Standard Feedthrough Common Specifications
Some of Ferrotec's Ferrofluidic® seal specifications are common to the majority of our feedthroughs.
| Temperature Range (Uncooled) | 20 – 210°F (-6 – 100°C) |
Water cooled units may exceed these temperatures. Most unites are bakeable to 150°C. |
| Vacuum Pressure | 10-9 mbar | Estimated Value. Actual performance will depend on system pumping speed and other gas loads. |
| Leakage Rate (mbar I/s) | 10-11 mbar I/s | Units not regularly tested to this level as it is beyond the capability of common vacuum equipment. |
| Gas compatibility | inert gas | For sealing in reactive environments, a flourocarbon-based ferrofluid may be required. |
| Housing Material | 300 series stainless steel | ISO 1.4301 or similar |
| Shaft Material | 400 series stainless steel or 17-4 PH |
ISO 1.4000 or similar ISO 1.4542 or similar |
| Maximum shaft run-out | 0.003"/0.076mm |
