DN80 Self-Cleaning Wedge Wire Filter – Up to 35 m³/h
The FSC-175 is a DN80 industrial self-cleaning filter for continuous liquid filtration with reference flow rates of up to approximately 35 m³/h. The system uses a reusable stainless-steel wedge wire element combined with mechanical scraper cleaning to remove suspended solids without routine replacement of filter bags or cartridges.
With DN80 PN16 flanged inlet and outlet connections and a large filtration surface, the FSC-175 is designed for medium-to-high-capacity industrial processes including water, paints and coatings, adhesives, resins, oils, lubricants, solvents, emulsions and other process liquids.
Flow reference: approximately 35 m³/h is specified for water at a filtration rating of approximately 100 µm. Actual flow capacity depends on viscosity, solids loading, filtration rating, pressure drop and process conditions.

How does the DN80 self-cleaning filter work?
Process liquid enters the filter housing through the DN80 inlet and reaches the outside of the cylindrical wedge wire filter element. The liquid passes through the precision filter slots from outside to inside, while suspended particles are retained on the outer surface.
During the cleaning cycle, the motor-driven assembly moves the filter element relative to the scraper so deposited contamination is mechanically removed from the wedge wire surface. The separated solids fall into the lower sediment section of the filter housing.
The collected solids can subsequently be discharged through the drain connection using system pressure. The screen-cleaning process takes place while the main filtration process continues.
When should a DN80 self-cleaning filter be considered?
A DN80 self-cleaning filter is generally suitable for industrial process lines requiring more filtration area and flow capacity than a DN50 or DN65 system, while a DN100 filter may be unnecessarily large.
With approximately 1055 cm² of filtration area and a reference flow of up to 35 m³/h, the FSC-175 provides a practical intermediate size for demanding continuous-filtration applications.
- DN80 industrial pipelines
- Flow requirements up to approximately 35 m³/h under reference conditions
- Continuous liquid-filtration processes
- Processes with elevated suspended-solids loading
- Viscous liquids that can be difficult to clean by backwashing
- Applications where disposable filter changes cause maintenance or product loss
25 to 3000 micron DN80 filtration
The FSC-175 can be equipped with stainless-steel wedge wire elements from approximately 25 to 3000 µm. Common filtration ratings include:
- 25 µm
- 50 µm
- 100 µm
- 250 µm
- 500 µm
- 1000 µm
- 3000 µm
The required micron rating directly influences achievable flow and cleaning frequency. Fine filtration, high viscosity and high solids concentrations can reduce the flow capacity compared with the 35 m³/h reference value.
Stainless-steel construction and seal options
The DN80 self-cleaning filter is constructed for industrial service using corrosion-resistant stainless-steel components.
- Filter housing: stainless steel 1.4404 / 1.4571
- Wedge wire element: stainless steel 1.4404
- Scraper blade: stainless steel 1.4310
- Industrial worm gear drive
- Seal materials selected according to liquid compatibility
- EPDM, FKM/Viton and PTFE configurations available depending on application
The final material and sealing configuration should always be checked against chemical composition, operating pressure and temperature.
Industrial DN80 filter design
The FSC-175 combines a relatively large wedge wire filtration surface with a compact vertical industrial housing. Its mechanical scraper system is designed to maintain the available screen area by continuously or periodically removing deposited solids.
- DN80 PN16 inlet and outlet connections
- 1055 cm² wedge wire filtration surface
- Motor-driven mechanical scraper cleaning
- External-to-internal filtration
- Integrated lower solids collection chamber
- Connections for differential-pressure measurement
- Optional automated solids discharge
Solids discharge and automatic control
Contamination removed from the screen accumulates in the lower section of the housing. The discharge process can be adapted to the amount and type of contamination.
- Manual discharge using a drain valve
- Automatic time-controlled discharge
- Differential-pressure-based cleaning or discharge control
Automatic control can reduce operator involvement in applications with predictable or higher solids loading.
Typical DN80 self-cleaning filter applications
The FSC-175 can be applied to a broad range of industrial liquids where suspended solids must be removed continuously or where disposable filtration becomes maintenance intensive.
- Industrial and process water
- Paints and coatings
- Printing inks
- Adhesives and resins
- Industrial oils and lubricants
- Cooling lubricants and emulsions
- Solvents and chemical process liquids
- Polymer and polyurethane processing
- Selected food-process liquids
- Protection of pumps, valves and downstream equipment
How to size a DN80 self-cleaning filter
DN80 pipe size alone does not determine the correct filter. Proper sizing should consider the complete process conditions:
- Required flow rate in m³/h
- Required filtration rating in µm
- Liquid type and viscosity
- Solids concentration
- Particle size, shape and behaviour
- Operating pressure
- Operating temperature
- Chemical compatibility
- Cleaning and discharge requirements

DN80 self-cleaning filter FAQ
What flow rate can the DN80 FSC-175 handle?
The FSC-175 has a reference maximum flow rate of approximately 35 m³/h. This value is based on water at approximately 100 µm. Actual flow depends on viscosity, solids concentration, filtration rating and process conditions.
What connections does the FSC-175 use?
The FSC-175 uses DN80 PN16 flanged inlet and outlet connections. The solids discharge connection is a 2-inch BSPP internal thread.
What micron ratings are available for the DN80 filter?
Wedge wire elements are available from approximately 25 to 3000 µm, including common filtration ratings of 25, 50, 100, 250, 500, 1000 and 3000 µm.
What is the filter surface area of the FSC-175?
The FSC-175 provides approximately 1055 cm² of wedge wire filtration area.
Can the DN80 filter clean itself while filtration continues?
Yes. The mechanical scraper system removes deposited solids from the wedge wire surface while the main liquid filtration process continues.
What pressure can the FSC-175 handle?
The standard operating range is 0 to 10 bar. Higher-pressure configurations up to 16 bar may be available depending on the final specification.
Is the DN80 FSC-175 manufactured in the EU?
Yes. The filter is manufactured in the European Union and is specified according to PED 2014/68/EU, Category I, Module A.
Should I choose DN65, DN80 or DN100?
Selection depends on flow rate, viscosity, micron rating, solids loading and process conditions. As an initial reference, the FSC-110 DN65 is rated up to approximately 25 m³/h, the FSC-175 DN80 up to approximately 35 m³/h and the FSC-325 DN100 up to approximately 70 m³/h under reference conditions.
