The Leybold TURBOVAC TW 300 (P/N 800170V2101) is a high-performance, compound-stage turbomolecular pump designed for clean high-vacuum (HV) and ultra-high-vacuum (UHV) applications. Featuring a compact profile, grease-lubricated ceramic bearings, and robust foreline pressure tolerance, the TW 300 delivers exceptional reliability and low vibration for sensitive laboratory and analytical environments.

Equipped with a DN 100 ISO-K inlet flange, this unit is widely utilized across semiconductor processing, mass spectrometry, surface analysis, and general R&D vacuum systems.

Key Features & Benefits

High Pumping Efficiency: Delivers pumping speeds up to 240 l/s ( $N_{2}$ ) with high compression ratios for light gases ( $H_{2}$ , $He$ ).
DN 100 ISO-K Inlet: Standard claw-clamp style high-vacuum connection for fast installation and integration.
High Foreline Tolerance: Allows pairing with downsized backing pumps (e.g., small rotary vane or dry diaphragm pumps).
Clean Hydrocarbon-Free Vacuum: Ideal for oil-sensitive analytical instruments and semiconductor process chambers.
Low Noise & Vibration: Precision-balanced rotor assembly ensures quiet operation ( $< 49 dB(A)$ ).
