Our Membrane Filter Capabilities

We offer OEM capabilities for engineering, molding and insertion of many additional membrane and membrane/pre-filter options. We can work with most of our own membrane and specialty materials as well as convert your supplied product. Please contact us for full engineering capabilities as well as process flow and project management services in this field.

• Filter insertion in clean room by manual as well as fully automated means
• Molding in place, over molding and support structure molding of fragile media
• Ultrasonic welding of barrel structure for increased leak / burst resistance
• Multi-process mold extensions for inclusion of single or multi-level prefiltration media
• Digital variable print capabilities along arc on barrel face for identification purposes
• Blister packing for EO and gamma sterilization
• Pure virgin PP, verified by HPLC against U/L extractables

Tremont offers an impressive list of manufacturing capabilities and expertise in glass microfiber and cellulose filter media. We leverage a longstanding and contractual relationship between several mills to put 6 papermaking machines and formers into production. With this enormous capacity at our disposal, we are able to take a project from lab bench through pilot scale and ultimately full production with ease.

Our partner mill output exceeds 120 grade variants manufactured in the USA and internationally. With chemists and scientists of several disciplines, experienced papermakers, the finest controls-on-machine plus a rigorous QA protocol, it is not often a project challenge is beyond our capability.
