LTG Tangential Fans an advantage for best heating, cooling, drying, blasting
Many production processes require a linear extended and
absolutely even distribution of air or other gases to the
working area. Because of their special design, tangential
fans meet this requirements in the best possible way.
The rigid design and the use of high quality materials secure a long service life. By the working principle, that
does away with additional baffles and vanes and the space
saving design, the use of tangential fans is very economic.
Flow principle
The air intake of tangential fans takes place over the
whole length of the outer impeller periphery. The air then
flows into the impeller interior where it is reversed and
accelerated by the vortex caused by the impeller rotation.
Finally the air is distributed at the discharge side over the
whole impeller length. In this way the air flows through
the impeller first from outside to inside and then from inside to outside. The impeller is a cylindrical cage of forward curved impeller blades with two or more supporting
discs.
The vortex separates suction side and discharge side at the
narrowest line between impeller and vortex inducer
and causes the flow pattern together with the scroll .
Advantages
• Uniform air flow over the entire fan width. Additional
baffles, plenums and guide vanes are not required.
• Space saving due to a 90 ° airflow deflection.
• The fan width can be exactly matched to the machine
width. The air flow pattern does not change with wider
machines (simplifies design and drawings of modular
systems).
• Works equally well in any arrangement (right hand drive
or left hand drive available).
• Low noise operation due to aerodynamic design based
on 25 years experience.
• Impeller bearings out of air flow.
• Many bolt-- on options.
Fields of Application
LTG tangential fans are used for needs of regular air flow
over large areas:
Heating, cooling, drying and dust collection. Examples of
typical fields of application are bakeries, drying systems,
industrial ovens, packaging industry, cooling and
refrigeration, department stores, automobile industry,
agricultural machines, surface treatment, control panels,
hardening shops, textile engineering, swimming pools,
air treatment, papermaking industry, environment
simulation, chemical industry, industrial processing
engineering, dust collection, electrical equipment.

Acoustical Data
Drive Side
With the suction opening on top, viewed against the
discharge opening, the drive pulley is bolted on optional
either right hand (TWR) or left hand (TWL).
The acoustical data are for discharge side, tested in a reverberant field.
The A-- weighted sound power level LWA can be transformed into a A-- weighted sound pressure level LPA by the
equation LPA=LWA- 10 log s/1 m2.
Accessories and Special Versions
The sound pressure level in the free field in 1 m distance
(full spheric sound radiation) is abt. 11 dB less than the
sound power level.
For extra high corrosion protection requirements, the impellers can be made of stainless steel.
Belt pulley:
V-- belt pulley with sleeve, dW = 160 mm (6.3 inch),
profile SPA 12.5 mm (0.49 inch), DIN 7753.
The equation for the unweighted sound power level according to VDI 2081 is:
LW=LWspecific+10 log V + 20 log ∆pt
For the total pressure ∆pt use Pa and for the air volume V
use m3/s.

General Remarks
Installation / Initiation
Belt pulley and taper clamping sleeve are made from grey
cast iron GG 20.
- Clean and degrease all shiny surfaces. Insert taper clamping sleeve into the hub and bring bores to a flush.
- Slightly grease screws and insert. Do not yet tighten the
screws.
- Clean and degrease shaft. Push belt pulley with taper
clamping sleeve to the desired position on the shaft.
- Tighten the screws uniformely, alternating between the
sides and using a moment of 20 Nm.
- Check the moment of the screws after a short period of
service (1/2 to 1 h) and correct if necessary.
- To keep foreign bodies from entering the empty bores,
fill them with grease.

Position of the Fan
Tangential fan with shaft end on the drive side.
Any arrangement is possible.
Rigid bolted, corrosion proof casing of marine grade aluminium (DIN 1725). Impeller of galvanized steel.
Installation and Start Up
The impeller is both sides bedded in self-- aligning ball
bearings. Bearing design life is 25 000 hours. The counterside bearing is mounted vibration dampened. Both bearings are lifetime lubricated.
Recommended V-- belt pulley:
profile SPA 12.5 mm (0.49 inch), dw = 160 mm (6.3 inch).
DIN 7753.
The maximum rated power transmission for the pulley is
9 kW (12 hp).
Intake and discharge openings have sealing planes and
plug in slots to connect exactly to ducts and appliances.
The complete fan (including bearing clearance etc.) is balanced to grade Q 6.3 according to VDI 2060.
Fix the fans without any distortion to a plane base frame.
For fixation of the fan use only the bolt holes provided in
the side elements.
To connect to ducts and appliances sealing planes are provided over the whole fan width for the intake and discharge openings.
Make sure to observe the applicable safety codes before
starting the fans.
Check V-- belt selection for higher temperature applications.
The fans are designed for continuous operation with constant load (operation mode S1 analogous to VDE 0530):
For frequent start/stop operation please check with LTG.
Length tolerances acc. to ISO 2768 vL.

Acoustical Data
Drive Side
With the suction opening on top, viewed against the
discharge opening, the drive pulley ist bolted on optional
either right hand (TWR) or left hand (TWL).
The acoustical data are for discharge side, tested in a reverberant field.
The A-- weighted sound power level LWA can be transformed into a A-- weighted sound pressure level LPA by the
equation LPA=LWA- 10 log s/1 m2.
Accessories and Special Versions
The sound pressure level in the free field in 1 m distance
(full spheric sound radiation) is abt. 11 dB less than the
sound power level.
For extra high corrosion protection requirements, the impellers can be made of stainless steel.
Belt pulley:
V-- belt pulley with sleeve, dW = 160 mm (6.3 inch),
profile SPA 12.5 mm (0.49 inch), DIN 7753.
The equation for the unweighted sound power level according to VDI 2081 is:
LW=LWspecific+10 log V + 20 log ∆pt
For the total pressure ∆pt use Pa and for the air volume V
use m3/s.

General Remarks
Installation / Initiation
Belt pulley and taper clamping sleeve are made from grey
cast iron GG 20.
- Clean and degrease all shiny surfaces. Insert taper clamping sleeve into the hub and bring bores to a flush.
- Slightly grease screws and insert. Do not yet tighten the
screws.
- Clean and degrease shaft. Push belt pulley with taper
clamping sleeve to the desired position on the shaft.
- Tighten the screws uniformely, alternating between the
sides and using a moment of 20 Nm.
- Check the moment of the screws after a short period of
service (1/2 to 1 h) and correct if necessary.
- To keep foreign bodies from entering the empty bores,
fill them with grease.
LTG Accessories
V-- belt pulley 1 x SPA Ø 160 mm (6.3 inch)
incl. clamping sleeve Ø 24 mm (0.94 inch)
Material No. 1004586
Detachment
- Loosen all screws. Remove one or two of them completely, grease and insert them into the ejection bores.
- Remove belt pulley with sleeve from the shaft.
