DN25–DN40 self-cleaning filter
For compact industrial systems and lower flow rates, the FSC-50 provides automatic scraper cleaning with DN25, DN32 and DN40 connection options.
Self-cleaning filters are used in industrial liquid filtration systems where continuous removal of suspended solids is required without disposable filter cartridges or filter bags. These filtration systems use wedge wire filter elements combined with scraper cleaning mechanisms to maintain stable operation during filtration.
Industrial self-cleaning filtration systems are commonly used in water treatment, coatings, chemicals, oils and process liquids where reliable particle removal and minimal maintenance downtime are essential.

FSC self-cleaning filter range
Choose the right self-cleaning wedge wire filter
The FSC range consists of stainless-steel scraper-type self-cleaning filters for continuous industrial liquid filtration. Models are available from compact DN25 systems through to DN100 high-flow filters, with filtration ratings from approximately 25 to 3000 µm.
Selection should be based on more than flow rate alone. Connection size, liquid viscosity, particle characteristics, solids loading, operating pressure, temperature and required micron rating all influence the correct filter size and configuration.

Compare FSC self-cleaning filter models
Use the table below as an initial selection guide. The stated flow capacities are reference values and should not replace application-specific sizing.
| Model | Connection | Reference flow | Micron range | Cleaning | Best starting point for |
|---|---|---|---|---|---|
| FSC-50 | DN25 / DN32 / DN40 | Up to approx. 3.5 m³/h | 25–3000 µm | Automatic scraper | Compact and lower-flow process filtration |
| FSC-70 | DN50 | Up to approx. 13 m³/h | 25–3000 µm | Automatic scraper | Medium-capacity industrial liquid filtration |
| FSC-110 | DN65 | Up to approx. 25 m³/h | 25–3000 µm | Automatic scraper | Medium-to-high process flow rates |
| FSC-175 | DN80 | Up to approx. 35 m³/h | 25–3000 µm | Automatic scraper | Higher-capacity continuous liquid filtration |
| FSC-325 | DN100 | Up to approx. 70 m³/h | 25–3000 µm | Automatic scraper | High-flow industrial filtration systems |
| FSC-50M | 1" BSP / DN25 | Up to approx. 3.5 m³/h | 25–3000 µm | Manual | Simple lower-flow manual filtration |
Reference flow values depend on the liquid and process conditions and are typically based on water-like liquids at approximately 100 µm. Higher viscosity, finer filtration ratings and increased solids loading can reduce achievable flow. Final sizing should therefore be confirmed for the actual application.
Self-cleaning filter selection by connection size
DN50 and DN65 self-cleaning filters
The FSC-70 DN50 and FSC-110 DN65 cover medium industrial flow requirements up to approximately 13 and 25 m³/h respectively.
DN80 and DN100 self-cleaning filters
Higher-flow installations can use the FSC-175 DN80 or the FSC-325 DN100, with reference capacities up to approximately 35 and 70 m³/h.
What information is needed to size an FSC filter?
For accurate selection of an industrial self-cleaning filter, Filtra International evaluates the required flow rate, pipe connection, micron rating, liquid viscosity, solids concentration, particle characteristics, pressure, temperature and chemical compatibility. These parameters determine the required filtration area, filter model, wedge wire opening and cleaning configuration.
FSC self-cleaning filters are commonly applied to industrial water, paints and coatings, adhesives, resins, oils, lubricants, chemicals, solvents, emulsions and other process liquids where continuous solids removal and reduced consumption of disposable filtration media are required.
