Superior filtration technology

Super Fine depth filter cartridges use a proprietary spun-bonding technology to offer:

â–  extended service life
â–  fewer filter change-outs
â–  consistent particle reduction
â–  increased surface area
â–  low initial pressure drop
â–  high particle reduction efficiencies
â–  high flow rates

Depth filter cartridges

The unique Super Fine filter manufacturing process combines process control with quality assurance enabled by an
ISO 9001 certified quality system to provide consistent product performance. The proprietary manufacturing process
provides a high degree of fiber-to-fiber thermal bonding, without the use of binders, to produce a rigid, core-less, filter
structure with the following properties:

■ does not unload contaminants with increasing differential pressure like typical spun-bonded filters
■ exhibits exceptionally low differential pressure for a given filter rating

Consistent filtration throughout the service life of a depth-style filter depends on how well the filter’s structure
tolerates fluctuations in operating conditions – including contaminant loading and differential pressure. Flexible
structures, such as those found in typical filters, tend to compress and change porosity with increased pressure, while
rigid structures do not. Media compression can result in short filter life because the pores collapse and ultimately
close. Media compression can also cause the filter to release already held particles.
The robust Super Fine filter captures and retains contaminant within its rigid filter matrix, even under increasing
differential pressure. The unique depth filter structure of the Super Fine filter provides a significant increase in
contaminant holding capacity and provides greater flow capacity at a given pressure.
