Features and benefits
The following tables provide information about the features, benefits, characteristics, and performance of Pall standard metallic media. They serve as basic references for selecting a filtration medium. Your Pall representative will provide more detailed product information and help you choose the product that is most appropriate for your application.

Fiber metal: Fibermet™ media, PMF® media

Feature	Associated Benefit
Resists high temperatures and pressures	Can be used for a wide variety of applications
High porosity/high permeability	Exceptional dirt-holding capacity and longer on-stream  life
Can be cleaned repeatedly for reuse	Reduced operating and disposal costs
Graded or uniform pore structure	Highly efficient removal of hard and deformable gel-type contaminants

Micron-level metallic fibers are key to the exceptional performance of Fibermet and PMF media.

Wire mesh: Dynamesh™ media, Rigimesh® media

Feature	Associated Benefit
Closely controlled pore size distribution	Consistent, repeatable filtration results
Excellent mechanical strength	Can be used at high temperatures and differential pressures
Resists unloading, even under severe shock conditions	Specially suited for applications with adverse pressure conditions and low contaminant loading
Retains both rigid and deformable	Assured absolute particle retention

Rigimesh and Dynamesh media are made of precision woven wires to ensure consistency and strength.

Powder metal: PSS® media

Feature	Associated Benefit
Mechanical strength	Reliability and longer on-stream life
Media available in a variety of alloys	Capable of tolerating high temperature chemical processes
High durability	Assured chemical compatibility with process fluids; can be cleaned repeatedly for reuse
Ability to withstand reverse flow	Lower maintenance costs
Uniform permeability	Low resistance to flow

The PSS medium has a uniform particle distribution that produces precise pore openings without the use of binders.

Composites: PMM® media

Feature	Associated Benefit
Very fine removal efficiencies	Efficient cake formation and release for solids recovery applications
Thin, fine, pleatable depth filtration media	Higher surface area
Can be cleaned repeatedly for reuse	Reduces solids loading of final filters; economical choice for many prefiltration applications
High dirt-holding capacity	Longer service between cleanings

The Supramesh medium combines the filtration features of powder metal with the strength of wire mesh.
