220–240 V.
Motors with voltage code c=2 can be connected in star to operate in the range of 660–690 V.
The correction factors on the current in the range of 400 V will then be: 220–240 V = 1.73 and
660–690 V = 0.58.
Code suffix for voltage (c)
1 = 220–240 V delta/380–420 V star
The motors can also be wound for 500 V, and the voltage code is then c=5. The correction factor on the
current at 400 V is then 0.8.
5 = 500 V star (sizes 71–100)

1) Correction factors
The current values in the tables are applicable to motors wound for 400 V. All motors can be used for voltages
between 380 and 420 V.
Motors with voltage code c=1 can be connected in delta to operate in the range of 220–240 V.
Motors with voltage code c=2 can be connected in star to operate in the range of 660–690 V.
The correction factors on the current in the range of 400 V will then be: 220–240 V = 1.73 and 660–690 V = 0.58.
The motors can also be wound for 500 V, and the voltage code is then c=5. The correction factor on
the current at 400 V is then 0.8.
The speeds, efficiencies and power factors are applicable at 230, 400, 690 and 500 V.

GTLZ-50, 51, 52 Flow measurement devices
The flow measurement device is used for measuring the
air flow in type GT fans. This is done by measuring
the differential pressure in the device. The flow measurement device should be mounted in the fan inlet. The
air flow is calculated as a function of coefficient k and
the differential pressure reading ∆pm in the following
manner:
1
q=— x
k
där q
∆pm
k
GTLZ-53, 54, 55 Flow measurement devices
The flow measurement device is supplied with a manometer as well. The supply includes flow measuring device, manometer with scale and mounting bracket for the
measuring device and hoses. For a technical specification,
see the GTLZ-50, 51, 52 on the preceding page.

= air flow (m /s)
= differential pressure reading (Pa)
= coefficient unique to the fan selected
The air flow that corresponds to the differential pressure reading can most easily be read with a manometer
whose scale is graduated in accordance with the function above for a specific fan. On request, detailed
charts can be supplied. The accuracy of the readings is
±10 %. If the flow measurement device is recalibrated
at the site (for instance in an air handling unit), an
accuracy of ±5 % can be achieved.
