Sintered filters
Materials
The FILPOR filter elements are produced by sintering sifted metal powders in order to achieve different porosities depending on the particle size used. In the case of bronze, the alloy composition used is 90% Cu - 10% Sn.
Filters are also offered in AISI 316 stainless steel.
Bronze Porosity Ratings
| Code | IB-1 | IB-2 | IB-3 | IB-4 | IB-5 | IB-6 | IB-7 | IB-8 | IB-9 |
| Microns | 8 | 12 | 24 | 40 | 60 | 85 | 100 | 150 | 200 |
A particle with a diameter larger than the porosity rating shown in the table will not pass through the filter.
Corrosion Resistance
The corrosion resistance of these elements is equivalent to that of solid material of the same composition.
Temperature Limits
Operating temperature limits in air range from -250 ºC to 150 ºC.
Applications
- ✔ Gas and liquid filtration
- ✔ Liquid separation
- ✔ Protection of pneumatic solenoid valves
- ✔ Protection of metrology probes
