Sedifilt Technology

True Depth Filtration

Sedifilt depth filters have revolutionized filtration with a superior technology that overcomes the limitations and drawbacks of other filters.

Superior Filtration Technology

Sedifilt technology produces superior depth filters with increased filtration capacity, longer lifetime, and higher performance that reduce overall costs. Sedifilt filters have high structural integrity combined with a greater void volume, giving a lower pressure drop, much improved dirt holding capacity and efficiency compared to conventional filters. Sedifilt filters are made of polypropylene, a recognized environmentally safe and recyclable material for purity and ease of disposal.

How it Works

Illustration of Sedifilt graded density structure

The patented Sedifilt process begins with 100% pure polypropylene that is melt-spun (extruded) without the use of any chemicals. The extruded media consists of continuous filaments of multi-lobal cross-section with numerous micro voids between each individual filament. These chemical-free continuous filaments are then randomly oriented to each other, intermixed, looped and entwined into a non-round, highly stable, bulky yarn. The multi-lobal cross-section of filaments combined with the random yarn structure gives much improved void to solid ratio. This improved porosity gives a higher dirt holding capacity and reduced resistance to flow.

Comparison with conventional media

Sedifilt Media

High bulk, stable, three-dimensional random structure comprising continuous filaments.

Sedifilt multi-lobal cross section of individual filaments has more micro-voids giving higher dirt holding capacity and lower resistance to flow.
