Metal Fiber & Mesh Filters

Metal fibers are becoming more and more common, they have been traditionally been used as partial devices but in recent months more alternatives are being developed for the use as filters using a process defined as sintering, DET’s is also working with technology but to date it is not commercially available. Other alternatives have been wire mesh based or corrugated wrapped layers of metal foils making them the monolith / substrate.Suchcores have the advantage that a current can be passed through the monolith to heat the core for regeneration purposes.Metal fiber cores tend to be more expensive than cordierite or silicone carbide cores, and generally not interchangeable with them as they are not truly a trap.
These devices can also be used as pre filter devices to aid flow and dispersion of particulates into a filter substrate.
