Three-layer sintered mesh for demanding process filtration
Engineered with a protective outer wire mesh, a micro-aperture control layer, and a rigid structural support mesh. Diffusion-bonded under high temperature and vacuum to eliminate wire displacement, fiber shedding, and structural distortion under cyclic delta-P.
Solid-state vacuum diffusion bonding (1150°C)
