TieRun B series bag filters offer a truly innovative design. Providing long life protection for combustion air on locomotives, gen-sets, and other applications that demand a high air flow, TieRun bag filter offers proven performance.
Full Product Description
The TieRun B series bag air intake filters combine the high efficiency and trouble-free performance of paper type filters into the popular bag configuration. The multi-layered design provides gradients that allow for higher efficiency and lifetime to provide maximum performance and meet long service intervals.
Extended tests revealed that the bag filter would last at least six months. With its six-month recommended change out cycle, it offers double the life of conventional bags, reducing both filter and labor costs. In dusty environments like desert or mining, the high efficiency bag filter provides 99%+ protection, resulting in lower dirt penetration and longer engine life.
The B series uses a special outer layer that keeps oil inside the bag and out of turbochargers and aftercoolers. Since the bag doesn't dry out from oil migration, the service life is extended. It remains dry and oil-free, making it cleaner and easier to handle during installation.
