3 Technical brochure High erformance Tangenial Fans,, Many producion processes require a linear exended and absoluely even disribuion of air or oher es o he working area. ecause of heir special design, angenial fans mee his requiremens in he bes possible way. The rigid design and he use of high qualiy maerials securealongservicelife. y he working principle, ha does away wih addiional baffles and vanes and he space saving design, he use of angenial fans is very economic. Flow principle The air inake of angenial fans akes place over he whole lengh of he ouer impeller periphery. The air hen flows ino he impeller inerior where i is reversed and acceleraed by he vorex caused by he impeller roaion. Finally he air is disribued a he discharge side over he whole impeller lengh. In his way he air flows hrough he impeller firs from ouside o inside and hen from inside o ouside. The impeller is a cylindrical cage of forward curved impeller blades wih wo or more supporing discs. The vorex separaes sucion side and discharge side a he narrowes line beween impeller and vorex inducer and causes he flow paern ogeher wih he scroll. Advanages Uniform air flow over he enire fan widh. Addiional baffles, plenums and guide vanes are no required. pace saving due o a 0_ airflow deflecion. The fan widh can be exacly mached o he machine widh. The air flow paern does no change wih wider machines (simplifies design and drawings of modular sysems). Works equally well in any arrangemen (righ hand drive or lef hand drive available). ow noise operaion due o aerodynamically good impeller and scroll shape. Impeller bearings ou of air flow. Many bol-on opions. Fields of applicaion Examples of ypical fields of applicaion are: bakeries, drying sysems, indusrial ovens, packaging indusry, cooling and refrigeraion, deparmen sores, auomobile indusry, agriculural machines, surface reamen, conrol panels, hardening shops,exile engineering,swimming pools, air reamen, papermaking indusry, environmen simulaion, chemical indusry, indusrial processing engineering, dus collecion.

The sound pressure level in he free field in 1 m disance (full spheric sound radiaion) is ab. d less han he sound power level. The equaion for he unweighed sound power level according o VDI 81 is: W = Wspec +10 lg V + lg p.for he oal pressure p use a and for he air volume use m /s. Greasing frequency A bearing emperaures above +0_C he frequency of greasing mus be increased by wo imes wih every +1_C emperaure rise. Don' exceed he emperaure raing of he grease. A operaing emperaures below +0_C he frequency of greasing is reduced. A operaing emperaures below +_C heime beween greasing can be doubled. The greasing requiremens are also influenced by several oher facors. In case of verical insallaion for example he frequency is doubled. Harsh operaing and environmenal condiions as well as variable speeds also have a shorening effec on he greasing frequency. In such cases please conac TG Akiengesellschaf.
