Fabrics: K-S Filtration Media

Komline-Sanderson Corporation – a leading manufacturer of liquid-solid separation systems – offers filtration media products from either synthetic or natural materials for use on:

  • Rotary Drum Vacuum Filters
  • Belt Filter Presses
  • Gravity Belt Thickeners
  • Horizontal Belt Vacuum Filters
  • Test Leaf Kit
  • Filter Presses (plate & frame or recessed chamber)
  • Many other types of liquid/solids separation equipment

Komline-Sanderson maintains a filtration media fabrication facility in Sparta, New Jersey. A broad knowledge of filtration, coupled with extensive practical experience, enables K-S to select the proper filter medium for any application, and to apply the best fabrication techniques for your specific requirements. Our large filter fabric inventory allows for quick processing of your order. In emergency situations, next day shipments can be provided—even of custom made products worldwide.

For orders, contact us at 1 (888) Call-4-KS (225-5457) ext. 33, or 1 (973) 579-0090 ext. 33.

Technical Service and Field Service

Technical and Field Services are available to all our customers. Our Technical Service Department operates a bench scale and pilot scale laboratory in our lab or right in your facility. Yes, we go right to the problem to give you the right solution!

We stock what we sell.

Not only the fast selling items but the occasional ones as well. We stock fabric, shock cord, caulking tools, edging, and closure materials.

Selection and Evaluation

The Filtration medium is the essence of any filter. Since filter applications vary widely, with differing characteristics from plant to plant – even in the same process – selection of the optimum filtration medium is critical to obtaining the desired results.

Ideally, the filter medium should offer no significant resistance to the flow of liquid, should retain the full size range of the solids being separated, should offer instant and complete cake release (solids removal), and be immune to blinding.

In many cases, experience gleaned from pilot testing or actual production installations is available to guide in the selection of the proper medium. When this data is not available, an accurate prediction of performance can be accomplished through filter leaf testing in the Komline-Sanderson laboratory or in your facility.

Komline-Sanderson’s lab personnel will test a sample of your present filter medium for its filtration characteristics, air permeability, weight, and fiber count. After evaluating this data and other physical characteristics, K-S will review your application and recommend the proper filter medium for your specific application.

Filter Leaf Testing

The specific performance of a filter may be predicted by conducting leaf tests. The tests simulate the operation of a continuous filter through a series of steps involving cake formation, draining, washing (when required), final drying, and discharge. Leaf tests provide comparisons of various media with yield and operating data.

Testing can be conducted either in the K-S liquid/solid separation laboratory or in your own plant. Leaf test kits with operating instructions and media samples are available for direct customer use.


Komline-Sanderson offers both synthetic and natural materials. Each fiber has its own different mechanical and filtration characteristics when woven or processed into a filtration medium. These various fiber types can be woven into many different patterns, which produce specific mechanical and filtration characteristics. K-S offers a variety of these patterns, including the “plain weave,” “twill weave,” and “satin weave.”

After the medium has been selected, correct stabilization and fabrication techniques will aid in providing the longest possible operating life. Since dimensional stability of the fabric is of critical importance in most applications, K-Semploys methods of fabric stabilization and cloth fabrication to produce a product that is superior in performance and life. Special fabrication techniques and custom designs, such as webbing, grommets, closures, and reinforcements are offered to meet your specific needs.

A wide variety of belt closures and edge seals are available for all types of continuous vacuum filters, including Rotary Drum Vacuum Filters and Horizontal Vacuum Filters. Heavy duty envelope material with a stainless steel coilspring to provide a resilient end member is available for most manufacturers’ filters. Rubber profiles for belt tracking are also available.

How do I order Filter Fabrics?

  • Specify type and size of filter, including number of plates, leaves, or sections. Replacement fabric orders for Komline-Sanderson filters require only the K-S job number.
  • For filters other than Komline-Sanderson, specify the exact size of the existing filter cloth (unless a K-Sreference number has already been assigned).
  • Orders involing a change in existing filter fabric to improve unit performance should specify process conditions as follows:
    • pH of slurry being filtered
    • slurry temperature
    • chemical composition of both liquid and solid phases
    • particle size range and physical conditions of solids, if known
    • Type of synthetic or natural fiber preferred.
    • If possible, send a sample of the filter medium currently in use.
