9. Technical Data
1) Measured with a rotary vane pump 10 m3/h; higher throughputs with
reduced rotation speed.
2) Rotation speed of pump may drop below the nominal rotation speed.
3) For gas type characteristic lines please refer to section 4.4.
4) In accordance with German Industrial Standard 28428 the 48 hours
after baking out.
5) At maximum gas throughput.
6)
Protection class IP 54 is afforded for the Electronic Drive Unit TC 100
with a 15 pole D-Sub plug (accessory).
