Full Product Description
For years,the railroad industry has recognized that paper-type engine air filters offer the best in efficiency, engine protection, and overall performance. However, bag-type filters have remained the preferred choice for many because of their ease of application and regular change out cycles.
The TieRun B series bag air intake filters combine the best of both worlds. A new concept in locomotive air filtration, this design integrates the high efficiency and trouble-free performance of paper type filters into the popular bag configuration.
Bag filters are ofter the last line of defense for the combustion air of a locomotive or the air of an industrial process. The multi-layered design provides gradients that allow for higher efficiency and lifetime to provide maximum performance and meet long service intervals.
Extended tests of the B series bag air filter were performed at major railroads. The results of the pressure drop readings and laboratory analysis revealed that the bag filter would last at least six months and still have life remaining. With its six-month recommended change out cycle, the bag filter offers double the life of conventional bags, yet it doesn't cost twice as much. An additional benefit of eliminating up to two change outs per year, is a reduction of both filter and labor costs.
Standard filtration efficiencier required in many applications are 96-98%. However, in very dusty environments such as desert or mining applications, many customers prefer the extra protection of 99%+ provided by TieRun high efficiency bag filter. Higher filtration efficiency means lower dirt penetration and enhanced removal of harmful mico-fine particles, resulting in better protection and longer engine life.
The B series bag filter uses a special outer layer of material that keeps the oil inside the bag and out of turbochargers ,aftercoolers, and engines. And because the bag doesn't dry out from oil migration, the service life is extended. The versatile bag filter is ready to install in any existiing bag housing, with a filter that remains dry and oil-free, so it's cleaner and easier to handle than a conventional bag.
