Filter Systems · KF
Cartridge Filter Systems
SOLO, DUPLEX & MULTIPLEX in LIGHT, STANDARD and EXTRA-LINE — from the ECO version ("Sound Engineering Practice") up to CE-marked Category IV.
DUPLEX
Two (or more) hard-piped cartridge filters — optionally with manual or automatic change-over for continuous operation.
MULTIPLEX
A single vessel unit with a unified closure, in which two or significantly more filter cartridges are combined depending on the filtration capacity.
EXTRA-LINE options: performance, materials, coatings, heating, mobility, safety
When the STANDARD-LINE is not enough: higher throughput and output, advanced materials (Hastelloy, titanium, carbon steel, plastics), coatings (HALAR®, ETFE, FEP, PFA, PTFE, PU), heating jacket, filter trolleys for mobile use, as well as explosion protection according to ATEX, TA Luft and FDA/EC conformity.
Filter Systems · SKF
Basket Filter Systems
Robust systems for high flow rates and coarse filtration — in the same three configuration levels: LIGHT-, STANDARD- and EXTRA-LINE (up to 100 bar / 400 °C, all PED categories).
LIGHT-LINE
ECO design according to “Sound Engineering Practice” (Art. 4 Para. 3 PED) — up to 10 bar / 80 °C.
STANDARD-LINE
All-rounder for all applications and approvals — up to 16 bar / 150 °C, categories I–IV.
EXTRA-LINE
Premium options for maximum performance — up to 100 bar / 400 °C, special materials and coatings.
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.
Liquid-Solid Separation
Nutsche Filter / Pressure Filter
Up to 6 bar operating pressure, heatable (vessel jacket + thermostat), mobile on filter trolley. Typical applications in Pharma & Chemicals: Activated carbon filtration, separation of filter aids and salts, catalyst, clarification, sterile and recyclables filtration, API extraction.
Continuous Filtration
Edge Filter / Wedge Wire Filter
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.
Filter Media
Filter Bags & Fiber Filter Meshes
Bags, rolls and cut-to-size pieces — standard or custom-made, available with FDA/EC compliance for food and cosmetics upon request.
Monofilament Filter Bags
Polyester, polypropylene & Nylon™ (NMO). The melt-welded monofilament mesh enables surface filtration with an absolute retention rate at a clearly defined pore size.
Needle Felt Filter Bags
Polyester, polypropylene & aramid (NOMEX®) — depth filtration with high dirt-holding capacity, also available in XL versions (PEXL/POXL).
Other Materials & Mesh Bags
Cotton, fiberglass, PTFE (Teflon™) etc. — plus mesh bags and filter mesh as rolls or cut-to-size pieces.
In EXTRA versions, standard specifications (e.g. length, diameter) can be varied — we implement individual application-specific requirements in consultation with you.
Filter Media
Filter Candles made of Fibers & Metal
Six designs for every fineness and resistance requirement — used individually or in multiples in candle filter housings.
Activated Carbon Filter Candles
Porous activated carbon block with PP pre-filter and support body — also FDA/EC compliant. The filtrate flows from the outside through the activated carbon element and is discharged via the inner support core.
Meltblown Filter Candles
Depth filtration (nominal & absolute) with thermally bonded microfibers made of polypropylene or polyamide — with or without support core, FDA compliant.
Membrane Filter Candles
Absolute filter candles for fine filtration made of PES, PTFE or PA with a polypropylene support core — according to FDA requirements.
Metal Filter Candles
Surface filters made of metal (composite) mesh (stainless steels) with very high resistance to heat and chemicals.
Pleated Filter Candles
Depth filter elements made of pleated polypropylene microfibers — high dirt-holding capacity, FDA/EC compliance.
Wound Filter Candles
Depth filtration with yarns made of polypropylene, cotton or glass fiber and support bodies made of polypropylene or stainless steel.
Metal filter mesh
Strainer baskets & other components made of metal filter mesh
Strainer baskets, support baskets, wedge wire screens, filter discs, hat strainers, insertion strainers and more — for the surface filtration of liquid and gaseous media.
Strainer baskets & filter inserts
Strainer and support baskets made of stainless steel, carbon steel & plastic — various sizes, filter ratings, hole diameters and pitches.
Formed parts & filter elements
Filter discs, fluidization cones & mushrooms, hat strainers, strainers, wedge wire screens & insertion strainers.
Custom cuts & sheets
Metal filter mesh for surface filtration — smooth or pleated, single or multi-layer. Composite meshes combine various wire meshes across the entire surface to create robust fine filter media.
Key advantages of metal filter meshes — particularly those made of (stainless) steel — include very high heat resistance and structural strength.
Air Filtration
Pocket Filters, Dust Filters, Filter Cells & Mats
Coarse dust, fine dust and HEPA filters — as standard or custom versions, ready-to-use or as roll goods, optionally FDA/EC compliant.
Particles > 10 µm
Coarse Dust Filters
Pocket filters, filter sleeves, dust bags and filter mats for the separation of coarse particles.
Particles 1–10 µm
Fine Dust Filters
Fine dust pocket filters and cells in various filter classes, sizes and materials.
Particles < 1 µm
HEPA Filters
Maximum separation efficiencies for sensitive applications and clean process air.
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, during imminent production downtime — 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 media.
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
Displacement bodies in the filter bag reduce the amount of residual filtrate — this significantly simplifies bag changes.
