This unit is tested working and pulled down to 8.5×10^⁻8 Torr in our setup (with no bakeout) as shown in the photos using an ion gauge. It can perform even better if baked out. Flange size is ISO 100 ISO-K 100.\u003c\/p\u003e \u003cbr\u003e \u003cp dir=\"ltr\" style=\"margin-top:0; margin-bottom:0; text-align:start;\"\u003eWe pumped it down on our turbo test station, and it worked well as expected.

This unit is the ISO-K 100 inlet variant and includes a dedicated power supply\/controller; factory-rated pumping speed on ISO 100 is 250 L\/s (N₂), 220 L\/s (He), 200 L\/s (H₂) with compression ratios N₂ \u0026gt; 2×10⁸, He 1×10⁵, H₂ 2×10⁴; it spins to 56,000 rpm with \u0026lt;3 min run-up, uses permanently lubricated ceramic bearings, and works in any mounting orientation. Foreline connection is KF16 NW; cooling is natural convection, noise is ≤45 dB(A) at 1 m, and bakeout limits are 80°C max at the ISO inlet flange. The controller is a microprocessor-driven frequency converter; mains versions take 100-240 Vac, 50-60 Hz with 300 VA max input and 150 W max operating power; plus serial control and PWM speed-set capability if you’re integrating into a bigger system. We bench-tested this pump on our turbo station and it pulled down to 8.5×10⁻8 Torr on our ion gauge setup (see photos); what you get is a known-good turbo+controller combo.\u003c\/p\u003e \u003cbr\u003e \u003cbr\u003e \u003cp dir=\"ltr\" style=\"margin-top:0; margin-bottom:0; text-align:start;\"\u003eZV\u003c\/p\u003e \u003cbr\u003e \u003cbr\u003e","brand":"Lab Liquidators Store","offers":[{"title":"Default Title","offer_id":52046973796644,"sku":"SP111116857","price":1799.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/5289\/2964\/files\/406723882867-0.jpg?v=1772144362","url":"https:\/\/store.labliquidators.com\/products\/tested-to-e-8-torr-varian-tv301-nav-turbo-vacuum-pump-9698918-and-power-supply","provider":"Lab Liquidators Store","version":"1.0","type":"link"}
