I'm reaching out to get some clarification regarding one of your turbo molecular pump models. Specifically, I'm curious about its operational requirements. Does it require a separate controller to function properly, or is it designed to operate independently without one? Understanding this aspect is crucial for us, as it will influence our purchasing decision. Additionally, I'd appreciate any further details you could provide regarding its installation and compatibility with different systems. If there are specific configurations or additional components needed for optimal performance, please let me know. This info will help us assess our options and ensure we make an informed decision. Looking forward to your response!
