Industrial filters with pneumatic valve assembly
These industrial filters are designed for water treatment installations requiring reliable, automated pretreatment. They can be used for different filtration stages: iron / manganese removal, softening / decalcification or dechlorination with activated carbon.
Each filter is equipped with a pneumatic valve assembly to automate service and backwash cycles. The filters operate in parallel depending on the installation configuration.
General components
- FRP tank with filter strainers
- FVN90 or FVN110 pneumatic valve assembly depending on the model
- 5 stainless steel butterfly valves with flanged connections
- Single-acting pneumatic actuators
- Electrical control panel with Siemens Logo! PLC
- PVC piping
- AISI 304 stainless steel support frame
- Vent valve
- Inlet and outlet pressure gauges
