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.

Design 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.

Design 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.

Materials and Finish, Motor Selecting the Motor
Materials and Finish
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 GX fans in the standard version meet the provisions of Environmental Class M2. Fan casing: Inlet cone: Shaft: Fan impeller:
Sendzimir galvanised sheet steel, (275 g/ m2 thick zinc) Sendzimir galvanised sheet steel in the normal version. Brass in the spark-proof version. Centreless-ground steel with anti-corrosion protection. GTLB and GTHB: Sheet steel, welded, coated with 60 mm epoxy powder and baked, colour: AM8043, dark grey. GTLF: Sendzimir galvanised steel.
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.

= Correction factor for the efficiency kη = Recommended operating range = Recommended operating range of a heavy-duty fan
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.

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).

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.
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) 500 V delta (sizes 112–315)
The speeds, efficiencies and power factors are applicable at 230, 400, 690 and 500 V.

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.
Code suffix for voltage (c) 1 = 220–240 V delta/380–420 V star
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.
2 = 380–420 V delta/660–690 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.
Temperature sensors in the stator winding, code suffix (d) 0 = without 1 = with bimetal temperature contacts 2 = with thermistor
The speeds, efficiencies and power factors are applicable at 230, 400, 690 and 500 V.
2)
lst = Ratio of motor starting current to full-load current.

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.
pm
3
= 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.
