Fluidyne Spark Arrestors or spark traps are used for providing a safe exhaust as exhaust leaks are a hazard to employees and workers and hamper engine performance. Sparks are a source of ignition for factory, forest and brush fires. These safety issues are of prime concern and compliance can be met by providing Fluidyne Spark Arrestors that are trap type Spark Arrestors that have a method for removal of accumulated carbon particles, for improved maintenance ease. Three spark arrestors or trapshave exhaust manifolds in two basic configurations, a four-stack design with individual manifolds and stacks, and a two-stack manifold. Fluidyne Spark Arrestors are CCOE approved.
