Porofelt Media  
Porofelt stainless steel filter elements trap contaminants throughout the filter media increasing surface area and dirt holding capacity. Manufactured from microscopic stainless steel fibers that are diffusion bonded to produce stainless steel filters capable of providing filtration down to 3 micron absolute.
- Fine filtration 40 to 3 micron absolute available
- Excellent dirt holding capacity
- Good filter permeability
- Particles trapped deep throughout the complex pore structure
