Industrial & Specialty Filter Products

There are many critical filtration applications in the making of specialty chemicals, ink jet ink, and other industrial and service processes. A wide range of filtration devices are needed to cost-effectively produce the quality fluids you need to succeed in your business. Critical Process Filtration designs and manufactures filters for use in specific industries. Choose from a wide range of filter devices with multiple membranes and media and a wide range of micron ratings to deliver the filter performance you need in the most cost-effective way possible.

Media

Our polyethersulfone (PES), nylon, hydrophilic polyvinylidene fluoride (PVDF), hydrophobic polyvinylidene fluoride (PVDF), polypropylene and PTFE membranes, pleated and melt-blown polypropylene depth media and pleated fiberglass media are available in formats for all flow ranges of process filtration applications. Disc filters support small scale flows in test and research laboratories. Small capsule filters are available for low flow applications such as bench scale systems or other small scale systems. Our large disposable capsule filters and cartridge filters and cartridge filter housings are used for larger flow applications ranging from a few gallons a minute to over a thousand gallons per minute of flow.

Services

All of our filters are designed for use in their end-use industries. We also offer other Services to help you choose the right filter for your application.

In addition to our standard cartridge and capsule filters, we offer specialty filters using activated carbon block and stainless steel media as well as yarn wound cartridgs and bag filters with multiple material options. See the selections below.
