LTG High Performance Tangential Fans-an advantage for best heating, cooling, drying, blastingMany production processes require an extended linearand absolutely even distribution of air or other gases overa certain area.

The special design of, High Performance Tangential Fansprovides the optimum solution for these requirements.

The robust design and the use of high quality materials as-sure a long life expectancy.

The way these fans work, allowing even air distributionwithout additional baffles and vanes, and the space-savingdesign, make the use of tangential fans very economic.

Flow principleIn a tangential fan, the air is drawn in over the entire lengthof the fan impeller. Inside the impeller, the airflow isdivertedand accelerated by the vortex created by the rotation of theimpeller.

The airstream then exists over the entire length of the im-peller on the discharge side. The vortex separatesthe intake and discharge side of the fan at the narrowestpoint betwen the impeller and the vortex builder. Togetherwith the fan scroll, the vortex directs the airflow. This res-ults in an almost uniform laminar airflow over the entire out-let width of the fan.

impeller vortex inducer fan scroll

Advantages Uniform, extended airflow over large areas. Space-saving installation due to 90_ airflow pattern. Fan length can be matched exactly to machine width. Airflow conditions remain the same even for wider ma-chines (simplified design and drafting in case of modularsystems).

Fans performwell in any mounting position. Drive can bemounted on right or left hand side.

Quiet operation due to optimised impeller and housingdesign.

Long live expectancy due to robust design and locationof bearings outside the hot air zone.

Many bolt-on options.

Tangential fan series TMR 125 (right hand motor)note: TMR = right hand motor, TML = left hand motor



Specification and design featuresTangential fan with close coupled, spray water protecteddrive motor with terminal box.

Rigid bolted, corrosion proof casing of marine grade alu-minium. Side elements of stainless steel (1.4541). Impellerof galvanized steel.

On the drive side the impeller is bedded via an elastic coup-ling directly on the motorshaft, on the counter side it is bed-ded in a ball bearing mounted vibration dampened. Bear-ing design life is 25 000 hours.

Dimensions and performance data

Intake and discharge openings have sealing planes to con-nect exactly to ducts and appliances.

The complete fan is balanced to grade G 6.3 according toDIN ISO 1940/1.

* Due to different technical designs and compliance with EU regulations, the above dimensions may differ.** If using a 60 cycle net, it's necessary to prove the working point through LTG.



Position of the fanStandard arrangement is horizontal. For vertical mountingthe motor is located below.

Installation and start upFix the fans without any distortion to a plane base frame.For fixation use only the bolt holes provided in the side ele-ments.

To connect to ducts and appliances plug in slots and seal-ing planes are provided over the whole fan width for the in-take and discharge openings.

Make sure to observe the applicable safety codes beforestarting the fans.

The fans are designed for continous operation with con-stant load (operation mode S1 analogous toVDE 0530). For frequent start/stop operation please checkwith LTG.To keep the ambient temperature below max. at the bear-ings, it is necessary to insulate the side elements on site.

Motor arrangementWith the suction opening on top, viewed against the dis-charge opening, the drive motor is optional either right(TMR) or left (TML) hand side.

Electrical equipmentThe fan is driven by a 4-pole 3-phase motor,230 V / 400 V / 50 Hz.Enclosure is IP 55 accordingDIN 40050. This gives protec-tion against dust deposits and low-pressure jets from anydirection.

Fan curvesTest conditions for the fan curvesThe indicated curves are valid for an air density ofρ = 1.2 kg/m3, a supply voltage of U = 400 V withf = 50 Hz, if operated with a 4-pole motor.

The rating tests where done as laboratory test according toVDI 2044 with unrestricted inlet and discharge.

Fan curves for 400 mm nominal length,4-pole

Acoustical dataThe acoustical data are for discharge side, tested in a re-verberant field.

The A-weighted sound power level LWA can be trans-formed into a A-weighted sound power level by the equa-tion LpA = LWA -10 log S/l m2. For this the exact total applic-able panel area S can be used.

The sound pressure level in the free field in 1 m distance(full spheric sound radiation) is abt. 11 dB less than thesound power level.

Fan curvesTest conditions for the fan curvesThe indicated curves are valid for an air density of ρ = 1,2kg/m3, a supply voltage of U = 400 V with f = 50 Hz, if oper-ated with a 4 pole motor.

The rating tests where done as laboratory test according toVDI 2044 with unrestricted inlet and discharge.

Fan curves for 401 mm nominal length

Acoustical dataThe acoustical data are for discharge side, tested in a re-verberant field.

The A-weighted sound power level LWA can be trans-formed into a A-weighted sound power level by the equa-tion LpA = LWA -10 log S/l m2. For this the exact total applic-able panel area S can be used.

The sound pressure level in the free field in 1 m distance(full spheric sound radiation) is abt. 11 dB less than thesound power level.
