Filter Systems · SPF / SPECIAL-LINE

Special Filter Systems — for unique and demanding requirements

Specialized tasks and projects with the highest application-specific requirements are developed and implemented within the SPECIAL-LINE — including combinations of different technologies.

Solid-Liquid Separation

Pressure Nutsche Filter / Pressure Filter

Up to 6 bar gauge operating pressure, can be heated (vessel jacket + thermostat), mobile on a filter trolley. Typical applications in pharmaceuticals & chemicals: activated carbon filtration, separation of filter aids and salts, catalyst filtration, clarification, sterile filtration, valuable material filtration, and API recovery.

Continuous Filtration

Edge Gap Filters / Wedge Wire Filters

For maximum performance and specific application requirements — continuous filtration even for high-viscosity media.

Continuous Filtration

Automatic Backwash Filters

Self-cleaning systems for continuous operation — the filter elements are automatically backwashed without interrupting the process.

Accessories & Rental Systems

Accessories for efficient filtration

Adapters, ball valves, bolts, clamps and much more

Butterfly valves, adapters, eyebolts, ball valves, pressure gauges, clamps, drip trays, valves and centering screws for Schoneweg filter systems.

Bag/sleeve positioners & backflush supports

Ensure correct installation and seating of the filter bag or sleeve and prevent the bag from "fluttering" and potentially bursting due to uncontrolled back pressure.

Rental filter systems

When rapid assistance is needed — for instance, when production downtime is imminent — we provide a suitable filter system as a temporary solution by arrangement.

Magnetic rods

Inserted into the filter bag during filtration to capture magnetic particles such as swarf or fine dust before they accumulate on the filter medium.

O-rings & flat gaskets

Application-specific seals made of E-CTFE (Halar™), ETFE, FEP (FEP-Teflon™), PTFE (PTFE-Teflon™), PVDF, EPDM, FPM/FKM (Viton™), NBR and silicone rubber.

Displacers

Displacers in the filter bag reduce the amount of residual filtrate — making bag changes significantly easier.
