To calculate the startingtime in direct on-line startingUse the following formula:

The calculated starting time is thetime needed for accelerating thefan from rest to full speed.

To calculate the startingtime in star-delta startingUse the following formula:

The calculated starting time is thetime during which the stardeltastarter must be in star for the fan toreach about 90 % of

full speed, whereupon the starterswitches over to delta.On star-delta starting, also checkthat the motor curve is higherthan the fan torque curve duringthe star connection period.The lowest possible motor ratingfor star-delta starting can be calcu-lated from thefollowing expres-sion.

Symbols usedP = motor rating, kW.

Pm1) = power demand withthe fan running atrated speed (includ-ing any belt-drivelosses), kW.

PY/D = lowest rating ofmotor for whichstar-delta staringcanbe employed, kW.

Mst 3) = ratio of motor start-ing torque to nor-mal torque.

Mmax3) = ratio of maximummotor torque tonormal torque.

nf = rated speed of fan,r/min.

J2) = Moment of inertiaof the systemreferred to the fanshaft, kg m2.

t = starting time, s.

1) Pm is given in the fan chart.

2) The moment of inertia of theimpeller is given in the fan-charts. The moment of iner-tia of the motor can generallybe disregarded.

3) See the catalogue of themotor supplier.

Selecting the MotorThe 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 safetyfactor is already included. Base your motor selection onthis PM figure. The safety factor covers belt losses thatarise with standardised belt pulleys.

Recommendations:When selecting GTLB and GTHB fans (with backward-curved blades) that at a given speed have an output peakwithin their operating range, use this output peak forselecting 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, continuouslyincreases as the air flow increases, use the shaft powerdemand P at the duty point (adding the safety factor!) orthe recommended min. permissible motor output PM. Ifyou cannot with certainty plot the duty point in the fanchart, select a motor for an output that is another 15–20 %higher.

Motor

MotorThe GT fans are normally supplied with the motor mounted.This enables the fan to be trial run prior to dispatch andFläkt Woods can assume undivided warranty liability. Ifthe fan is supplied without motor, the size and speed of themotor must be specified when the order is placed so thatthe correct belt drive can be selected. Detailed motor datais tabulated in separate tables. See under Motor Data.

Belt DriveThe belt drive consists of belt pulleys and belt(s). Thepulleys have a separate Taper-Lock-type hub, which iseasy to fit and remove.The belt guard and slide rails are included in the GT fandelivery.

Base frameBase frame of GTLB and GTLF is made of galvanizedsheet steel with exception of size GTLB-5-100. GTHBand GTLB-5-100 has welded base frame which is hot-dip galvanized.

Acoustic Data – Explanation

Acoustic dataThe sound power levels to the surroundings and to the outlet duct have been measured for each fan size. The fandiagram gives the A-weighted sound power level LWAfor the outlet side. The following formula is used to deter-mine the sound power level to the surroundings of a free-inlet fan, s = 2, or to the outlet of a free-discharge fan, s = 4:

LWAcan be read from the fan chart and the ∆LWA(s) can be obtained from theadjacent table .

The following formula is used to determine the total sound power level to different sound paths:

∆LWt(s) can be obtained from the adjacent table.

The following formula is used to determine the linear sound power level (not A-weighted) to different sound paths(to the discharge duct s = 1, to the surroundings of a free-inlet fan s = 2, to the outlet of a free-dischargelet fan s = 4):

Kokt(s) can be obtained from the adjacent table.

In general, the maximum sound power level occurs on the octave band that corresponds to the blade frequency.Acoustic data is given including the blade frequency.

LWA(s) = LWA + ∆LWA(s)

Motor Data – Single-speed Motors, 50 Hz

2 poles = 3000 r/min

Code suffix for voltage (c)1 = 220–240 V delta/380–415 VY

2 = 380–415 V delta/660–690 VY

1) Correction factorsThe current values in the tables are applicable to motors wound for400 V. All motors can be used for voltages between 380 and 415 V.

Motors with voltage code c=1 can be connected in D to operate in therange of 220–240 V.Motors with voltage code c=2 can be connected in Y to operate in therange of 660–690 V.The correction factors on the current in the range of 400 V will thenbe: 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 thenc=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.

The fan casing, impeller and bearing bracket as well asaccessories are coated with 100 µm thick epoxy powderand baked. The colour is AM 8043, dark grey. All boltsand nuts are made of stainless steel. The coating processand epoxy powder are the same as in version d = 1; thecoat is 100 µm thick in one layer.

d = 3 Wet painting 250 µm, finish in three coats.

The fan casing and bearing bracket as well as accessoriesare painted with 250 µm thick epoxy in 3 layers. Thecolor is AM 8043, dark grey. The impeller is coated with100 µm thick epoxy powder. All bolts and nuts are madeof stainless steel.

Air flow measurementDouble inlet GT-fans can be equipped with an airflowsensor for the measurement of airflows. The measure-ment method is based on differential pressure betweenpressure on inlet cone on specified place and the refer-ence pressure upstream of the inlet cone. The pressuredifference is calibrated for each fan size.

where Qv = air flow (m3/s)∆pm = differential pressure readingk = k-factor for specific fan

The corresponding air flow related to the differential pres-sure can easily be read by means of manometer(not included into the delivery).The accuracy of the air flow sensor is depending on the airflow conditions inside the air handling unit. Theaccuracy of +- 5 % can be achieved by calibration under thefinal operating conditions. Without calibrationthe accuracy is +- 7-10 %.The k-factors are valid for air density 1.2 kg/m3.
